Overview

Partial meniscectomy is indicated for nonobstructive meniscal tears, though its benefit is limited [1]. Determining the presence of osteoarthritis is necessary to establish indications for surgical versus nonsurgical treatment in these cases [1]. For traumatic meniscal tears in patients under 45 years, arthroscopic partial meniscectomy leads to a similar quality of life but higher costs compared to physical therapy plus optional delayed arthroscopic partial meniscectomy [32]. The procedure is also indicated for radial tears if conservative treatment fails [72] and for medial meniscal flap tears, which yield favorable 12-month outcomes [36]. In symptomatic discoid lateral meniscus, radiographic outcomes are better with partial than total meniscectomy, while clinical outcomes are similar [5].

Arthroscopic partial meniscectomy improved pain and function at the first year post-operatively [10]. A majority of patients achieved MCID, SCB, and PASS by 6 months [84], although proportions achieving these milestones decrease over time [84]. Meniscectomy offers a fast return to play with good short-term results [15]. However, the procedure generated significantly more cost than non-operative management ($3842.57 versus $411.05) [13] and was associated with higher rates of progression to knee arthroplasty compared to non-operative management [13]. Randomized clinical trials generally do not support the efficacy of arthroscopic partial meniscectomy for degenerative meniscal tears, particularly in patients with osteoarthritis [22]. There is currently no compelling evidence to support arthroscopic partial meniscectomy versus physical therapy for degenerative meniscus lesions [77].

The role of arthroscopic partial meniscectomy remains controversial [22], as some surgeons believe it provides dramatic pain relief for specific indications [22]. Preservation of the meniscus should be considered as the first line of treatment because of an inferior clinical and radiological long-term outcome after partial meniscectomy compared to meniscus repair [81]. Meniscal repairs are associated with better long-term outcomes than partial meniscectomies [83], though they have a higher reoperation rate [83]. In appropriately selected patients, meniscal repair can deliver improved subjective outcomes with comparable reoperation rates and the potential for reduced risk of osteoarthritis over time versus meniscectomy [41]. The long-term risk of osteoarthritis must be weighed when making patient selection for meniscectomy [15]. Partial meniscectomy for a complete medial meniscus posterior root tear provides no benefit in halting arthritic progression [2]. Meniscal replacements could not restore outcomes to native meniscus levels or sufficiently improve outcomes after meniscectomy [39].

Anatomy & Pathophysiology

Meniscal Anatomy and Structure

The menisci are C-shaped, wedge-shaped fibrocartilaginous disks situated between the femoral condyles and tibial plateau, providing shock absorption, increasing joint congruency, enhancing stability, and aiding synovial fluid distribution [46]. They possess a triangular cross section and consist of type I collagen fibers arranged obliquely, radially, and vertically [106]. The macrostructure comprises tibial attachments at the anterior and posterior roots, curved anterior and posterior horns, and the meniscal body at the midportion [102].

Medial Meniscus: The medial meniscus has a semicircular shape covering approximately 50% to 60% of the medial tibial plateau in adulthood [102]. It is firmly attached to the joint capsule along its entire peripheral edge, limiting mobility [46]. Peripherally, it attaches to the deep medial collateral ligament and joint capsule [102]. The posterior horn averages 11 mm in the anterior-posterior dimension, while the anterior horn is narrower [102]. The anterior horn attaches to the tibia anterior to the anterior cruciate ligament near the intercondylar fossa with significant variability [102]. The posterior root lies in the posterior intercondylar fossa between the lateral meniscus and posterior cruciate ligament [102]. The meniscotibial (coronary) ligament stabilizes the medial meniscus via attachment from the inferior aspect of the posterior horn to the tibia [102]. The posterior horn is linked to the posteromedial capsule, deep medial collateral ligament, posterior oblique ligament, and semimembranosus expansion [101]. It serves as a chock block on the tibial plateau, and its absence increases instability in both anterior cruciate ligament and posterior cruciate ligament deficient knees [101].

Lateral Meniscus: The lateral meniscus is larger than the medial meniscus and has a more circular C-shape with symmetric anterior and posterior horns [102]. It covers a larger proportion of the tibial plateau [106]. It is attached to the anterior and posterior capsule, but a region posterolaterally lacks firm attachment [46]. The anterior root attaches anterior to the intercondylar eminence and just lateral to the anterior cruciate ligament insertion site [102]. The posterior root attaches posterior to the lateral tibial spine just anterior to the medial meniscus posterior root [102]. The popliteomeniscal fascicles extend from the lateral meniscus to the posterior capsule to create the popliteal hiatus [102]. Meniscofemoral ligaments are variably present structures connecting the posterior horn of the lateral meniscus to the medial femoral condyle; the ligament of Humphrey crosses anterior to the posterior cruciate ligament, while the ligament of Wrisberg crosses posteriorly [102]. The less continuous attachment allows for greater mobility, with a mean excursion of 11.2 mm from extension to flexion compared to 5.1 mm for the medial meniscus [102]. The lateral meniscus carries a greater share of lateral compartment pressure than the medial meniscus carries for the medial compartment [46].

Vascular Zones: The menisci have three zones based on vasculature and extracellular matrix composition: white-white (ww), red-white (rw), and red-red (rr) [102]. The inner one-third is the avascular white-white zone [102]. The middle zone is the red-white zone with limited vasculature [102]. The back one-third is the red-red zone, the most vascularized region with blood supply from geniculate arteries [102]. Vascular supply derives from geniculate arteries, penetrating 20% to 30% of the peripheral medial meniscus and 10% to 25% of the peripheral lateral meniscus [106]. The transverse, or intermeniscal, ligament connects the anterior horns of the medial and lateral menisci [102]. The menisci are attached to collateral ligaments via coronary ligaments [106].

Bony Anatomy

The bones of the knee are the distal femur, proximal tibia, and patella [46]. The medial femoral condyle is larger and projects farther posteriorly and distally than the lateral condyle [91]. The lateral femoral condyle projects farther anteriorly and is wider in the medial-lateral direction [91]. The tibial articular surface slopes 7° to 10° in the sagittal plane [91]. The medial tibial plateau is larger than the lateral plateau and is concave in both frontal and sagittal planes [91]. The lateral tibial plateau is smaller, more circular, concave in the frontal plane, and convex in the sagittal plane [91]. The posterior slope of the medial tibial plateau averages 10.7°, while the lateral plateau averages 7.2° [106]. The medial compartment has a large surface area containing the convex femoral condyle and concave tibial plateau [106]. The lateral compartment has a smaller surface area containing the convex femoral condyle and convex lateral plateau in the sagittal plane [106]. Without menisci, convex femoral condyles articulate with relatively flat tibial plateaus, resulting in non-congruent joint surfaces [46]. Meniscal absence decreases contact surface area and increases pressure on articular cartilage, potentially leading to rapid joint surface deterioration [46].

Ligamentous Anatomy

The anterior cruciate ligament (ACL) travels from the medial border of the lateral femoral condyle to its insertion site anterolateral to the medial tibial spine [46]. It prevents anterior translation and rotation of the tibia on the femur [46]. The ACL is composed of 90% type I collagen and 10% type III collagen [91]. Its mean length is 33 mm and mean midsubstance width is 11 mm [91]. The femoral attachment is a semicircular area (20 mm long and 10 mm wide) on the posteromedial aspect of the lateral femoral condyle [91]. The tibial attachment is a broad, irregular, oval-shaped area (30 mm long and 10 mm wide) slightly medial and anterior to the midline, between the medial and lateral tibial spinous processes [91]. The anteromedial bundle is tight in knee flexion, while the posterolateral bundle is tight in knee extension [106]. The posterolateral bundle prevents the pivot-shift phenomenon and stabilizes against anterior translation with 30° of knee flexion [106]. The anteromedial bundle increases anterior tibial translation at 60° and 90° of knee flexion [106].

The posterior cruciate ligament (PCL) prevents posterior subluxation of the tibia on the femur [46]. It has a mean length of 38 mm and mean width of 13 mm [106]. The femoral attachment is broad and crescent-shaped on the anterolateral medial femoral condyle, with a mean length of 30 mm and mean width of 5 mm [106]. The tibial insertion onto the posterior central sulcus is 10 to 15 mm distal to the joint line [106]. The anterolateral bundle is stronger and stiffer than the posteromedial bundle and is tight in knee flexion, while the posteromedial bundle is tight in knee extension [106].

The medial collateral ligament has superficial and deep portions stabilizing the knee against valgus stresses [46]. The lateral collateral or fibular collateral ligament runs from the lateral femoral condyle to the head of the fibula and is the main stabilizer against varus stress [46]. The popliteofibular ligament is present in 90% of knees and runs from the popliteus tendon to the styloid on the posterior fibular head [46]. The joint capsule and collateral ligaments are the principal extraarticular static stabilizing structures [94]. The menisci attach firmly at the periphery to the joint capsule, especially medially and less so laterally [94]. Laterally, the popliteal tendon passage through the popliteal hiatus produces a less secure meniscal attachment than medially [94]. The medial capsule is more distinct and well-defined than its lateral counterpart [94].

The posteromedial corner of the knee has five major components: the posterior oblique ligament, the semimembranosus tendon and its expansions, the oblique popliteal ligament, the posteromedial joint capsule, and the posterior horn of the medial meniscus [101]. The posterior oblique ligament is a thickening of the medial capsular ligament attached proximally to the adductor tubercle of the femur and distally to the tibia and posterior aspect of the capsule [101]. The posteromedial capsule and posterior oblique ligament become progressively relaxed as the knee flexes, but with active contraction of the semimembranosus muscle, each of the three arms of the posterior oblique ligament is tense [101]. The posteromedial portion of the medial capsular ligamentous complex is especially important for valgus and rotational stability [101].

Vascular and Nerve Anatomy

The blood supply to the knee forms an anastomosis around the knee derived from the descending geniculate artery, medial and lateral superior geniculate arteries, medial and lateral inferior geniculate arteries, middle geniculate artery, and anterior tibial recurrent arteries [91]. The middle geniculate artery supplies both the anterior and posterior cruciate ligaments [91]. The inferior geniculate arteries pass deep to their respective collateral ligaments [91]. The blood supply of the patella derives from the geniculate artery complex with some contribution from the anterior tibial recurrent artery, primarily existing in the middle to inferior portions of the patella [91].

The knee is innervated by branches of the femoral nerve (L2, L3, L4), obturator nerve (L2, L3, L4), and sciatic nerve (L4, L5, S1, S2) [91]. The largest nerve providing innervation of the intra-articular knee is the posterior articular branch of the tibial nerve [91]. This branch supplies the infrapatellar fat pad, the synovial covering over the cruciate ligaments, and the periphery of the meniscus [91]. Nerves to the cruciate ligaments contain vasomotor and pain fibers as well as mechanoreceptors that may be involved in proprioception [91]. The infrapatellar branch of the saphenous nerve arises proximal to the knee joint medially and crosses distal to the patella to innervate the skin over the region of the anterior knee and proximal tibia [91].

Biomechanics and Pathophysiology

The primary function of the meniscus is to redistribute forces across the tibiofemoral articulation, decreasing contact pressure and resultant stress on articular cartilage [88]. Menisci play a secondary role in stabilizing the knee and a possible role in joint lubrication [88]. They help with load transmission and bear one-third to one-half body weight [107]. Removal of the menisci increases contact stresses, with up to four times the load transfer to bone [107]. As the portion of the meniscus removed increases, greater contact pressures are experienced by the cartilage, leading to altered knee mechanics [16]. Meniscectomy alters stress distribution, decreases contact area, and increases contact pressure between femur and tibia; these alterations are more pronounced in the lateral than in the medial compartment [177].

Meniscal root tears are frequently unrecognized injuries that significantly alter knee biomechanics and kinematics, leading to accelerated degenerative changes [25]. The integrity of the posterior root of the medial meniscus plays an important role in maintaining normal tibial-femoral joint contact mechanics [73]. Decreased displacement of the medial meniscus after partial medial meniscectomy may explain higher pressure on knee components, indicating potential biomechanical risk of knee degeneration [125]. Meniscal injury negatively affects knee biology within a very short period, with degenerative changes of articular cartilage becoming apparent within a decade [161]. Once meniscal functions such as distributing load, delivering congruency, enhancing stability, and contributing to lubrication and nutrition are impaired, chondroprotection is disrupted, increasing the risk of degenerative change and increased morbidity [209]. Findings of increased osteoarthritis associated with meniscus injury may be explained by decreased stability and altered contact mechanics after partial or total meniscectomy [210]. The decreased tibiofemoral joint space associated with meniscectomy can change the relationship of the patellar to the femoral trochlea, causing patellofemoral cartilage degeneration [210].

Synovitis contributes to osteoarthritis progression through the upregulation of pro-inflammatory cytokines such as interleukin-1β and tumour necrosis factor-α, as well as matrix-degrading enzymes like matrix metalloproteinases [226]. Meniscal tears are a known risk factor for osteoarthritis and may initiate or amplify synovial inflammation, even in the absence of radiographic osteoarthritis [226]. Intraoperative and histological studies have reported synovitis in up to half of patients undergoing arthroscopic partial meniscectomy, correlating with worse baseline symptoms and potentially mediating cartilage loss and osteoarthritis progression [226].

The meniscus status has a significant impact on knee kinematics in the anterior cruciate ligament-deficient knee [124]. A longitudinal tear of the medial meniscus posterior horn in an anterior cruciate ligament-deficient knee alters knee kinematics, particularly the anterior-posterior tibial translation [151]. The biomechanical consequences of a lateral meniscus root tear depend on the state of the meniscofemoral ligament [154]. Forces at the anterior meniscus attachments strongly increase under dynamic knee joint loading [132]. In vitro tests applying uniaxial loads combined with static knee flexion angles or very low flexion-extension speeds appear to underestimate meniscus attachment forces [132]. Motion and weight loading of the knee can generate considerable tensile forces in repaired posterior medial meniscal roots [141].

Classification

Indications and First-Line Management: Arthroscopic partial meniscectomy should not be proposed as a first-line treatment for degenerative meniscus lesions; non-operative treatment should always be started first, with surgery only envisaged after its failure [29]. Knee partial meniscectomy has limited benefit for nonobstructive meniscal tears, but it is necessary to determine if included patients have osteoarthritis to establish indications for surgical versus nonsurgical treatment [1]. Medial meniscal tears pose a more challenging dilemma where partial meniscectomy must be balanced against long-term degenerative consequences, and many tears are correctly treated non-operatively [68].

Comparative Outcomes and Long-Term Consequences: Meniscus root repair leads to significantly less arthritis progression and subsequent knee arthroplasty compared with nonoperative management and partial meniscectomy in a matched cohort based on patient characteristics [45]. In complete-type discoid meniscus, total meniscectomy showed better short-term clinical results, but partial meniscectomy showed better long-term radiological results, while partial meniscectomy was superior for incomplete types [38]. Radiographic outcomes are better with partial meniscectomy than with total meniscectomy for symptomatic discoid lateral meniscus, but clinical outcomes are similar [5]. Although there were no differences in clinical results between the partial and subtotal/total meniscectomy groups, partial meniscectomy yielded better radiologic results than subtotal/total meniscectomy for torn discoid lateral menisci in children [40]. Partial medial meniscectomy, as an isolated factor, does not appear to have the deleterious effect reported with total meniscectomy [12]. Partial medial meniscectomy in stable knees causes only mild joint space narrowing (mean, 1.2 mm) at a mean 12-year follow-up [9].

Cartilage and Osteoarthritis Progression: Arthroscopic partial medial meniscectomy is associated with adverse effects on articular cartilage and may lead to an increase in the severity and size of cartilage lesions [31]. Simultaneous partial meniscectomy did not decrease knee function further; instead, the meniscal injury and surgery caused a higher degree of osteoarthritis in knees with localized, severe chondral damage [6]. Partial meniscectomy was found to be strongly associated with the progression of articular cartilage damage despite anatomical anterior cruciate ligament reconstruction [90]. Meniscal repair is associated with a lower progression to knee osteoarthritis at approximately six years of followup compared to partial meniscectomy [24]. Arthroscopic partial meniscectomy generated significantly more cost than non-operative management ($3842.57 versus $411.05) and was associated with higher rates of progression to knee arthroplasty [13]. Partial meniscectomy adversely affects return-to-sport outcome after anatomical double-bundle anterior cruciate ligament reconstruction [7]. Secondary tears often present as complex tears of the medial meniscus and result in high rates of partial meniscectomy in patients with anterior cruciate ligament injury [30].

Prognostic Factors and Biomechanics: Patients with grade II, III, or IV chondromalacia had a higher rate of unsatisfactory results (33%) compared with patients with less than grade II chondromalacia (9%) after isolated arthroscopic partial meniscectomy [26]. Radiographic evidence of abnormal stress transfer to articular cartilage and subchondral bone as evidenced by Fairbank’s changes was seen after arthroscopic partial meniscectomy [26]. Articular cartilage and meniscus exhibit molecular events associated with osteoarthritis at the time of partial meniscectomy despite no gross evidence of degeneration in the knee [206]. The lateral compartment appears to be at greater risk for full-thickness cartilage loss, and previous knee surgery, particularly meniscectomy, is associated with these lesions [11]. Partial meniscectomy significantly alters the loading situation of the meniscus and its attachments [82]. Total medial meniscectomy leads to significantly worsened load distribution within the knee [44]. These results suggest both a structural element and a potential muscular element for the differences in kinematics after partial medial meniscectomy and highlight the importance of challenging the knee with activities of increased demands to detect differences in kinematics from the contralateral limb [54].

Other Considerations: In a consecutive series of 291 arthroscopic partial meniscectomies, 84% of patients with meniscal damage only were symptomatically cured by their arthroscopic operation [8]. In a consecutive series of 291 arthroscopic partial meniscectomies, 6% of patients with meniscal damage only had arthroscopic partial meniscectomy that either failed to give any symptomatic improvement at all or resulted in only short-term relief [8]. Meniscal allograft transplantation may result in important pain relief and functional improvement in patients with a history of (sub)total meniscectomy and pain localized in the affected compartment [4]. These findings allow researchers and clinicians to determine whether partial meniscectomy is meaningful to patients at the individual level and will be helpful for responder analysis in future trials related to the treatment of meniscal abnormality [21]. Statistically derived formulae can be used to predict the outcome of one knee scoring system when the result of another is known in patients with meniscal tears before and after arthroscopic meniscectomy [181]. This international EU–US consensus established recommendations for prevention strategies, describes rehabilitation of non-operated patients and of patients after partial meniscectomy, meniscus repair and meniscus reconstruction, and establishes return to sport criteria [33].

Clinical Presentation

Mechanical symptoms attributable to a torn meniscus, such as locking, effusion, pain, and instability, are indications for surgical intervention when nonsurgical treatment fails [50]. In a prospective study of patients with meniscal tears, inclusion criteria required pain over the joint line during weightbearing and/or mechanical symptoms such as locking episodes or a "pop" or "clunk" sensation [143]. A history of "locking" of the knee was reported by 44.0% of patients in a retrospective series of arthroscopic medial meniscectomies [61]. Over half of patients undergoing arthroscopic partial meniscectomy report preoperative pain at night [70].

Meniscal tears are relatively common in asymptomatic knees, with 36% of healthy volunteers older than age 45 years having meniscal tears by MRI [50]. In a study of healthy volunteers with no knee symptoms, 13% of those younger than age 45 years had meniscal tears by MRI [50]. In a study of symptomatic knees, 91% had meniscal tears by MRI, while 76% of matched control knees also had tears [50]. In a study of patients aged 18 to 73 years, 57 of 100 symptomatic knees were diagnosed with meniscal tear by MRI, while 36 of the 100 contralateral asymptomatic knees also had tears [50].

Patients with the "comma sign" on imaging present with a decreased duration of symptoms compared to control groups [136]. Patients with the "comma sign" present with greater levels of arthritis, measured by Kellgren-Lawrence score, compared to control groups [136]. Meniscal root tears are frequently unrecognized injuries that significantly alter knee biomechanics and kinematics [25]. Secondary meniscal tears often present as complex tears of the medial meniscus [30].

Post-meniscectomy pain syndrome and post-meniscectomy knee osteoarthritis are common findings after meniscus resection [65]. In symptomatic patients after arthroscopic partial meniscectomy for discoid lateral meniscus, the thickness and width of the residual meniscus decreases over time [75]. In symptomatic patients after arthroscopic partial meniscectomy for discoid lateral meniscus, arthritic change of the lateral compartment of the knee progresses [75].

Investigations

Plain radiography: Plain radiographs serve as the appropriate initial imaging study for most knee conditions, allowing assessment of traumatic injury, arthritis, patellofemoral alignment, osteochondral injury, bone neoplasm, and surgical implants [111]. For articular cartilage evaluation, review weight-bearing AP and lateral views and an axial view of the patellofemoral joint; a semiflexed PA view may improve detection of subtle narrowing or isolated chondral defects on the flexion surface [115]. Radiographs remain the standard for initial evaluation of knee arthritis, including weight-bearing AP and lateral views, a view of the weight-bearing knee flexed at 45-degree angle, a sunrise view, extension and flexion lateral views, and a standing full-length AP radiograph [120]. Long leg alignment views determine the mechanical axis; if this axis traverses the involved compartment, realignment may be considered as an initial procedure or adjunct to cartilage restoration [115]. While radiographs can underestimate isolated chondral lesions, they may demonstrate joint space narrowing, osteophytes, sclerosis, and cysts [115]. Digital radiographic evaluation of medial joint space narrowing after partial meniscectomy of bucket-handle medial meniscus tears in anterior cruciate ligament–intact knees shows only mild narrowing (mean, 1.2 mm) at a mean 12-year follow-up [9]. Partial medial meniscectomy, as an isolated factor, does not appear to have the deleterious effect reported with total meniscectomy regarding joint space narrowing [12]. Radiographic signs of osteoarthritis are significant at 8 to 16 years' follow-up after knee arthroscopic partial meniscectomy, but clinical symptoms of knee arthritis are not significant [55]. In children with torn discoid lateral menisci, partial meniscectomy yields better radiologic results than subtotal or total meniscectomy, despite no differences in clinical results [40]. Progression of radiographic osteoarthritis after partial meniscectomy in degenerative medial meniscal posterior root tears is greater in varus- than in neutral-aligned knees at a minimum 5-year follow-up [69].

MRI: MRI provides an accurate depiction of knee anatomy and pathology and is widely accepted as a critical tool for clinical evaluation [89]. Its diagnostic validity for meniscal tears is similar in acute knee trauma and in knee symptoms lasting over 6 months in young adults [212]. MRI is useful for confirming suspected MCL injury, identifying the site of injury, and detecting meniscal and other knee injuries [98]. It also serves as a useful adjunct for diagnosing suspected LCL or posterolateral corner injuries [121]. MRI can evaluate articular cartilage morphology [115]. However, MRI is not always useful in predicting reparability of symptomatic isolated lateral semilunar meniscus tears, as most symptomatic cases with normal MRI were reparable [207]. A supplementary MRI increases diagnostic accuracy when fewer than three clinical findings are present in a symptomatic meniscal repair patient [201]. In the arthritic population, MRI is grossly overused and is not indicated if the joint space is significantly narrowed on radiograph, but is used when osteonecrosis is suspected [120]. MRI of the symptomatic knee after meniscal surgery is a valuable diagnostic study; for partial meniscectomy of less than 25%, MRI is sufficient, whereas for greater than 25% resection or after repair, direct or indirect MRA should be considered [63]. In symptomatic patients after arthroscopic partial meniscectomy for discoid lateral meniscus, MRI findings show that the thickness and width of the residual meniscus decreases over time and arthritic change of the lateral compartment progresses [75]. Patients with femoral bone marrow lesions are more likely to gain benefit from arthroscopic partial meniscectomy in the middle term [87]. Conversely, chondral lesions at the medial femoral condyle, meniscal degeneration, anterior cruciate ligament insufficiency, and lateral meniscal tears impair middle-term results after arthroscopic partial meniscectomy [87]. Arthroscopic repair of isolated medial degenerative meniscus tears in patients over 45 years resulted in good to excellent clinical outcomes with low clinical failure rates, despite unhealed menisci being observed on MRI in 41% of patients [218].

CT: Three-dimensional CT with remodeling is used for preoperative planning for reconstruction associated with dysplasia, post-trauma planning, and complex total knee arthroplasty planning [120].

Other Considerations: Ipsilateral chondral lesions worsen the long-term prognosis following arthroscopic partial medial meniscectomy, with patients having concurrent focal cartilage defect in the medial compartment showing clinically and radiologically worse outcomes than patients without any cartilage defect at an average follow-up of 20 years [37]. Partial meniscectomy is strongly associated with the progression of articular cartilage damage despite anatomical ACL reconstruction [90]. Although arthroscopic partial meniscectomy for complete posterior medial meniscus root tear significantly improved ML scores postoperatively, only 56% of patients had improvement in pain, 67% were satisfied with the outcome, and 35% showed radiographic progression of osteoarthritis at a mean follow-up of 77 months [23]. Partial meniscectomy should be considered cautiously in patients with varus-aligned knees [69]. In a controlled trial involving patients without clinical or radiographic osteoarthritis but with symptoms attributable to a degenerative medial meniscus tear, outcomes after arthroscopic partial meniscectomy were no better than those after a sham procedure [35]. Knee arthroscopic surgery, in most cases consisting of partial meniscectomy or diagnostic arthroscopy, in addition to exercise therapy in middle-aged patients with meniscal symptoms, did not increase the rates of radiographic or symptomatic OA and resulted in similar patient-reported outcomes at the 10-year follow-up compared with exercise therapy alone [28]. Early arthroscopic partial meniscectomy for symptomatic irreparable tears in stable knees without preoperative arthrosis had better improvement in clinical results than delayed intervention [14]. Current level 3 and 4 evidence suggests that arthroscopic repair may result in slower progression of radiological deterioration compared with meniscectomy and nonoperative management for acute meniscus root tears [199]. The findings from determining the Patient Acceptable Symptomatic State allow researchers and clinicians to determine if partial meniscectomy is meaningful to patients and will be helpful for responder analysis in future trials related to knee arthroscopy and the treatment of meniscal pathology [18]. Patients with grade II, III, or IV chondromalacia had a higher rate of unsatisfactory results (33%) compared with patients with less than grade II chondromalacia (9%) following isolated arthroscopic partial meniscectomy [26]. Younger patients had a high percentage of satisfactory results that are maintained at relatively long-term followup of 5 years following isolated arthroscopic partial meniscectomy [26]. Eighty-two percent of patients had satisfactory knee function and activity level was maintained at a minimum followup of 5 years following isolated arthroscopic partial meniscectomy [26].

Treatment

Non-Operative

Physiotherapy is noninferior to arthroscopic partial meniscectomy for knee function over a 24-month period in patients with knee pain and nonobstructive meniscal tears [59]. There is currently no compelling evidence to support arthroscopic partial meniscectomy versus physical therapy [77]. In patients aged 35 to 65 years with knee pain lasting more than 3 months, no obvious traumatic onset, and no knee osteoarthritis, arthroscopic partial meniscectomy was not better than sham surgery for medial meniscal tear [203]. Many medial meniscal tears are correctly treated non-operatively [68].

Operative

Indications: The role of arthroscopic partial meniscectomy remains controversial; while some surgeons believe it provides dramatic pain relief for specific indications, randomized clinical trials generally do not support its efficacy for degenerative meniscal tears, particularly in patients with osteoarthritis [22]. The editors respectfully challenge the statement that partial meniscectomy has no value beyond placebo, asserting that when proper indications are chosen, the surgery works [71]. Arthroscopic partial meniscectomy may be indicated in patients with radial tear if conservative treatment fails [72]. Partial meniscectomy offers pain relief and functional improvement for medial meniscus tear with intact posterior root [34]. Arthroscopic partial meniscectomy for flap tears yielded favorable 12-month outcomes [36]. The use of partial meniscectomy to manage degenerative meniscus tears in knees with mild preexisting arthritis and mechanical symptoms may be beneficial; however, its routine use in the degenerative knee over physical therapy alone is not supported [16]. Partial meniscectomy for a complete medial meniscus posterior root tear provides no benefit in halting arthritic progression compared to non-operative treatment [2, 142, 150, 152]. Partial meniscectomy should be considered cautiously in patients with varus-aligned knees with degenerative medial meniscal posterior root tears [69].

Surgical Approach / Technique: Most tears not amenable to repair can be carefully contoured to preserve viable meniscal tissue [78]. The major advantages of arthroscopic partial meniscectomy over both open partial and total meniscectomy included decreased hospitalization, shorter recovery time, and a reduction in patient care costs [78].

Pain Management: 82% of patients who undergo arthroscopic partial meniscectomy and/or chondroplasty can achieve satisfactory pain control with nonopioid pain management [135]. Intraarticular tramadol plus periarticular bupivacaine combination provides better pain relief and less analgesic requirement following arthroscopic outpatient partial meniscectomy surgery [188]. There were no differences in pain severity and analgesic intake between intra- or extra-articular bupivacaine administration after arthroscopic partial meniscectomy [176]. In patients undergoing arthroscopic meniscal surgery, the chronicity of preoperative opioid intake and degree of knee osteoarthritis were found to have a significant effect on postoperative opioid use [223].

Setting of Care: 0.9% of primary arthroscopies performed under local anaesthesia could not be performed safely due to patient discomfort [200].

Other Considerations: Temporary postoperative treatment with compartment-unloading knee braces or wedge insoles does not improve clinical outcome after partial meniscectomy [217]. Patients with an anxiety or depressive disorder have higher rates of health care utilization, medical complications, opioid prescriptions, and subsequent knee surgery after isolated primary arthroscopic partial meniscectomy [214]. Partial meniscectomy is not considered to be a risk factor for graft failure at short-term follow-up [7]. Good long-term clinical results in terms of stability, subjective outcomes and objective evaluation were reported both for medial CMI implant and partial medial meniscectomy in patients with concomitant ACL reconstruction [80]. In younger populations, partial meniscectomy may provide equal long-term symptom relief, earlier return to play, and lower revision surgery rate compared with meniscal repair [16]. Meniscectomy remains a frequent orthopedic procedure despite the existence of meniscus repair techniques with good clinical outcomes [157].

Long-Term Outcomes and Osteoarthritis Risk: Partial meniscectomy may result in earlier development of osteoarthritis [16]. Post-meniscectomy pain syndrome and post-meniscectomy knee OA are common findings after meniscus resection [65]. Meniscectomy offers a fast return to play with good short-term results, but the long-term risk of osteoarthritis must be weighed when making the appropriate patient selection [15]. In the mid- to long-term follow-up (15–22 years), 27% of patients who had a prior meniscus surgery developed symptomatic radiographic tibiofemoral OA, compared to 10% of non-operated controls, representing a relative risk of 2.6 times for patients with meniscus interventions [58]. The amount of meniscus loss was identified as a risk factor for degenerative changes in the knee joint, suggesting that patients with partial meniscectomy have a lower risk compared to those having subtotal or total meniscectomy [58]. The relative risk of symptomatic OA after subtotal meniscectomy is 2.2, whereas for total meniscectomy is 3.6 compared to partial meniscectomy [58]. Patients treated with primary meniscectomy have over three times higher odds to undergo subsequent knee arthroplasty compared to those treated with meniscal repair in patients older than age 40 [43]. Previous knee surgery, particularly meniscectomy, is associated with full-thickness cartilage loss in the lateral compartment [11]. After meniscectomy, the tibiofemoral contact area decreases by approximately 50%, whereas the contact forces increase 2- to 3-fold [76].

Specific Populations: Early radiographic signs of knee joint degeneration in addition to clinical symptoms of premature arthritis and disability after meniscectomy in a paediatric and adolescent population seem to be even more compelling than in adults [58]. After a mean follow-up of 5.5 years (3–14), only 40% of children with a mean age of 15 years at the time of meniscectomy showed excellent (25%) or good results (15%), and 80% showed signs of radiographic changes [58].

Clinical Results: The results of partial meniscectomy in non-work-related patients were excellent to good, with 96% return to daily activities [56]. In 217 cases with meniscal damage only, 183 (84 per cent) were symptomatically cured by arthroscopic partial meniscectomy and have not reported any further knee symptoms [8]. In 13 patients (6 per cent) with meniscal damage only, arthroscopic partial meniscectomy either failed to give any symptomatic improvement at all or resulted in only short-term relief [8]. Many of the studies of arthroscopic partial meniscectomy reported 80% to 90% satisfactory clinical results with, however, only short-term follow-up (<2 years) [78].

Complications

Surgical Safety and Adverse Events: Both meniscectomy and meniscal repair are safe surgical procedures with low adverse event rates of 0.95% and 1.4%, respectively [195]. Complications following meniscal surgery are associated with medical comorbidities, older age, and longer operative times [195]. Meniscal repair is associated with higher rates of early complications compared with meniscectomy [129], and a greater complication rate can be expected with meniscal repair, especially in patients aged 42 years and younger [179].

Osteoarthritis and Joint Degeneration: Partial meniscectomy increases the risk of developing knee osteoarthritis, particularly in female patients with obesity who undergo large meniscal resection [88]. Simultaneous partial meniscectomy in knees with localized, severe chondral damage caused a higher degree of osteoarthritis rather than decreasing knee function further [6]. Radiographic evidence of abnormal stress transfer to articular cartilage and subchondral bone, evidenced by Fairbank’s changes, was seen after arthroscopic partial meniscectomy [26]. A greater degree of ipsilateral compartment degeneration is seen after partial meniscectomy compared to repair for horizontal cleavage tears [179]. Conversely, meniscal repair is associated with a lower progression to knee osteoarthritis at approximately six years of follow-up compared to partial meniscectomy [24]. Partial medial meniscectomy in stable knees causes only mild joint space narrowing, with a mean of 1.2 mm at a mean 12-year follow-up [9]. Meniscus root repair leads to significantly less arthritis progression compared with nonoperative management and partial meniscectomy [45]. Better outcomes were seen after meniscal repair compared with partial meniscectomy for medial meniscus root tears, with lower rates of progression to knee osteoarthritis [79].

Progression to Arthroplasty: Patients treated with primary meniscectomy have over three times higher odds to undergo subsequent knee arthroplasty compared to those treated with meniscal repair [43]. Patients developing a meniscal tear undergoing arthroscopic partial meniscectomy are at greater risk of knee arthroplasty than the general population, with the risk being three-times greater in the affected knee than in the contralateral knee [239]. When meniscus repair is performed, this is associated with a lower rate of future total knee arthroplasty compared to partial meniscectomy [240]. Meniscus root repair leads to significantly less subsequent knee arthroplasty compared with nonoperative management and partial meniscectomy [45].

Reoperation and Revision Rates: Meniscal repair leads to significantly lower rates of reoperation compared with meniscectomy in a large database study [129]. However, the risk of any knee reoperation after meniscal repair had a four-fold increase compared with partial meniscectomy, and for same meniscus reoperations about 17-fold [95]. Whereas meniscal repairs have a higher reoperation rate than partial meniscectomies, they are associated with better long-term outcomes [83]. The overall secondary partial meniscectomy rate after ramp repair is 10.8% [235]. At a minimum of 2-years postoperative, 5 (19%) of the partial meniscectomy patients had reoperations or failures for horizontal cleavage tears [231]. In a series of 291 consecutive arthroscopic partial meniscectomies, 13 patients (6%) required further arthroscopy due to failure or short-term relief [8]. Revision rates are increased in patients undergoing lateral meniscectomy compared to medial meniscectomy [88].

Functional Outcomes and Patient Satisfaction: In a controlled trial involving patients without clinical or radiographic osteoarthritis but with symptoms attributable to a degenerative medial meniscus tear, outcomes after arthroscopic partial meniscectomy were no better than those after a sham procedure [35]. In young patients with isolated traumatic meniscal tears, early arthroscopic partial meniscectomy was not superior to a strategy of physical therapy with optional delayed arthroscopic partial meniscectomy at 24-month follow-up [27]. A majority of patients receiving arthroscopic partial meniscectomy achieved the Minimal Clinically Important Difference, Substantial Clinical Benefit, and Patient Acceptable Symptomatic State by 6 months [84]. For complete posterior medial meniscus root tears with early osteoarthritis, only 56% of patients had improvement in pain and 67% were satisfied with the outcome of partial meniscectomy at a mean follow-up of 77 months [23]. Thirty-five percent of patients undergoing partial meniscectomy for complete posterior medial meniscus root tears showed radiographic progression of osteoarthritis at a mean follow-up of 77 months [23]. The role of arthroscopic partial meniscectomy remains controversial, as randomized clinical trials generally do not support its efficacy for degenerative meniscal tears, particularly in patients with osteoarthritis [22].

Other Considerations: In a series of 291 consecutive arthroscopic partial meniscectomies, 13 patients (6%) experienced failure to give any symptomatic improvement or only short-term relief [8]. In four cases of arthroscopic partial meniscectomy, the procedure failed to bring about any symptomatic improvement and a second arthroscopy revealed meniscal damage [8].

Recovery

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

Full activity (months): Patients with concomitant meniscal resection are able to reach the same subjective knee function as isolated ACL reconstructions as early as 6 months postoperatively [172]. Athletes who return to sport at approximately 3 months following a partial lateral meniscectomy may employ compensation strategies during landing, evidenced by reduced quadriceps recruitment and functional outcome scores [153].

Complete recovery / outcome plateau (months): The provided evidence does not specify a month range for when pain, strength, and final functional outcomes stabilise.

Rehabilitation protocol: Standard exercise therapy under the supervision of a physiotherapist improved the functional recovery of the knee after partial arthroscopic meniscectomy [138]. An international EU–US consensus established recommendations for rehabilitation of patients after partial meniscectomy and return to sport criteria [33]. An international formal consensus established clear, updated and structured recommendations for both surgeons and physiotherapists treating patients after meniscus surgery [164]. Results suggest worse functional effects when meniscectomy is applied, which implies modification of the rehabilitative methods in a postoperative period [160].

Functional milestones: Patients aged 40 years and younger who underwent partial meniscectomy surgery within 6 months after a meniscal tear were more likely to have a shorter time to return to activity [74].

Other Considerations: Female patients with obesity (BMI ≥27 kg/m²), especially those with medial meniscal tears, tended to have inferior clinical outcomes after partial meniscectomy [74]. The long-term risk of osteoarthritis must be weighed when making the appropriate patient selection for meniscectomy [15]. Among patients who underwent arthroscopic partial medial meniscectomy with an average follow-up of 20 years, those with concurrent focal cartilage defect in the medial compartment had clinically and radiologically worse outcomes than patients without any cartilage defect [37]. Arthroscopic meniscal repair offers significantly improved results for isolated traumatic meniscal tears regarding the long-term follow-up in osteoarthritis prophylaxis and sports activity recovery compared with partial meniscectomy [173]. Meniscectomy for discoid medial meniscus produced promising short-term results but deteriorating long-term results with secondary degeneration of cartilage in the medial compartment [205]. Better outcomes were seen after meniscal repair compared with partial meniscectomy for medial meniscus root tears, with greater improvements in Lysholm scores, lower rates of progression to knee osteoarthritis, and lower reoperation rates [79].

• [L4] Meniscal injury has a negative effect on the biology of the knee within a very short period of time, with degenerative changes of the articular cartilage becoming apparent within a decade. [161] (10.1016/j.csm.2019.08.001)
• [L1] This international formal consensus established clear, updated and structured recommendations for both surgeons and physiotherapists treating patients after meniscus surgery. [164] (10.1002/ksa.12674)
• [L3] Patients with concomitant meniscal resection are able to reach the same subjective knee function as isolated ACL reconstructions as early as 6 months postoperatively. [172] (10.1007/s00167-017-4793-2)
• [L3] Arthroscopic meniscal repair offers significantly improved results for isolated traumatic meniscal tears regarding the long-term follow-up in osteoarthritis prophylaxis and sports activity recovery compared with partial meniscectomy. [173] (10.1177/0363546510364052)
• [L1] There were no differences in pain severity and analgesic intake between intra- or extra-articular bupivacaine administration after arthroscopic partial meniscectomy. [176] (10.1177/23259671221147514)
• [L4] [177] (10.1007/s00167-008-0508-z)
• [L2] However, a greater complication rate can be expected with repair, especially in patients aged 42 years and younger, while a greater degree of ipsilateral compartment degeneration is seen after partial meniscectomy. [179] (10.1016/j.arthro.2024.10.009)
• [L3] Statistically derived formulae can be used to predict the outcome of one knee scoring system when the result of another is known in patients with meniscal tears before and after arthroscopic meniscectomy. [181] (10.1016/j.otsr.2021.102803)
• [L3] In patients aged 40 years and older, patient-reported outcomes at an average of 5 years postoperatively were satisfactory and similar in patients undergoing meniscal repair and meniscectomy, indicating that age alone should not be a contraindication to meniscal repair. [187] (10.1007/s00167-020-06299-5)
• [L2] Intraarticular tramadol plus periarticular bupivacaine combination provides better pain relief and less analgesic requirement following arthroscopic outpatient partial meniscectomy surgery. [188] (10.1007/s00167-006-0221-8)
• [L5] Both meniscectomy and meniscal repair are safe surgical procedures with low adverse event rates (0.95% and 1.4%, respectively), but complications are associated with medical comorbidities, older age, and longer operative times. [195] (10.1016/j.arthro.2023.12.017)
• [L4] The current level 3 and 4 evidence suggests that arthroscopic repair may result in slower progression of radiological deterioration compared with meniscectomy and nonoperative management. [199] (10.1177/03635465211031250)
• [L4] 0.9% of primary arthroscopies performed under local anaesthesia could not be performed safely due to patient discomfort. [200] (10.1007/s001670050171)
• [L3] A supplementary MRI will increase diagnostic accuracy when fewer than three clinical findings are present in a symptomatic meniscal repair patient. [201] (10.1007/s00167-019-05523-1)
• [L1] [203] (10.2106/jbjs.9616.ebo521)
• [L4] Meniscectomy for discoid medial meniscus produced promising short-term results but deteriorating long-term results with secondary degeneration of cartilage in the medial compartment. [205] (10.1007/s00167-012-1979-5)
• [L4] Articular cartilage and meniscus exhibit molecular events associated with OA at the time of partial meniscectomy despite no gross evidence of degeneration in the knee. [206] (10.1177/2325967115s00065)
• [L3] MRI is not always useful in predicting reparability of symptomatic isolated lateral semilunar meniscus tears, and most of the symptomatic cases with normal MRI were reparable. [207] (10.1007/s00167-002-0280-4)
• [L5] [209] (10.1177/0363546513498503)
• [L5] [210] (10.1016/j.csm.2012.08.017)
• [L2] The diagnostic validity of magnetic resonance imaging is similar for meniscal tears in acute knee trauma and in knee symptoms lasting over 6 months in young adults. [212] (10.1177/0363546508329543)
• [L3] Patients with an anxiety or depressive disorder have higher rates of health care utilization, medical complications, opioid prescriptions, and subsequent knee surgery after isolated primary arthroscopic partial meniscectomy. [214] (10.1016/j.arthro.2025.01.067)
• [L1] [217] (10.1007/s00167-018-5106-0)
• [L4] Arthroscopic repair of isolated medial degenerative meniscus tears in patients over 45 years resulted in good to excellent clinical outcomes with low clinical failure rates, despite unhealed menisci being observed on MRI in 41% of patients. [218] (10.1007/s00167-022-07133-w)
• [L3] In patients undergoing arthroscopic meniscal surgery, the chronicity of preoperative opioid intake and degree of knee osteoarthritis were found to have a significant effect on postoperative opioid use. [223] (10.1016/j.arthro.2018.10.122)
• [L3] [226] (10.1002/ksa.70202)
• [L3] At a minimum of 2-years postoperative, 4 (15%) of the circumferential repair patients had reoperations or failures, while 5 (19%) of the partial meniscectomy patients had reoperations or failures. [231] (10.1177/2325967126s00376)
• [L3] The overall secondary partial meniscectomy rate after ramp repair is 10.8%, and anterolateral ligament reconstruction appears to confer a protective effect on the ramp repair. [235] (10.1177/0363546518800717)
• [L2] Patients developing a meniscal tear undergoing APM are at greater risk of knee arthroplasty than the general population, with the risk being three-times greater in the affected knee than in the contralateral knee. [239] (10.1302/0301-620x.101b9.bjj-2019-0335.r1)
• [L3] When meniscus repair is performed, this is associated with lower rate of future total knee arthroplasty. [240] (10.1016/j.arthro.2025.05.006)
