Overview¶

Tibial plateau fractures result from varus or valgus forces combined with axial loads, typically from a fall from height [12]. The magnitude, type, and direction of these forces dictate the fracture pattern, with greater energy absorption by the proximal tibia leading to more severe displacement and comminution [2]. Axially loading forces are generally more rapid and release greater energy than angular forces [2]. The proximal tibia is most likely subjected to a valgus force due to the normal 5 to 7 degrees of valgus alignment of the knee and a propensity to be struck from the lateral side [2]. A combination of valgus and axial compression produces lateral-side depression, split depression, or less commonly, lateral split or total lateral condyle fractures [2]. Younger patients with good bone tend to have split fractures with less depression, while elderly patients with osteopenic bone have a greater component of compression with a less prominent split fragment [2]. Varus injuries lead to failure of the medial plateau, which can involve the entire medial plateau or extend into the lateral plateau [2]. A posteromedial shearing fracture of the medial plateau is a common medial-side pattern that can occur as an isolated split fracture or as part of a bicondylar fracture pattern in as many as one-third of bicondylar fractures [2]. Tibial plateau fractures most often occur with the leg in a weight-bearing position, so axial load is typically some component of the injuring force [2]. Bicondylar patterns result when axial load predominates, with severity varying based on the magnitude of the axial forces [2]. Metaphyseal tibial plateau fractures from direct trauma or a combination of axial load and bending forces are associated with a high risk of complications including open fractures, severe closed soft tissue injury, trifurcation injury, and compartment syndrome [2]. Varus hyperextension injuries are characterized by tension failure of the posterior cortex and compression of the anterior cortex with varus deformity in the coronal plane [2]. In one study of bicondylar tibial plateau fractures, 13 of 41 patients had other major skeletal injuries in addition to the plateau fracture, which affected functional outcome [2]. Knee dislocation events were identified or confirmed based on MRI in 46% of Schatzker type IV patterns [2]. Schatzker type IV, V, and VI patterns demonstrated a high incidence of ligament injury [2]. High-energy tibial plateau fractures have a small risk of vascular injury and a high risk for compartment syndrome [2].

Nonoperative treatment is indicated for undisplaced or minimally displaced fractures, small depressions of the lateral plateau without deformity or instability on clinical exam, patients with significant medical comorbidities that preclude surgical treatment, and elderly patients with low functional demands in whom subtle deformities are tolerated [1]. Knee instability, greater displacement where deformity is easily predictable, and displaced medial-side injuries are relative contraindications for nonoperative treatment [1]. Undisplaced or incomplete fractures may be treated nonoperatively with good results [1]. Nonsurgical management can be considered in patients who present in a delayed manner or for whom surgical treatment is not advisable due to multiple medical comorbidities or high risk for morbidity and mortality from anesthesia [1]. The proximal tibial articular surface tolerates small-to-modest articular displacements, and in properly selected fractures, nonoperative treatment results in predictably excellent outcomes despite articular irregularities [1]. Progressive incapacitating posttraumatic arthritis is actually very unusual after nonoperative treatment of properly selected tibial plateau fractures [1]. There are no consensus guidelines regarding nonoperative treatment of tibial plateau fractures [1]. In current practice, it is rare to obtain a closed reduction of a displaced proximal tibia fracture for definitive nonoperative management, and for many displaced fractures, it is impossible [1]. Angular malalignment is not tolerated after tibial plateau fracture and causes more loading of the articular cartilage of the injured condyle [1]. Malalignment may be cosmetically unacceptable, increases the propensity for knee instability, and can cause balance issues and lead to falls [1]. Localized depressions up to 10 mm or more may result in a stable knee with good clinical outcomes [1]. Fractures involving large segments of the lateral tibial plateau plus split depression fracture patterns are likely to lead to valgus malalignment [1]. Some Schatzker type II lateral tibial plateaus are amenable to nonoperative treatment with minimal risk of deterioration, especially when the size of the fractured plateau is relatively small [1]. Medial plateau fractures have a greater propensity to subside as the weight-bearing axis of the lower limb crosses slightly medial to the midline [1]. Subsidence or collapse of the medial plateau can lead to varus deformity [1]. Carefully selected patients with minimally displaced tibial plateau fractures can expect good to excellent outcomes when treated nonsurgically [6]. Undisplaced type 1 tibial plateau fractures can be treated conservatively with a hinged cast-brace or ROM brace to allow early mobilization, with weight-bearing restricted initially [12]. For Schatzker Type 2 fractures, if the knee is stable and depression is less than 5 mm, or in a low-demand patient or osteoporotic fracture, non-operative treatment focused on regaining mobility and function early rather than anatomical restitution is appropriate [12]. Regardless of the treatment type, no differences in patient-reported outcomes were seen at midterm follow-up when patients treated surgically and those treated nonsurgically for tibial plateau fractures with displacement up to 4 mm were compared [21]. Benefits of surgery for minimally displaced tibial plateau fractures (up to 4 mm displacement) were not observed at a mean of 6 years after surgery, suggesting a need for a careful reappraisal of indications for ORIF [83]. Poor bone quality should not be used as an indication for nonoperative management of tibial plateau fractures [22].

Displaced type 1 tibial plateau fractures must be reduced and fixed [12]. Reduction of displaced type 1 fractures may require removal of incarcerated fragments or cartilage [12]. Fixation of type 1 fractures can be achieved with lag screws in good bone or a buttress plate in poorer bone [12]. For Schatzker Type 2 fractures requiring surgery, open reduction with elevation of the plateau and internal fixation is required [12]. Joint surface inspection via submeniscal arthrotomy or arthroscopically is recommended for Schatzker Type 2 fractures [12]. Screws can be placed in parallel just beneath the subchondral bone ('raft' screws) to support the articular surface in Schatzker Type 2 fractures [12]. Bone graft may help in the treatment of Schatzker Type 2 fractures [12]. The wedge of the lateral condyle in Schatzker Type 2 fractures is fixed with a buttress plate [12]. Periarticular locking plates are popular but not always necessary for Schatzker Type 2 fractures [12]. Early knee movement is encouraged to minimize joint stiffness after Schatzker Type 2 fracture fixation [12]. Plates and screws are the most frequent implants used to stabilize tibial plateau fractures [54]. Lag screws are used to compress simple fracture lines in isolation or in conjunction with other fixation devices [54]. Partially threaded screws are most common for compression, with 6.5-mm screws working well for major plateau fracture lines [54]. Anterolateral plates are used as a buttress and to substitute for the damaged lateral cortex that occurs with lateral split depression plateau fractures [54]. 3.5-mm implants and screws are the most common size, having largely supplanted 4.5-mm implants [54]. 3.5-mm implants are less bulky and easier to fit on the bone, allowing more screws to be placed closer to the articular surface [54]. Multiple holes in the head of the plate allow 3.5-mm screws to be placed parallel and close to the articular surface to support reduced fragments, a technique termed "rafting screws" [54]. Posteromedial plates function as an antiglide device to resist shearing forces [54]. In posteromedial plate application, the plate position in relation to the apex of the fracture is more important than the exact placement of screws [54]. Lateral plates used for bicondylar and Schatzker type VI fractures must resist axial, rotational, and bending forces [54]. Locking screws to the plate have been a major advance in resisting mechanical forces in bicondylar and Schatzker type VI fractures [54]. Plate constructs for bicondylar and Schatzker type VI patterns may be bigger (e.g., 4.5 mm) than those used for unicondylar fractures [54]. Lateral plates for bicondylar fractures must prevent the tendency of bending forces to create a varus deformity [54]. Lateral plates for bicondylar fractures are generally considered insufficient in providing support for an unstable medial column [54]. The use of locking screws for unicondylar tibial plateau fractures where the plate functions as a buttress or antiglide is of uncertain value [54]. Satisfactory results can be obtained in most carefully selected elderly patients with displaced tibial plateau fractures, provided meticulous surgical technique is observed and sufficient quantities of bone graft are filled in the defect to prevent postoperative collapse [11]. Operative treatment of displaced tibial plateau fractures in patients older than 55 years can result in favorable outcomes as evaluated by clinical, radiographic, and self-assessment criteria [32]. Elderly patients without significant co-morbidities seem to be appropriate candidates for ORIF of their tibial plateau fractures [80]. Impaction bone grafting shows promising results as an adjunct to the surgical stabilisation of osteoporotic tibial plateau fractures [36]. Porous titanium granules are beneficial to use rather than autograft bone to fill the void created by reducing a depressed fracture of the lateral tibial plateau [62]. Early weight bearing can be considered safe and effective in selected cases after internal fixation for tibial plateau fractures [79]. Patients who have elective removal of their surgical implants after open reduction and internal fixation of a tibial plateau fracture have improved clinical outcomes and demonstrate significantly better outcomes than those who have retained implants at final follow-up [34]. The postero-medial approach is a safe and practical method of treating complex tibial plateau fractures with good outcomes [14]. Good outcomes were achieved utilizing a modern column specific approach to the treatment of two or more column tibial plateau fracture injuries, which includes assessment of three columns [10]. Surgeons should consider using the arthroscopic approach when treating patients with tibial plateau fractures [31]. The arthroscopic procedure is recommended in selected tibial plateau fractures [64]. Open intrameniscal examination and reduction is proposed as an advancement over conventional methods for the reduction and internal fixation of depressed tibial plateau fractures, particularly in open surgical indications and rim depressions [86].

Patient-reported outcomes continue to improve beyond one year following tibial plateau fracture, at least in a statistical sense, if not also clinically [8]. Older patients and those with more severe fractures are more likely to need total knee arthroplasty after repair of a tibial plateau fracture [20]. The common reasons for the failure of primary surgery of complex tibial plateau fractures were inadequate experience of the surgeon, inaccurate diagnosis and management, improper selection of implants, and poor surgical techniques [5]. Operative treatment of tibial plateau fractures is a good option [30]. Findings regarding acceptable sizes of gaps and stepoffs in nonoperative management cannot be extrapolated to all tibial plateau fracture types [9].

Anatomy & Pathophysiology¶

Bony Anatomy¶

The knee possesses an average anatomic axis of 6° of valgus [17], while the proximal tibia is in 3° of varus, with the lateral plateau sitting slightly higher than the medial plateau [17]. The lateral tibial plateau is smaller and convex, whereas the medial tibial plateau is larger and concave [17]. The medial plateau accommodates 60% of the weight distributed through the knee [17], resulting in increased bone density of the medial plateau according to Wolff's law [17]. The lateral plateau is affected exclusively in 55% to 70% of tibial plateau fractures [17], while medial plateau unicondylar fractures occur in 10% to 23% of cases [17] and bicondylar fractures occur in 10% to 30% of cases [17].

The proximal tibia flares from the diaphysis, with the anterior proximal tibia widening to form the tibial tubercle for patellar tendon attachment [25]. The proximal lateral tibia abruptly flares to form the lateral tibial condyle, which serves as the origin of anterior compartment muscles and has Gerdy's tubercle for iliotibial band insertion [25]. The articular surface of the lateral tibial plateau is flat or slightly convex [25], while the medial tibial plateau is concave and provides greater congruity with the medial femoral condyle than the lateral side [25]. The proximal articular surface slopes from proximal (front) to distal (back) relative to the shaft [25]. The range of varus coronal slope is between −1 and 6 degrees [25], and the sagittal slope ranges from 0 to 14 degrees on the lateral side and −3 to 10 degrees on the medial side [25].

The tibial shaft is triangular in cross section [65]. The tibial tubercle is located anterolaterally about 3 cm distal to the articular surface and is the point of attachment for the patellar tendon [65]. Gerdy’s tubercle is located laterally on the proximal tibia and is the point of insertion for the iliotibial band [65]. The pes anserinus is located medially and serves as the point of insertion for the sartorius, gracilis, and semitendinosus muscles [65]. The intercondylar eminence and medial and lateral tibial spines are nonarticular structures that separate the two plateaus [25]. The tibial spines serve as attachment points for the ACL anterior to the medial spine and the PCL extending to the posterior surface of the proximal tibia [25]. The proximal fibula buttresses the lateral plateau, and associated fractures of the proximal fibula result in greater valgus instability and indicate a more severe lateral fracture [25]. The proximal tibiofibular joint is a synovial joint that may communicate with the knee joint [25].

Soft Tissue & Neurovascular Anatomy¶

Both medial and lateral articular surfaces are covered by hyaline cartilage and partially covered by fibrocartilaginous menisci [25]. The menisci are attached to their respective plateaus by the menisci tibial ligaments (coronary ligaments) [25], with greater meniscal coverage of the lateral plateau than the medial plateau [25]. The common peroneal nerve runs under the cover of the biceps femoris and rests on the back of the neck of the fibula [25]. It is at risk from direct lateral impact mechanisms and with high-energy fractures, particularly medial plateau fractures which produce varus alignment [25]. The tibial nerve in the popliteal fossa is rarely injured and rarely part of surgical approaches for tibial plateau fractures [25]. The popliteal artery is rarely injured with tibial plateau fractures but is at risk in knee dislocations [25]. The trifurcation of the popliteal artery occurs in an area where plateau displacement is likely with certain fracture patterns [25]. The anterior tibial artery is bound at the interosseous membrane and is at particular risk in shaft-dissociated patterns [25].

The medial (tibial) collateral ligament inserts into the medial proximal tibia [65], while the lateral (fibular) collateral ligament inserts into the fibular head [65]. The ACL and PCL provide anterior-posterior stability [65]. The anterior compartment musculature attaches to the proximal lateral tibia [65]. The proximal medial tibial surface is devoid of muscle coverage but serves as an attachment point for the pes tendons [65]. The pes tendons, gracilis, sartorius, and semitendinosus insert on the anteromedial portion of the proximal tibia distal to the patellar tendon insertion [25]. The anterior compartment muscles, tibialis anterior, and extensor digitorum longus arise from the inferior surface of the lateral condyle of the tibia [25]. The medial head of the gastrocnemius arises from the posterior femur just above the posterior medial femoral condyle [25].

Mechanism of Injury¶

The magnitude, type, and direction of forces that injure the knee dictate the fracture pattern [2]. The greater the energy absorbed by the proximal tibia, the more severe the fracture and the more fragments are displaced and comminuted [2]. Axially loading forces are more rapid and release greater energy than angular forces [2]. In cadavers, pure valgus forces produce typical split fractures, axial forces produce local compression fractures, and combinations of both produce split depression fractures [2]. The intact medial collateral ligament (MCL) acts like a hinge for the lateral femoral condyle and must be present for the lateral plateau to fracture [2]. The proximal tibia is most likely to be subjected to a valgus force due to the normal 5 to 7 degrees of valgus alignment of the knee and a propensity to be struck from the lateral side [2]. A valgus force loads the lateral tibial plateau to failure from direct impact with the lateral femoral condyle [2].

Younger patients with good bone tend to have split fractures with less depression [2], whereas elderly patients with osteopenic bone have a greater component of compression with a less prominent split fragment [2]. In lateral fracture patterns, there is at least a small component of both a split fracture and depression at the peripheral margin of the fracture [2]. Varus injuries lead to failure of the medial plateau less commonly than lateral-side fractures [2]. Varus injuries can involve the entire medial plateau, and the fracture-shearing plane may extend well into the lateral plateau [2]. A posteromedial shearing fracture of the medial plateau is a common medial-side pattern [2], with a mechanism described as knee flexion, varus, and internal rotation of the medial femoral condyle [2]. Bicondylar patterns result when axial load predominates [2]. In a patient with a valgus knee, an axial force may shear the medial tibial condyle and produce a medial plateau fracture or fracture-dislocation [2].

Metaphyseal region fractures occur from direct trauma and/or a combination of axial load and bending forces [2]. These fractures involve the tibial shaft being separated from the condyles with proximal extensions of fracture lines into the plateau [2]. Metaphyseal region fractures have a high risk of complications including open fractures, severe closed soft tissue injury, trifurcation injury, and compartment syndrome [2]. Varus hyperextension injuries are associated with tension failure of the posterior cortex and compression of the anterior cortex with varus deformity in the coronal plane [2]. Fractures of the tibial plateau are caused by a varus or valgus force combined with axial loads, usually a fall from height [12]. One or both tibial condyles are crushed or split by the opposing femoral condyle, which usually remains intact [12]. Tibial plateau fractures result from direct axial compression—usually with a valgus (more common) or varus (less common) moment—and indirect shear forces [65]. The direction, magnitude, and location of the force as well as the position of the knee at impact determine the fracture pattern, location, and degree of displacement [65].

Tibial plateau fractures demonstrate distinct, mechanism-associated 3-dimensional pattern characteristics [4]. The impressive mechanisms of injury associated with tibial plateau fractures result in equally extensive injuries to the affected joint [7]. Fractures of the tibial plateau have been found to represent a broad category of high-energy and low-energy injuries [51]. Injury severity correlates to the tibial anatomy and the amount of energy delivered [51]. Tibial plateau fractures constitute 1% of all fractures and 8% of fractures in the elderly [24]. The incidence of tibial plateau fractures follows a bimodal distribution, primarily occurring in younger individuals due to higher energy mechanisms or elderly patients with osteoporotic bone following a low energy fall [24]. Historically, tibial plateau fractures were more common in young patients after high-energy trauma; now, a larger percentage results from a low-energy fall in older patients with osteoporotic bone [65].

In younger patients with more robust bone quality, the plateau is broken into various fragments after high-energy trauma, typified by more comminution and less joint line depression [17]. Trademarks of high-energy fractures include involvement of the medial plateau and the tibial spine and complete dissociation of the proximal tibial metaphysis [17]. In the elderly, low-energy mechanisms result in lateral plateau fractures with articular depression [17]. Split or wedge fractures occur in younger patients with stiffer bone, whereas depression fractures occur in older bone, which is less able to withstand compression [47]. High-energy proximal tibia injuries result in increased comminution and less predictable fracture patterns [47]. High-energy proximal tibia injuries are often associated with medial plateau involvement [47]. Isolated medial plateau injuries typify the higher level of damage associated with more severe mechanisms of injury [47]. Isolated medial plateau injuries typically involve both lateral collateral and anterior cruciate ligament injuries and can result in a fracture dislocation of the knee [47]. Isolated medial plateau injuries are more likely to have associated injuries of the popliteal artery and peroneal nerve [47]. The relative strength of the medial plateau, the valgus anatomic axis of the lower extremity, and the susceptibility of the leg to a medially directed force lead to a prevalence of lateral-side injuries in low-energy fractures [47].

Fractures of the medial tibial plateau make up 10–30 % of tibial plateau fractures [23]. Medial tibial plateau fractures typically occur due to a combined varus and axial force through the knee [23]. Medial tibial plateau fractures are often associated with subluxation or dislocation of the tibiofemoral joint [23]. Medial tibial plateau fracture-dislocation variants often occur with high energy mechanisms and have been associated with higher rates of complications including compartment syndrome and neurovascular injuries [23]. Concomitant meniscus and ligament tears are common in medial tibial plateau fractures [23]. Different angles of knee flexion under axial impact loading are possibly the interpretations for the two fracture patterns (split and depression) [136].

Associated Injuries¶

Patients with tibial plateau fractures frequently have associated injuries that may influence how the plateau fracture is managed [2]. In one study of bicondylar tibial plateau fractures, 13 of 41 patients had other major skeletal injuries in addition to the plateau fracture [2]. MCL injuries can be associated with lateral tibial plateau fractures [2]. Serious disruption of the stabilising structures of the knee are associated with relatively innocuous appearing marginal fractures of the tibial plateau [15]. The combination of shearing and compressive loads imparts a high risk of injury to the menisci, ligaments, peroneal nerve, and popliteus vessels [17]. The ubiquity and severity of soft-tissue damage related to these fractures have become more apparent and have affected the way these fractures are managed [17].

Meniscal tears are associated with up to 50% of tibial plateau fractures [65]. Associated injury to the cruciate or collateral ligaments occurs in up to 30% of patients [65]. Skin compromise is frequently present in high-energy fracture patterns [65]. In a review of 190 proximal tibial articular fractures, 67% of meniscal injuries occurred in plateau fracture patterns, whereas 96% of cruciate injuries and 85% of medial collateral ligament injuries occurred in fracture-dislocation patterns [33]. Peroneal nerve injury was twice as common in fracture-dislocation patterns [33]. Complex fractures involving the femoral and tibial surfaces had a 25% incidence of vascular injury and 25% incidence of compartment syndrome [33]. In 19 complex fractures with severe soft-tissue injury, vascular injury occurred in 31%, compartment syndrome in 31%, and peroneal nerve injury in 23% [33]. Ligamentous injuries occur more frequently in minimally displaced, local compression, and split compression fractures [33].

A 2005 series using MRI evaluation of surgical tibial plateau fractures found that the incidence of intracapsular soft-tissue injuries was almost universal, with lateral meniscus injury being the most common (91%) [56]. Ligamentous injury was noted in most fractures (77%) in the 2005 MRI series [56]. Intraoperative correlation has shown that only 30% of fractures have lateral meniscus tears that actually require surgical repair [56]. High-energy medial tibial plateau fractures commonly are accompanied by lateral collateral ligament and anterior cruciate ligament injuries [56]. Fractures of the tibial spine correlate to cruciate ligament dysfunction [56]. The rate of acute compartment syndrome in high-energy tibial plateau fractures requiring staged treatment has been reported to be as high as 27% [56]. Acute compartment syndrome disproportionately affects patients with medial plateau fracture-dislocations and concomitant vascular injuries [56]. Radiographic findings correlating to acute compartment syndrome include increased odds with Schatzker VI tibia plateau fractures, concomitant fibula fracture, and higher ratio of fracture length to tibia length [56]. Posterolateral tibial plateau fractures are associated with concomitant injuries to the anterolateral complex and both menisci [167]. Severe medial tibial plateau fractures are a challenge to the functional outcome of patients due to multiple concomitant injuries [41].

Classification¶

Schatzker Classification¶

Schatzker: Published in 1979 based on 94 lateral tibial plateau fractures collected between 1968 and 1975 [19]. This system classifies fractures into six types: * Type I: A pure cleavage or split fracture of the lateral tibial plateau forming a separate wedge-shaped fragment without articular crush, generally seen in young patients with good quality bone [19]. These fractures carry a high risk of ligamentous disruption and may be associated with meniscal trapping [75]. * Type II: A vertical split of the lateral condyle combined with central depression, where the lateral fragment is displaced laterally with widening of the joint [12]. * Type III: A depression of the articular surface with an intact condylar rim, usually resulting from lower-energy injury in older patients with a low risk of ligamentous damage [12, 75]. * Type IV: A fracture of the medial tibial condyle, presenting as a depressed crush fracture in osteoporotic bone or as a high-energy condylar split running obliquely from the intercondylar eminence to the medial cortex [12]. These are often high-energy injuries associated with peroneal nerve traction lesions [75]. * Type V: A fracture of both condyles where both are split but a column of the metaphysis remains in continuity with the tibial shaft, typically consisting of split fractures without articular depression [12, 75]. * Type VI: A combined condylar and subcondylar fracture where the tibial shaft is effectively disconnected from the tibial condyles, resulting from high-energy injury, often comminuted, and potentially associated with popliteal artery disruption [12, 75]. In traction of Type VI fractures, force tends to distract the metaphyseal-diaphyseal fracture rather than producing articular reduction [75].

The Schatzker system does not allow for further classification of medial tibial plateau fractures and does not take into consideration fracture dislocations or subluxations, which are common in medial injuries [23].

AO/OTA Classification¶

AO/OTA: This system is more comprehensive than the Schatzker classification and is commonly used in scientific publications [19]. It distinguishes between five primary fracture patterns and five fracture-dislocation patterns [33]: * Type 1: Minimally displaced fracture pattern [33]. * Type 2: Local compression fracture pattern [33]. * Type 3: Split compression fracture pattern [33]. * Type 4: Total condyle fracture pattern [33]. * Type 5: Bicondylar fracture pattern [33].

Fracture-dislocation patterns occur one seventh as frequently as pure fracture patterns [33]. The AO classification is more reliable between observers than the Schatzker classification for tibial plateau fractures seen on plain x-ray [60].

Limitations and Reliability¶

Both the AO and Schatzker classifications show limitations due to fracture complexity [60]. The Schatzker and OTA/AO classification systems are AP radiograph-based and fail to take into account bicondylar sagittal and/or coronal plane fracture lines and posterior shear fracture patterns [19]. Frequently used systems for classification of tibial plateau fractures display moderate intra and inter-observer reliability [98]. Agreement on classification is limited on 3DCT scan and is not improved by subtraction of unfractured bones [78]. CT scan is better than X-rays for analyzing and classifying tibial plateau fractures [84]. The use of 3D printing decreases measurement error and improves intraobserver and interobserver reliability [132], although the use of 3D-printed models is not recommended for classification [108]. Currently available classification systems may lead to frequent misclassifications [109].

Alternative and Extended Classifications¶

Hohl and Moore: This classification distinguishes between five primary fracture patterns and five fracture-dislocation patterns [33]. The Schatzker classification closely corresponds to the Hohl and Moore patterns with the addition of type VI, metaphyseal-diaphyseal dissociation [33].

Tscherne and Lobenhoffer: This classification assesses tibial plateau fractures on the basis of soft-tissue injuries [13].

Cotton and Berg: This was the first classification to take into account the mechanism by which the fracture occurred [13].

Three-Column Concept: This concept emphasizes the importance of CT imaging in the assessment of tibial plateau fractures [122]. An updated Three-Column Concept assessing fracture morphology and injury mechanism in tandem can be used to guide surgical treatment [77].

Four-Quadrant Classification: This system differentiates posteromedial and posterolateral tibial plateau fractures, which differ in mechanism, morphology, and surgical approaches [105].

Four-Column and Nine-Segment Classification: A novel system proposed as beneficial for clinical diagnosis, statistical analysis, and prognostic judgment [40].

Three-Dimensional Schatzker-Based System: A new classification utilizing computed tomography to define a virtual equator and quadrants for precise preoperative planning [116].

Segment Classification System: A detailed system that may delineate tibial plateau fractures more accurately when combined with knowledge of articular and non-articular area proportion [100].

Fracture Pattern Characteristics¶

Tibial plateau fracture maps show recurrent patterns of fracture lines, revealing four major fracture characteristics [3]. Split or cleavage depression fractures of the lateral plateau account for approximately 25-33% of all tibial plateau fractures [122]. The Schatzker and AO/OTA classifications identify Type II and Type 41-B3 fractures, respectively, as the most common type [122]. Fracture patterns 5 (involvement of the entire lateral plateau) and 7 (isolated lateral involvement) showed the lowest KOOS scores in lateral tibial plateau fractures [42]. Bicondylar type C fractures showed significantly greater losses in the Lysholm score [110], significantly greater pain levels on the VAS [110], and a significant reduction in the Tegner score compared to preinjury levels [110] when compared with type A or B fractures. Schatzker Type II fractures with a lateral split and a depression caused poorer results than isolated lateral split (Type I) or lateral depression (Type III) fractures [110].

Clinical Presentation¶

Mechanism of Injury¶

Tibial plateau fractures are intra-articular injuries that compromise knee alignment, stability, and movement [13]. If not treated effectively, they result in permanent deformity and disability [13]. The magnitude, type, and direction of applied forces dictate the resulting fracture pattern [2]. These injuries typically arise from varus or valgus forces combined with axial loads, often from falls from height [12, 24]. The incidence follows a bimodal distribution: younger individuals sustain high-energy injuries such as motor vehicle accidents, while elderly patients with osteoporotic bone suffer low-energy falls [24]. Men in their 30s and 40s are commonly affected, frequently due to motorcycle traffic accidents [67].

The mechanism of injury provides critical clues to the fracture pattern and directs vigilance for associated injuries [29]. Split lateral plateau fractures typically result from low-energy falls or twisting injuries [29]. Conversely, injuries from falls from height, motor vehicle accidents, or pedestrian strikes carry a much higher risk of associated neurovascular injury or compartment syndrome [29]. Relatively high-energy fractures can occur even when the history suggests innocuous mechanisms [29]. A posteromedial shearing fracture of the medial plateau is a common medial-side pattern, occurring either as an isolated split fracture or as part of a bicondylar pattern [2].

Physical Examination¶

Inspection reveals a swollen joint, potentially deformed with the doughy feel of haemarthrosis [12]. Hemarthrosis is typically present, though capsular disruption may cause extravasation into the surrounding soft-tissue envelope [65]. The soft-tissue envelope must be carefully examined, particularly when open reduction is planned, as its condition dictates surgical timing and approach [29]. Key features include the severity of swelling, visible contusions, and the size, character, and location of fracture blisters [29]. Normal skin wrinkling (positive wrinkle sign) suggests swelling has resolved [29]. Evaluation should also assess for edema, effusion, abrasions, and blisters [56]. Subtle findings may indicate severe injury, and high-energy mechanisms should heighten suspicion for soft-tissue damage [56]. Surfaces susceptible to open injury, such as the subcutaneous anteromedial proximal tibia, must be checked routinely [56].

Palpation over the site of potential fracture or ligamentous disruption elicits tenderness [65]. The neurovascular status of the limb must be assessed [56]. A normal pulse examination can be misleading, as pulses may remain normal despite vascular injury in up to 15% of cases [56]. Any asymmetry in pulses mandates an assessment of the ankle-brachial index (ABI) [56]. If the ABI is less than 0.9, further workup with conventional angiography, CT angiography, or duplex ultrasonography is warranted [56]. Failure to recognize vascular injury promptly is associated with a lower extremity amputation rate as high as 86% [56]. If pulses are not palpable, Doppler ultrasonographic studies should be performed [65]. An ABI less than 0.9 requires consultation with a vascular surgeon [65]. For high-energy injuries, a thorough vascular assessment with documentation of an ABI is advisable [29]. A normal ABI is greater than 0.9 [29]. If the ABI is less than 0.9, further vascular workup with a CT arteriogram may be necessary and a vascular consult is indicated [29].

Range-of-motion and stability assessments are limited by pain, which often makes it difficult to examine the knee for coronal instability [29]. Widening of the femoral-tibial articulation of more than 10° on varus or valgus stress examination, compared with the other leg, indicates instability [65]. In lateral tibial plateau fractures, assessing for valgus instability may guide the need for surgical treatment [29]. If valgus instability is present, it is likely caused by fracture displacement and will not resolve without reducing the fracture [29]. If the knee is subluxated, it should be reduced and the neurovascular examination repeated [65].

Red-flag patterns require mandatory thorough neurovascular examination, particularly in patients with certain fracture patterns [29]. Metaphyseal–diaphyseal dissociation patterns and fracture-dislocations are at particular risk for vascular or neurologic injury [29]. Certain types of tibial plateau fractures, especially medial tibial condyle fractures which are variants of knee dislocation, have a high risk for compartment syndrome [29]. The compartments of the lower leg should be evaluated with serial examinations for signs of compartment syndrome [29]. Presence of tense compartments and pain with passive stretching should raise suspicion of associated compartment syndrome [29]. Out-of-proportion pain is the most sensitive predictor of impending compartment syndrome [65]. The examiner should assess for pain out of proportion to the injury, pain on passive stretch of the toes, pallor, pulselessness, or impaired neurologic status [65]. Measuring compartment pressures is indicated in patients who are not responsive to clinical examination [29]. If the diagnosis of compartment syndrome is clear on physical examination, fasciotomy may be performed without pressure measurements [29]. Compartment pressures should be measured directly if the patient is unconscious and has a tense, swollen leg [65]. Patients with high-energy fracture patterns who are unable to provide a history or are difficult to examine may benefit from compartment pressures measured at presentation [29].

A neurologic examination to assess sensation and voluntary motor function is essential as a baseline and must be repeated periodically during the first day or two after injury [29]. Cutaneous sensation to tibial, superficial peroneal, saphenous, and sural nerves should be documented [29]. Serial clinical examination focused on swelling, motor function, sensation, and stretch pain is advisable because patients with intact arteries may develop compartment syndrome during the first few days after injury or surgery [29]. Younger age, high-energy mechanism of injury, and comminution have been associated with the development of acute compartment syndrome [56]. Increased odds of acute compartment syndrome are associated with Schatzker VI tibia plateau fractures, concomitant fibula fracture, and a higher ratio of fracture length to tibia length [56]. The presence of a non-contiguous tibia fracture or knee dislocation, and higher AO/OTA classification, are parameters related to the occurrence of acute compartment syndrome [73]. This study demonstrates a high rate of subjective instability following tibial plateau fractures [18].

Imaging¶

AP and lateral view X-rays are required, but the extent of comminution or depression is only fully appreciated on CT scan [12]. Plain radiographs should include a knee trauma series (AP, lateral, and oblique views) and a plateau view (10° caudal tilt) [65]. CT provides improved assessment of fracture pattern, aids in surgical planning, and improves the ability to classify fractures [65]. CT is very useful for surgical planning, particularly for the presence of a posterior condylar component which may require a separate posteromedial or postero-lateral exposure for fixation [12]. CT should be ordered when better visualization of bone fragments is required or to confirm a suspected traumatic arthrotomy (air in the open joint) [65]. MRI is of limited use in the acute setting [65]. Adequate and pertinent imaging including x-rays, computerized tomographic (CT) scans (with 3D reconstructions, if available), and MRI (if required) help to delineate the fracture pattern to make a surgical plan [38]. The most commonly used classification is that of Schatzker [12].

The major reasons for overlooking tibial plateau fractures were difficulty in recognizing them on X-rays and failure to employ X-ray decision rules [61]. Fractures of the posterior tibial plateau are not uncommon, especially in high-energy trauma [27]. Surgeons should be aware that medial articular impaction is present in approximately 8% of tibial plateau fractures [71].

Associated Injuries¶

Patients with tibial plateau fractures frequently have associated injuries, which may be other ipsilateral or contralateral skeletal injuries and injuries to other systems that may influence how the plateau fracture is managed [2]. In one study of bicondylar tibial plateau fractures, 13 of 41 patients had other major skeletal injuries in addition to the plateau fracture, and these associated injuries were found to affect the patients' functional outcome [2]. Tibial plateau fractures also have typical local soft tissue injuries that are important to recognize since they may influence fracture management and prognosis [2].

The combination of shearing and compressive loads imparts a high risk of injury to the menisci, ligaments, peroneal nerve, and popliteus vessels, not to mention the risk of skin damage [17]. Over the past decade, the ubiquity and severity of soft-tissue damage related to these fractures have become more apparent and have affected the way these fractures are managed, particularly in terms of surgical timing and the role of staged fixation [17]. In a 2005 series using MRI evaluation of surgical tibial plateau fractures, the incidence of intracapsular soft-tissue injuries was almost universal, with lateral meniscus injury being the most common (91%), and ligamentous injury was noted in most fractures (77%) [56]. High-energy medial tibial plateau fractures commonly are accompanied by lateral collateral ligament and anterior cruciate ligament injuries, which can result in a combined fracture-dislocation of the knee [56].

Proximal tibial articular fractures caused by high-energy mechanisms may be associated with neurologic and vascular injury, compartment syndrome, deep vein thrombosis, contusion, crush injury to the soft tissues, or open wounds [33]. Considering the “pure” fracture patterns, ligamentous injuries occur more frequently in minimally displaced, local compression, and split compression fractures [33]. It is wise to obtain stress radiographs of the knee to evaluate ligamentous structures in pure fracture patterns [33]. The presence of a tibial plateau fracture in conjunction with a ligamentous knee injury did not have a negative effect on postoperative patient-reported outcomes [44].

Investigations¶

Plain radiography: Plain radiographs provide substantial information and enable rapid assessment to differentiate high-energy from low-energy mechanisms of injury [115]. The AP knee radiograph should be tilted 7° to 10° caudal to match the posterior slope of the proximal tibia and accurately assess the articular surface [115]. The lateral view assesses for coronal fracture planes, and oblique views can also be insightful [115]. Contralateral AP and lateral knee radiographs should be obtained to assess for baseline coronal and sagittal plan alignment [107].

CT: CT with coronal and sagittal reconstructions is typically obtained for preoperative assessment [115]. The extent of comminution or depression is only fully appreciated on CT scan [12]. Three-dimensional CT is a more reliable radiographic modality than 2D CT in evaluation of fracture patterns in tibial plateau fractures [139]. Substantial improvements in interobserver and intraobserver reliability have been shown in determining the AO/OTA and Schatzker classifications when compared with two-dimensional CT [115]. However, the addition of 3D-CT reconstructions to the preoperative workup did not change management plans when compared to plans made using traditional CT-scans [153], and did not improve the reliability of CT-based evaluation of tibial plateau fractures [158]. CT may be delayed in cases of staged treatment of substantial comminution so that imaging may be conducted under ligamentotaxis after application of an external fixator [115].

MRI: MRI is not obtained routinely at most centers [115]. MRI can improve the early diagnosis of accompanying ligamentous and meniscal injuries [115] and enhance interobserver reliability when compared with two-dimensional CT [115]. MRI is generally recommended with respect to associated soft-tissue injuries, especially in cases with distinct tibial plateau fracture depression on multi-detector computed tomography scans [137].

Other Considerations: The preoperative plan requires careful evaluation of the injury radiographs and CT scan with or without three-dimensional reconstruction [107]. Both the AO and Schatzker classification systems show limitations due to fracture complexity [60]. The novel 'four-column and nine-segment' classification will be a beneficial classification system for clinical diagnosis, statistical analysis and prognostic judgment of tibial plateau fractures [40]. SWE can reliably and noninvasively detect high compartment pressure in tibial plateau fractures, providing superior diagnostic accuracy and clinical applicability [74].

Treatment¶

Non-Operative¶

Nonoperative management is indicated for undisplaced or minimally displaced tibial plateau fractures [1]. This includes small depressions of the lateral plateau without deformity or instability on clinical examination [1]. Significant medical comorbidities that preclude surgical treatment also mandate nonoperative care [1]. Elderly patients with low functional demands who tolerate subtle deformities are appropriate candidates for conservative treatment [1]. Fracture gaps or stepoffs up to 4 mm, as measured on CT images, can result in good functional outcome in patients treated nonoperatively [52]. No differences in patient-reported outcomes were seen at midterm follow-up when patients treated surgically and those treated nonsurgically for tibial plateau fractures with displacement up to 4 mm were compared [21]. Consequently, the arbitrary 2-mm limit of gaps and stepoffs for tibial plateau fractures should be revisited [111].

Undisplaced type 1 tibial plateau fractures can be treated conservatively with a hinged cast-brace or ROM brace to allow early mobilization [12]. Weight-bearing is restricted initially for conservatively treated undisplaced type 1 tibial plateau fractures [12]. Non-operative treatment focused on regaining mobility and function early rather than anatomical restitution is appropriate for stable type 2 fractures with depression less than 5 mm, or in low-demand patients or osteoporotic fractures [12]. Progressive incapacitating posttraumatic arthritis is very unusual in properly selected fractures treated nonoperatively [1].

Operative¶

Indications: Operative treatment is indicated for displaced unstable tibial plateau fractures where near-normal limb alignment cannot be predicted based on the fracture pattern or physical examination [53]. In young healthy patients, operative treatment includes almost all bicondylar and shaft dissociated patterns [53]. It also includes all but minimally displaced medial plateau fractures and lateral plateau fracture patterns where valgus alignment or instability will occur without surgical reduction and fixation [53]. The presence of a split fragment, a depression affecting over half of the lateral articular surface, a fibular head fracture, valgus alignment on injury radiographs, and clinical valgus alignment on examination are strong indications for surgery in lateral patterns [53]. Open reduction with elevation of the plateau and internal fixation is required for type 2 fractures that are not stable, have depression greater than 5 mm, or are in high-demand patients with non-osteoporotic bone [12]. Total knee arthroplasty holds promise as a primary treatment for tibial plateau fractures in older persons with osteoporotic bone, offering immediate stability, early mobilization, and decreased reoperation rates [119].

Surgical Approach / Technique: The overall goal of treatment is to promote fracture healing in a manner that allows the return of knee function with good motion while eliminating residual pain or instability [95]. Articular reduction remains the guiding principle for surgical indications and surgical approaches because tibial plateau articular defects affect the biomechanics of the knee joint [95]. Joint stability and axial alignment have been established as important prognostic indicators for tibial plateau fractures [95]. Restoration of mechanical axis and articular congruence are important in achieving a good clinical outcome for medial tibial plateau fractures [46]. The fracture pattern dictates the treatment plan and the risk for complications [19].

The Schatzker classification system is easier to remember, but the OTA/AO system is more comprehensive and commonly used in scientific publications [19]. AP radiograph-based classification systems fail to take into account bicondylar sagittal and/or coronal plane fracture lines and posterior shear fracture patterns, identification of which is paramount for adequate surgical planning [19]. Emphasis on anatomic and stable reduction of posterior condylar involvement has led to the importance of using descriptive terms from the three-column concept [19].

Joint surface inspection via submeniscal arthrotomy or arthroscopically is recommended for type 2 fractures requiring open reduction [12]. Impacted fragments should be elevated with an osteotome or bone tamp [143]. Isolated depression fragments require an osteotomy [143]. To preserve mechanical alignment, the metaphyseal-diaphyseal relationship should be reestablished, often using a combination of traction, reduction tool placement, and indirect plate reduction [143]. After the joint is reestablished and pinned into place with Kirschner wires, the articular reconstruction can be supported using the rafting screw concept [143].

A posterior reversed L-shaped approach can be recommended as a routine approach for the treatment of tibial plateau fractures involving the posterior column [104]. A posterior inverted L-shaped approach is a safe and effective way for the treatment of posterior bicondylar tibial plateau fractures [113]. Arthroscopic-assisted reduction and internal fixation (ARIF) is a reliable, effective, and safe method for the treatment of tibial plateau fractures, especially when they present with concomitant injuries [72]. ARIF holds promise as a superior technique compared to ORIF for managing tibial plateau fractures, offering enhanced visualization, more accurate reduction, and potentially faster postoperative recovery [124]. Complex tibial plateau fractures could be treated successfully using arthroscopy-assisted reduction and internal fixation, with most patients achieving excellent and good clinical outcomes and low complication rates [128]. ARIF has its place in the treatment of tibial plateau subsidence and/or separation fracture [89]. Arthroscopic surgery for tibial plateau fractures with associated soft-tissue injuries is a safe, reproducible, and effective procedure that provides precise diagnosis and effective treatment in a 1-stage procedure [135]. Arthroscopy-assisted management of Schatzker type III lateral tibial plateau fracture with interference screw fixation causes less soft-tissue trauma than other techniques and allows for fast patient mobilization and recovery [151].

Implant Selection: Partially threaded 6.5-mm screws work well for major plateau fracture lines, although smaller screws may work equally well [54]. 3.5-mm implants and screws are the most common size for anterolateral plates, having largely supplanted 4.5-mm implants [54]. Multiple holes in the head of the plate allow 3.5-mm screws to be placed parallel and close to the articular surface to support the reduced articular surface and minimize postoperative settling [54]. This technique of placing screws parallel to the articular surface has been termed “rafting screws” [54]. Screws can be placed in parallel just beneath the subchondral bone ('raft' screws) to support the articular surface in type 2 fractures [12].

Posteromedial plates must function as an antiglide device to resist shearing forces [54]. Plate constructs for bicondylar and Schatzker type VI patterns may be bigger (e.g., 4.5 mm) than those used for unicondylar fractures based on the need to resist substantial deforming forces [54]. Lateral plates must prevent the tendency of bending forces to create a varus deformity [54]. Lateral plates are generally considered insufficient in providing support for an unstable medial column [54]. Unicondylar fractures in healthy bone generally should be managed with nonlocked buttress plate fixation [143]. The wedge of the lateral condyle in type 2 fractures is fixed with a buttress plate [12].

Biomechanical evaluation using cadavers showed that the use of posterolateral rim plating in addition to lateral precontoured plates significantly increased area of articular support [143]. Biomechanical evaluation has shown that, for bicondylar fractures involving a posteromedial fragment, combining a lateral nonlocked plate with a posteromedial buttress plate is superior to the lateral locking plate with a higher load to failure [143]. Multiple clinical comparisons have reported that lateral locked plating for medial fractures is related to varus failure and articular subsidence [143]. One author advocates for performing posteromedial fixation first to provide a stable medial column to which the lateral plateau can be reduced and fixed [143].

Adjuncts: Bone graft may help support the articular surface in type 2 fractures [12]. It is beneficial to use porous titanium granules than autograft bone to fill the void created by reducing a depressed fracture of the lateral tibial plateau [62]. The treatment of depressed tibial plateau fractures with a calcium phosphate cement provides equivalent or better stability than conventional open reduction and internal fixation in pure depression tibial plateau fractures [127]. Calcium-phosphate synthetic bone grafts provided suitable mechanical support as part of the surgical treatment of tibial plateau fractures [150].

The LISS system could be considered for the management of tibial plateau fractures [63]. Percutaneous plating of low energy unstable tibial plateau fractures is a novel method of internal fixation that can be safely practised by an orthopaedic surgeon at a District General Hospital [112]. Intraoperative 3D imaging leads to a substantial revision rate in management of tibial plateau fractures, revealing indications for a limited analysis of fracture reduction and implant placement during operative treatment using conventional fluoroscopy [55]. Both intravenous and topical tranexamic acid regimens are safe and effective for reducing blood loss in complex tibial plateau fracture surgery [106].

Other Considerations: Modern locking plates have improved outcomes after proximal tibia fractures, but a high percentage of fractures still fail secondarily after fixation [19]. Secondary failure of fixation is mostly related to plates applied medially or laterally failing to adequately buttress the posterior plateau fracture fragment [19]. Fixation of hyperextension varus bicondylar tibia plateau fractures is performed through posteromedial and anterolateral surgical approaches [143]. The posteromedial approach can be used to reduce the posterior tension failure in hyperextension varus fractures [143]. The anterior metaphysis in hyperextension varus fractures can be disimpacted, the articular segment reduced, and void filled with bone graft or a substitute, with subsequent placement of an anteromedial-based buttress plate [143]. A laterally based plate can be used to maintain the coronal plane reduction in hyperextension varus fractures [143].

Postoperative Management: Early knee movement is encouraged after surgical treatment of type 2 fractures to minimize joint stiffness [12]. Patient function continues to improve over the first five years following tibial plateau fracture managed by open reduction and internal fixation [8]. Clinical outcome in tibial plateau fractures improves over time [114]. Early weight bearing (EWB) can be considered safe and effective in selected cases after internal fixation for tibial plateau fractures [79]. Weight bearing as tolerated does not negatively affect the results of tibial plateau fracture and may therefore be safe for postoperative management [91]. Further research is required to understand the stability of tibial plateau fractures and quantify whether patients can be allowed to weight bear earlier safely [85]. Consensus about the weight bearing aftercare for tibial plateau fractures is limited, with a large majority of surgeons not following the AO guideline or their own local protocol [130]. More transparent criteria and predictors are needed to design optimal weight bearing regimes for the aftercare of tibial plateau fractures [130]. There is no statistically significant difference between bracing and no bracing after open reduction and internal fixation of tibial plateau fractures in terms of functional, subjective, and radiographic outcomes [146]. Gait limitations in patients with intra-articular tibial plateau fractures are mainly related to the inability to extend the knee [16]. Operative treatment of tibia plateau fractures is a good option [30].

Complications¶

Infection and Wound Complications: Infection is the most common complication following operative fixation of tibial plateau fractures [24]. Prolonged operative time is associated with an increased infection rate [37]. High-energy tibial plateau fractures carry a significant risk of soft tissue complications resulting from surgical approaches [29].

Neurovascular and Compartment Syndrome: Medial tibial condyle fractures, which are variants of a knee dislocation, have a high risk for compartment syndrome [29]. This condition can result from muscle ischemia due to vascular obstruction (intimal injury and subsequent thrombosis) or secondary to hemorrhage due to shearing of the arteries [29]. Patients with tibial plateau fractures and intact arteries may develop compartment syndrome during the first few days after injury or surgery [29].

Mechanical Failure and Malalignment: Decreased knee stability and failure to restore joint alignment are the most significant factors that lead to poor long-term outcomes [24]. Angular malalignment after a tibial plateau fracture causes more loading of the articular cartilage of the injured condyle [1]. Malalignment may be cosmetically unacceptable, increases the propensity for knee instability, and can cause balance issues leading to falls [1]. Most plates applied medially or laterally fail to adequately buttress the posterior plateau fracture fragment, contributing to secondary failure after fixation [19]. Postoperative subsidence is associated with osteoporosis and osteopenia in patients above the age of 50 years with surgically treated low-energy tibial plateau fractures [142]. Inadequate experience of the surgeon, inaccurate diagnosis and management, improper selection of implants, and poor surgical techniques are common reasons for the failure of primary surgery in complex tibial plateau fractures [5].

Functional Limitations and Long-Term Outcomes: Patients with a proximal tibial plateau fracture have a higher cumulative risk of death during the mean 13.9-year observational period compared to an age- and gender-matched reference population [93]. Long-term deviations in gait and quality of life exist in patients following tibial plateau fracture [81]. A high rate of subjective instability is observed following tibial plateau fractures [18]. Total knee arthroplasty undertaken after fracture of the tibial plateau has a higher rate of complications than that undertaken for primary osteoarthritis [126]. In geriatric tibial plateau fractures, fracture morphology and surgical complexity are the main factors associated with complications [69]. Fewer than half of skiers who underwent operative fixation of a tibial plateau fracture could return to skiing at a mean 3-year follow-up [90].

Associated Injuries: Serious disruption of the stabilizing structures of the knee is associated with relatively innocuous appearing marginal fractures of the tibial plateau [15].

Recovery¶

Light activity (weeks): The provided evidence does not specify a typical week range for the resumption of desk work, driving, or light activities of daily living.

Full activity (months): The provided evidence does not specify a month range for the return to manual work, sport, or full range of motion and strength.

Complete recovery / outcome plateau (months): The provided evidence does not specify a month range for the stabilization of pain, strength, or final functional outcomes.

Rehabilitation protocol: The provided evidence does not detail specific physical therapy phasing, immobilisation duration, weight-bearing or range-of-motion progression schedules, or timing for sling or brace removal.

Functional milestones: Tibial plateau fractures decrease knee function compared with the contralateral side and preoperative conditions, with bicondylar fractures associated with worse functional outcomes [92]. The number of patients returning to recreational athletics gradually increased over time following operative fixation [96].

Other Considerations: In properly selected fractures, nonoperative treatment results in predictably excellent outcomes despite articular irregularities, and progressive incapacitating posttraumatic arthritis is very unusual [1]. Angular malalignment causes increased loading of the articular cartilage on the injured condyle, may be cosmetically unacceptable, increases the propensity for knee instability, and can cause balance issues leading to falls [1]. Older patients and those with more severe fractures are more likely to require total knee arthroplasty after repair [20]. Tibial plateau fractures are associated with poor functional outcomes and a low conversion rate to total knee arthroplasty [92]. Satisfactory results can be obtained in most carefully selected elderly patients with displaced fractures, provided meticulous surgical technique is observed and sufficient bone graft is used to prevent postoperative collapse of the elevated tibial plateau [11]. Early results of fracture stabilization with the proximal tibial LISS have been good, with excellent restoration of knee stability and motion and minimal soft tissue complications [35]. A postero-medial approach is a safe and practical method for treating complex tibial plateau fractures with postero-medial or postero-lateral shear fragments, yielding good outcomes [14].

[L3] EWB can be considered safe and effective in selected cases after internal fixation for tibial plateau fractures. [79] (10.1186/s13018-022-03156-8)
[L3] In particular, elderly patients without significant co-morbidities seem to be appropriate candidates for ORIF of their tibial plateau fractures. [80] (10.1007/s00264-018-3940-9)
[L3] Long-term deviations in gait and quality of life exist in patients following tibial plateau fracture. [81] (10.1007/s00402-015-2325-4)
[Paper] The commentary concludes that benefits of surgery for minimally displaced tibial plateau fractures (up to 4 mm displacement) were not observed at a mean of 6 years after surgery, suggesting a need for a careful reappraisal of indications for ORIF. [83] (10.1097/corr.0000000000003237)
[L3] CT scan is better than X-rays for analyzing and classifying tibial plateau fractures. [84] (10.1016/j.otsr.2013.06.007)
[L4] Further research is required to understand the stability of tibial plateau fractures and quantify whether we can allow patients to weight bear earlier safely. [85] (10.1016/j.injury.2025.112599)
[L5] It is proposed as an advancement over conventional methods for the reduction and internal fixation of depressed tibial plateau fractures, particularly in open surgical indications and rim depressions. [86] (10.1002/atn2.70046)
[L3] ARIF has its place in the treatment of tibial plateau subsidence and/or separation fracture. [89] (10.1016/j.otsr.2018.10.015)
[L4] Fewer than half of skiers who underwent operative fixation of a tibial plateau fracture could return to skiing at a mean 3-year follow-up. [90] (10.1177/23259671231205925)
[L4] Weight bearing as tolerated does not negatively affect the results of tibial plateau fracture and may therefore be safe for postoperative management. [91] (10.1016/j.injury.2017.05.024)
[L3] Tibial plateau fractures decrease the function of the knee when compared with the contralateral side and to the preoperative condition, with bicondylar fractures associated with worse functional outcomes. [92] (10.1002/ksa.12153)
[L3] Patients with a proximal tibial plateau fracture have a higher cumulative risk of death during the mean 13.9-year observational period compared to an age- and gender-matched reference population. [93] (10.1007/s00402-020-03408-4)
[L3] The number of patients who returned to participation in recreational athletics gradually increased over time after operative fixation of tibial plateau fractures. [96] (10.1177/2325967117743916)
[L1] Frequently used systems for classification of tibial plateau fractures display moderate intra and inter-observer reliability. [98] (10.1016/j.injury.2018.01.025)
[L5] The detailed segment classification system may delineate tibial plateau fractures more accurately; combined with knowledge of articular and non-articular area proportion, the fractured part can be calculated more precisely and proportionally, which is helpful in treatment decision making and preoperative planning. [100] (10.1016/j.injury.2019.01.021)
[L2] It can be recommended as a routine approach for the treatment of the tibial plateau fractures involving the posterior column. [104] (10.1016/j.injury.2015.05.005)
[L5] The four-quadrant classification differentiates posteromedial and posterolateral tibial plateau fractures, which differ in mechanism, morphology, and surgical approaches, providing a useful framework for operative planning. [105] (10.1007/s00264-017-3733-6)
[L3] Both intravenous and topical tranexamic acid regimens are safe and effective for reducing blood loss in complex tibial plateau fracture surgery. [106] (10.1186/s12891-020-03772-7)
[L3] Therefore, we cannot recommend the use of 3D-printed models in practice and research for classification of tibial plateau fractures. [108] (10.1097/corr.0000000000002137)
[L5] The use of 3D-printed models may not be helpful for education and/or preoperative planning in the context of tibial plateau fractures, and currently available classification systems may lead to frequent misclassifications. [109] (10.1097/corr.0000000000002170)
[L4] [110] (10.1177/0363546512462564)
[L5] The arbitrary 2-mm limit of gaps and stepoffs for tibial plateau fractures should be revisited. [111] (10.1097/corr.0000000000002456)
[L4] This novel method of internal fixation could be a useful inclusion in the armamentarium for the management of tibial plateau fractures and can be safely practised by an orthopaedic surgeon at a District General Hospital. [112] (10.1016/s0020-1383(00)00118-2)
[L4] This approach is a safe and effective way for the treatment of posterior bicondylar tibial plateau fractures. [113] (10.1007/s00402-012-1632-2)
[L3] [114] (10.1016/j.injury.2025.112607)
[L5] The authors propose a new three-dimensional classification system for tibial plateau fractures based on the Schatzker classification, utilizing computed tomography to define a virtual equator and quadrants for precise preoperative planning of surgical approach and hardware application. [116] (10.1016/j.injury.2018.11.010)
[L4] Total knee arthroplasty holds promise as a primary treatment for tibial plateau fractures in older persons with osteoporotic bone, offering immediate stability, early mobilization, and decreased reoperation rates. [119] (10.5435/jaaos-d-16-00565)
[L3] [122] (10.1007/s00402-014-2131-4)
[L1] ARIF holds promise as a superior technique compared to ORIF for managing tibial plateau fractures, offering enhanced visualization, more accurate reduction, and potentially faster postoperative recovery. [124] (10.1177/2325967124s00411)
[L3] Total knee arthroplasty undertaken after fracture of the tibial plateau has a higher rate of complications than that undertaken for primary osteoarthritis, but patient-reported outcomes and satisfaction are comparable. [126] (10.1302/0301-620x.97b4.34789)
[L5] The treatment of depressed tibial plateau fractures with a calcium phosphate cement provides equivalent or better stability than conventional open reduction and internal fixation in pure depression tibial plateau fractures. [127] (10.1097/00005131-200103000-00009)
[L3] Complex tibial plateau fractures could be treated successfully using arthroscopy-assisted reduction and internal fixation, with most patients achieving excellent and good clinical outcomes and low complication rates. [128] (10.1186/s13018-023-03938-8)
[L4] [130] (10.1007/s00402-017-2718-7)
[L4] The use of 3D printing decreases measurement error and improves intraobserver and interobserver reliability in the classification of tibial plateau fractures. [132] (10.5435/jaaosglobal-d-22-00202)
[L4] Arthroscopic surgery for tibial plateau fractures with associated soft-tissue injuries is a safe, reproducible, and effective procedure that provides precise diagnosis and effective treatment in a 1-stage procedure. [135] (10.1016/j.arthro.2008.02.017)
[L4] Different angles of knee flexion under axial impact loading are possibly the interpretations for the two fracture patterns (split and depression). [136] (10.1007/s00402-014-2037-1)
[L4] Magnetic resonance imaging is generally recommended with respect to associated soft-tissue injuries, especially in cases with distinct tibial plateau fracture depression on multi-detector computed tomography scans. [137] (10.1007/s00167-012-2201-5)
[Paper] Three-dimensional CT is a more reliable radiographic modality than 2D CT in evaluation of fracture patterns in tibial plateau fractures. [139] (10.1016/j.injury.2009.02.015)
[L3] Osteoporosis and osteopenia were common in this selected cohort of DEXA-assessed patients above the age of 50 years with surgically treated low-energy tibial plateau fractures. [142] (10.1007/s00402-026-06528-5)
[L2] Our prospective study showed no statistically significant difference between bracing and no bracing after open reduction and internal fixation of tibial plateau fractures in terms of functional, subjective, and radiographic outcomes. [146] (10.5435/jaaos-d-16-00021)
[L4] Nevertheless, both provided suitable mechanical support as part of the surgical treatment of tibial plateau fractures. [150] (10.1016/j.injury.2017.10.030)
[Paper] The presented technique creates alternative possibilities in Schatzker type III tibial plateau fracture management, causing less soft-tissue trauma than other techniques and allowing for fast patient mobilization and recovery. [151] (10.1016/j.eats.2021.01.014)
[L4] The study demonstrates that the addition of 3D-CT reconstructions to the preoperative workup of tibial plateau fractures did not change management plans when compared to plans made using traditional CT-scans. [153] (10.1186/s12891-015-0608-0)
[L3] Furthermore, the addition of 3DCT reconstructions did not improve the reliability of CT-based evaluation of tibial plateau fractures. [158] (10.1016/j.injury.2015.12.022)
[L3] PLTFs are associated with concomitant injuries to the ALC and both menisci, indicating that they occur within a broader pattern of structural knee damage. [167] (10.1002/ksa.70393)
