Lateral ligament reconstruction

Overview¶
Reconstruction of the unstable lateral ligament complex is a relatively stable treatment for chronic ankle instability, yielding a high rate of success [1, 4]. The primary surgical options are anatomic ligament repair with reinforcement and anatomic ligament reconstruction [2]. These procedures are indicated for patients with severe chronic lateral ankle instability, where allograft reconstruction serves as a valid treatment option that leads to satisfying outcomes and reduced joint morbidity [3]. Anatomic stabilization techniques provide superior functional results compared to non-anatomic methods [37]. While anatomic reconstruction often yields the best results, it may be more invasive than anatomic repair [37]. Ligament reconstruction may offer superior results specifically when there is a high preoperative ATFL-SNR [10].
Operative techniques include open and arthroscopic approaches, as well as direct repair or reconstruction using autograft or allograft [31]. Arthroscopic lateral ankle ligament repair yields favorable short-term clinical outcomes [15, 22]. When feasible, arthroscopic repair produces similarly favorable outcomes compared to open lateral ankle repair [33]. Open and arthroscopic ligament repair produced excellent comparable clinical outcomes at 5 years follow-up [23]. Endoscopic ligament reconstruction is a safe procedure that produces good clinical results with minimal complications [20]. It is likely that arthroscopic rather than open lateral ankle ligament repair will become the standard of care in the future [22]. However, arthroscopic techniques require further evaluation to better determine indications and long-term outcomes [32].
The current recommendation is for open anatomic repair or reconstruction [29]. A simple non-augmented repair is acceptable with a high success rate for selected individuals with good indications [26]. If disruption of the lateral ligaments is noted at operation, repair is indicated as it markedly increases the chances for a stable ankle [6]. Lateral ligament augmentation demonstrates superior mechanical stability and functional outcomes compared to the modified Broström repair in treating chronic lateral ankle instability [47]. When compared with lateral ankle repair, anatomic allograft reconstruction produced similarly favorable outcomes, including high patient satisfaction, high function and activity levels, and no revision surgeries in either cohort [73]. The reconstructive armamentarium is detailed along with outcomes and potential complications to guide surgeons in the most appropriate treatment for their patients [46].
Anatomy & Pathophysiology¶
Ligament Anatomy and Injury Mechanisms¶
Inversion of the foot is the most common mechanism of injury to the ankle ligaments [70]. In this inversion mechanism, the anterior talofibular ligament is the first or only ligament to sustain injury [70]. A total rupture of the lateral ankle ligaments involves the calcaneofibular ligament and the posterior talofibular ligaments [70]. Conversely, an eversion injury causes damage to the deltoid ligaments [70], while hyperdorsiflexion trauma might cause an injury to the syndesmotic ligaments [70].
The anterior talofibular ligament consists of distinct fascicles with specific anatomical relationships. The inferior fascicle is connected to the calcaneofibular ligament [156]. The superior fascicle is an intra-articular structure [156]. The intra-articular position of an injured anterior talofibular ligament superior fascicle is thought to impair healing [156].
Pathophysiology of Chronic Instability¶
Chronic ankle pain often finds its cause in laxity of one of the ankle ligaments [70]. The dynamic congruency of the joint, which is influenced by ligamentous integrity, remains the main anatomical component in mechanical ankle instability [84]. Three-dimensional talar shape is not a factor in chronic mechanical ankle instability [84].
Cellular and sensorimotor changes characterize chronic instability. Apoptosis occurs in the anterior talofibular ligament of patients with chronic lateral ankle instability [184]. The number of mechanoreceptors is negatively correlated with ankle sensorimotor dysfunction in chronic ankle joint instability [106]. Patients with chronic ankle instability have longer electromechanical delay times in neutral but not when the ankle is placed in inversion [104].
Kinematic alterations extend beyond the ankle joint. Alterations of kinematics in athletes with chronic ankle instability are found not only at the ankle but also at hip joints during the side-cutting movement [89]. Individuals with chronic ankle instability display different ankle joint coupling patterns and coordination variability during a walking gait cycle compared to copers and controls [111]. Athletes with chronic ankle instability demonstrate dynamic stability deficits, and the direction of the jump can affect dynamic postural stability in the sagittal and frontal planes [128].
Landing strategies and balance are compromised. Single-leg drop landing movement strategies in participants with chronic ankle instability are altered compared to lateral ankle sprain copers [130]. These alterations in landing movement strategies may be responsible for the increased risk of injury experienced by individuals with chronic ankle instability during landing manoeuvres [130]. Dynamic balance deficits in individuals with chronic ankle instability are attested to reduced sagittal plane motions at the hip, knee and ankle joints, and reduced capacity of the stance limb to avail of its supporting base [96].
Osseous morphology may contribute to susceptibility. Most studies found distinct characteristics of the incisura fibularis morphology associated with ligamentous ankle lesions, potentially due to lower osseous resistance against tibiofibular displacement [107]. Further investigations are required to clarify the characteristic foot and ankle malalignment in chronic ankle instability [94].
Biomechanics and Stability¶
Stability of the loaded ankle is primarily due to the deltoid ligament, which exerts a restraining influence on external rotation of the talus [125]. Sectioning of the deltoid ligament resulted in a 43% increase in tibiotalar contact area while peak pressures increased 30% [135]. Sectioning of the deltoid ligament alone results in valgus tilt of the talus and therefore chronic instability, which may lead to tibiotalar arthrosis [135].
The accessory anteroinferior tibiofibular ligament is a normal anatomical finding that could lead to anterolateral impingement in cases with coexistent ankle instability [127]. The peroneal tendons play a role in the passive stabilisation of the ankle joint [98]. The MLPP system is capable of measuring anterior talofibular ligament strain patterns to determine the relationship between limb position and ligament strain [115].
Diagnostic measurements vary with position and modality. Plantar flexion of the ankle produces changes in radiographic measurements of the medial clear space [91]. Ultrasound can reliably measure the medial clear space of the ankle while doing dynamic stress manoeuvres [101]. No significant difference was detected between the contralateral healthy ankles of subjects with ipsilateral mechanical lateral ankle laxity and those of bilateral healthy controls [137].
Surgical Biomechanics and Reconstruction Outcomes¶
The anterior talofibular ligament–posterior talofibular ligament angle decreases after ankle lateral stabilization surgery [28]. It is possible to restore ankle stability with anatomical reconstruction without impairing the range of movement in the ankle joint complex [88]. Approximate ankle kinematic patterns and sufficient laxity, even with an initial tension of 10 N, could be obtained immediately after anterior talofibular ligament reconstruction [83]. Ankle kinematic patterns and laxity after calcaneofibular ligament reconstruction tended to become more abnormal as the initial graft tension increased at the time of surgery [90].
Both arthroscopic and open repair techniques appear biomechanically equivalent in their ability to restore ankle stability [87, 97]. The Brostrom-Gould procedure re-establishes ankle stability in patients with chronic ankle instability, with no significant differences in kinematic patterns or range of motion between reconstructed and contralateral uninjured ankles [117]. Lateral ankle ligament reconstruction with an allograft using 1 fibular tunnel demonstrated similar biomechanical stability to the 2-tunnel approach [118]. The interference screw provides superior biomechanical properties for free tendon reconstruction of the anterior talofibular ligament [122].
For multiligamentous and syndesmotic injuries, combined approaches yield specific outcomes. A combined repair or a combination of repair and bracing closely restored rotational stiffness and ankle stability in case of a multiligamentous ankle injury in a cadaveric model [129]. A novel anatomical reconstruction technique using autogenous peroneus brevis tendon restores syndesmotic biomechanics comparable to the intact state, outperforming 3.5 mm tricortical screw fixation in restoring physiologic stability [133]. Tibiocalcaneal augmentation of deltoid ligament repair has a strong stabilizing effect on the ankle joint [110]. Anatomic suture-button fixation achieved the closest biomechanical parameters to those of the intact ankle model for tibiofibular syndesmosis injuries [95]. The operative ankle exhibited greater syndesmosis length and altered kinematics compared to the healthy side during all tested activities following syndesmosis repair [85].
Classification¶
Anatomical Integrity: A total rupture of the lateral ligaments involves the calcaneofibular ligament and the posterior talofibular ligaments [70]. The anterior talofibular ligament is the most frequently ruptured and most important component of the lateral ligaments of the ankle [151]. Anatomically, the superior fascicle of the anterior talofibular ligament is distinct from the inferior anterior talofibular ligament fascicle [150]. The inferior anterior talofibular ligament fascicle shares features with the calcaneofibular ligament to form the lateral fibulotalocalcaneal ligament complex [150].
Clinical Grading: Clinical suspicion of lateral ligament injury is scored on a four-grade scale ranging from Grade 0 (intact ligament) to Grade 3 (complete discontinuity with loss of integrity) [48]. Clinical suspicion of lateral ligament injury is considered positive when scored as Grade 3 [48].
Other Considerations: Grading of the three major ligamentous complexes and individual ankle ligaments according to the Schneck grading system resulted in limited diagnostic reliability on 3 T MRI [102].
Clinical Presentation¶
Chronic ankle instability is defined by ongoing symptoms persisting for at least 6 months, characterized by recurrent sprains, pain, and impairments with perceived instability during sportive activity [92]. A detailed history of the patient's complaints is essential to differentiate between instability resulting from recurrent ligament injury and functional instability not related to increased ligament laxity [60]. Surgical treatment for chronic lateral ankle instability is recommended when patients exhibit symptoms after 3 to 6 months of nonsurgical treatment and physical examination reveals tenderness [86].
Physical examination must include an assessment for generalised ligamentous laxity and of overall lower extremity alignment, particularly hindfoot varus malalignment, which may result in a high likelihood of failure of surgical repair or reconstruction if not addressed [60]. The range of motion (passive and active) of the ankle and subtalar joints is noted during clinical assessment, and gastrocnemius tightness is assessed [60].
Stability testing confirms unilateral mechanical ankle instability using the anterior talar drawer and talar tilt test [92]. The anterior drawer test and hindfoot inversion tests are specifically used to assess for lateral ligament laxity [60]. Ultrasound has manifested high diagnostic accuracy in diagnosing chronic lateral ankle ligament injury [113]. Clinical suspicion of lateral ligament injury is scored on a four-grade scale, where Grade 0 indicates an intact ligament and Grade 3 indicates complete discontinuity with loss of integrity [48].
The presence of intra-articular pathology is recommended to be evaluated by arthroscopy at the time of surgery unless excluded by MRI scan and there is no history of pain [63]. When treating chronic lateral ankle instability, surgeons should consider ligament quality, specifically the anterior talofibular ligament remnant quality, for achieving a stable ankle [66]. Operative procedures that only focus on part of the pathology should be approached with caution until assessment of a patient with ankle instability defines all deficiencies [58]. Diagnostics and treatment for lateral ligament instability should consider the deltoid ligament complex, especially the transverse calcaneonavicular ligament [100].
Investigations¶
MRI: Preoperative MRI serves as a reliable and valid decision-making tool for selecting the surgical stabilization technique in patients with chronic lateral ankle instability [158]. The modality plays an increasingly important role in diagnosing a wide range of foot and ankle abnormalities and planning their surgical treatment [165]. To improve diagnostic accuracy for anterior talofibular ligament injury, the oblique axial-coronal plane can be added to the standard MRI scanning protocol [166]. Isolated injury to the superior fascicle identified on MRI may be useful when diagnosing patients presenting with symptoms of subtle instability without overt ankle laxity on clinical examination [174]. A transformer-based multilabel deep learning model was able to detect lateral and medial collateral ligament injuries based on MRI and outperformed CNN-based models [162].
Point-of-care ultrasound: Point-of-care ankle ultrasound is as precise as MRI for detecting major ankle ligament and Achilles tendon injuries [176].
CT: CT and MRI are excellent imaging modalities that can help the timely diagnosis and appropriate treatment for combined impingement with circumferential lesions [172]. Dixon et al. described an excentric lesion, a symptomatic anterolateral exostosis at the insertion of the anterior talofibular ligament, found by a CT scan in patients with chronic ankle pain after an inversion injury [57]. Anatomic lateral ligament reconstruction using allograft led to accurate tunnel positioning as confirmed by 3D-CT [16].
Plain radiography: With mechanical instability, stress radiographs show 8 to 10 degrees of increased tilt of the talus in the ankle mortise compared with the normal ankle [57]. However, stress radiography did not distinguish between intact and single-ligament disruption and was unreliable in distinguishing between sequential transection models [72]. Radiographic measurements demonstrated excellent agreement among reviewers and across trials, suggesting clinical reproducibility and surgical utility of the defined parameters [175]. Physical examination and oblique radiographs were suggestive of the excentric lesion described by Dixon et al. in most cases [57].
Radiographic Findings: The ATFL–PTFL angle decreases after ankle lateral stabilization surgery [28]. Radiologic residual laxity showed greater varus with isolated direct repair [18]. There was a positive correlation between varus laxity pre-operatively and at follow-up [18]. Patients with greater osteoarthritis showed significantly greater radiologic varus laxity at follow-up [18]. Post-operative evolution of radiologic lesions showed a decrease in Grade 0 (normal) tibiotalar joint lines from 88% pre-operatively to 77% post-operatively [18]. Post-operative evolution of radiologic lesions showed an increase in Grade 1 (osteophytes without impingement) tibiotalar joint lines from 9% pre-operatively to 18% post-operatively [18]. Post-operative evolution of radiologic lesions showed an increase in Grade 2 (impingement with or without osteophytes) tibiotalar joint lines from 3% pre-operatively to 4% post-operatively [18]. Post-operative evolution of radiologic lesions showed an increase in Grade 3 (complete impingement) tibiotalar joint lines from 0% pre-operatively to 1% post-operatively [18].
Associated Pathology: About 20% of athletes referred for MRI after suffering an acute ankle sprain had evidence of a syndesmotic injury regardless of lateral ligament involvement [152]. More than half of athletes referred for MRI after suffering an acute ankle sprain had evidence of any lateral ligament injury without syndesmotic involvement [152].
Treatment¶
Non-Operative¶
Nonsurgical measures, including functional rehabilitation, are the management methods of choice for acute injuries, with surgical intervention reserved for high-demand athletes [67]. Successful treatment of grade II and III acute lateral ankle ligament injuries can be achieved with individualized aggressive, non-operative measures, though acute repair may give better results in professional athletes [27]. The only satisfactory non-operative treatment for injuries to the fibular collateral ligaments of the ankle is immobilization in plaster for at least six weeks [147].
Operative¶
Indications: Reconstruction of the unstable lateral ligament complex using various operative techniques has a high rate of success [1]. A treatment algorithm for chronic ankle instability is based on expert opinion (level V) rather than on clinical evidence, as there is a lack of high-level evidence studies to determine a treatment protocol [36]. It is important to obtain a detailed history of the patient's complaints to help differentiate between instability due to recurrent ligament injury and functional instability, not related to increased ligament laxity [60]. Physical examination must include an assessment for generalised ligamentous laxity and of overall lower extremity alignment (in particular hindfoot varus malalignment) which, if not addressed at the time of surgery, may result in a high likelihood of failure of surgical repair or reconstruction [60]. The range of motion (passive and active) of the ankle and subtalar joints is also noted and gastrocnemius tightness is assessed [60].
Surgical Approach / Technique: The Broström procedure is the gold standard when anatomic reconstruction of the lateral ankle ligaments is attempted [161]. The goal of anatomic reconstruction is to restore the physiologic anatomy by suturing the ligament itself [161]. Exposure of the lateral ankle ligaments can be achieved through a curved incision from the fibula directed anteriorly or posteriorly [161]. The incision directed posteriorly allows a good exposure of the lateral ligaments but has the disadvantage of not being extendable distally [161]. Many surgeons prefer the curved incision directed anteriorly toward the base of the fourth metatarsal [161]. If preoperative examination of the peroneal tendons resulted in unclear diagnostic findings, it is recommended that the tendons be exposed through the same access to possibly identify and repair existing lesions [161]. Painful accessory ossicles in the area of the lateral ligaments are removed [161]. Screw fixation of the fragments to the distal fibula should be considered for very large accessory ossicles [161]. After reconstruction of the ligament, the ATFL and/or the CFL are reattached to the distal fibula using suture anchors or transosseous sutures [161]. The reconstruction can be reinforced using the extensor retinaculum if required [161]. Restoring the CFL plays a relevant role in lateral ligament repair, however sufficient time for ligament healing should be allowed before inversion stresses are applied [13]. The modified Brostrom procedure with a semi-single ligament reconstruction can provide as much initial stability as the two ligaments reconstruction procedure [42]. Over a 5-year follow-up period, primary MBP produced better pain relief and functional recovery than revision to lateral ankle ligament reconstruction (LALR), despite a higher frequency of intra-articular lesions [25]. The arthroscopic Brostrom procedure is a viable alternative to the open procedure, allowing the surgeon to address both lateral ligament instability and associated intra-articular pathologies without extensive dissection [99]. The novel technique of arthroscopic lateral ligament repair using a knotless suture anchor demonstrated significant clinical improvement and good results at final follow-up [50]. Arthroscopic all-inside ATFL repair with suture augmentation gives excellent results in case of poor ligament tissue remnant quality [187]. The strength of fixation with suture anchors in anatomic reconstruction of the ankle lateral ligaments was equivalent to transosseous tunnel fixation as determined with biomechanical testing [188].
Implant Selection: Anatomic lateral ligament reconstruction using allograft led to excellent clinical outcomes and accurate tunnel positioning as confirmed by 3D-CT [16]. Lateral ligament reconstruction using the AHPLT may be a good surgical option for the treatment of chronic ankle instability [24]. All-arthroscopic technique for anatomic reconstruction for chronic lateral ankle instability leads to good clinical results [54]. The anatomic reconstruction of the ankle lateral ligament complex to treat chronic ankle instability using the arthroscopy combined with the fluoroscopic technique could improve the clinical functions, satisfaction, and reduced pain of patients [61]. This hybrid anatomic lateral ligament reconstruction technique using a peroneus longus autograft to substitute the native ATFL provides an alternative to anatomic reconstruction when direct repair is not possible [105]. The use of the plantaris tendon permits an anatomical reconstruction of the lateral ligaments while avoiding sacrifice of the dynamic effect of the peroneus brevis muscle [40]. Reinforcement of the lateral ligaments using tendon grafts is done in the absence of sufficient local tissue (or by poor quality/quantity of local tissue) or by revision surgery [161]. Symptomatic chronic lateral ankle instability could be successfully managed with this easy and effective surgical reconstruction method [51]. The current reconstruction method led to a satisfactory clinical and functional midterm outcome shown by a numeric scale [79]. Carbon fibre reinforcement for chronic lateral ankle instability has the advantage of preservation of inversion, maintenance of peroneal function and simplicity of insertion; in addition the implant does not stretch so the result will not deteriorate with time [78]. Use of the LARS is a viable option in patients for whom the MBG procedure is relatively contraindicated [148]. Surgical resection of the DF-AITFL and ligament reconstruction, when necessary, resulted in significant symptom improvement [55].
Revision: Revision lateral ankle ligament reconstruction (LALR) improves symptoms but outcomes reflect the revision context rather than indicating the procedure is inferior [21].
Other Considerations: Postural control was improved by reconstructing the lateral ligaments [45]. MRI assessment of tendon graft after lateral ankle ligament reconstruction suggests an evolution in graft properties and supports the possibility of creating a viable ligament [44]. Although only fair-quality evidence exists in support of open operative treatment of chronic ankle instability, this systematic review helps reassure clinicians of their current practices [74]. The 80 different surgical interventions and variants found in the literature to treat chronic lateral ankle instability are a sign of the lack of consensus for technical management [12]. Short and intermediate term results for surgical interventions for chronic lateral ankle instability are good or very good in between 80 and 95% of cases [12]. There are very few long-term results evaluating stability and its articular effects in the literature [12]. Three main types of surgical procedures can be identified: tightening of the ligament and capsular tissue, tightening associated with reconstruction and tendon grafts using all or part of the tendon (mainly the peroneus brevis) [12]. The immediate danger of ligamentoplasty procedures are both cutaneous, to avoid extensive subcutaneous detachment (which is why it is important to conserve the inframalleolar fat pad) and neurological because of possible injury to the superficial terminal branches of the sural nerve and the superficial fibular nerve [12]. The anatomical repairs are still the best methods of treatment in symptomatic chronic instability and with the high incidence of intra-articular pathology it is recommended that an arthroscopy is performed at the time of surgery unless intra-articular pathology has been excluded by MRI scan and there is no history of pain [63]. An excellent or good result was achieved in 132 ankles, all of which had improved mechanical stability as measured radiographically [8]. ALALR can produce favorable clinical outcomes in the short term, and it is likely that arthroscopic rather than open lateral ankle ligament repair will become the standard of care in the future [22].
Complications¶
Nerve Injury: The immediate danger of lateral ligamentoplasty procedures includes neurological injury to the superficial terminal branches of the sural nerve and the superficial fibular nerve [12]. The intermediate dorsal cutaneous branch of the superficial peroneal nerve crosses the inferior extensor retinaculum and is the primary structure at risk during arthroscopic repair [171]. In a study of arthroscopic all-inside anterior talofibular ligament repair, 2 patients in the inferior extensor retinaculum reinforcement group experienced superficial peroneal nerve injuries, with symptoms subsiding by 3 months [163]. One patient in each group of an arthroscopic all-inside anterior talofibular ligament repair study presented with neuralgia of the superficial peroneal nerve, which improved over time without treatment [171]. In a cohort of 20 patients undergoing anatomic reconstruction with a semitendinosus allograft, one patient experienced superficial peroneal neurapraxia that resolved and a sural nerve injury that did not recover [181]. In the same cohort of 20 patients undergoing anatomic reconstruction with a semitendinosus allograft, a second patient experienced sural neurapraxia that resolved [181]. In a study of arthroscopic allograft reconstruction for chronic lateral ankle instability, 9.1% of patients experienced minor neurologic complications [80]. In a study of anatomic repair for anterior talofibular ligament injury at the talar side, no patient had superficial peroneal nerve injury [169].
Wound and Infection Complications: The immediate danger of lateral ligamentoplasty procedures includes cutaneous complications, necessitating the avoidance of extensive subcutaneous detachment and conservation of the inframalleolar fat pad [12]. In a cohort of 20 patients undergoing anatomic reconstruction with a semitendinosus allograft, one patient developed a local wound infection with skin slough, which resolved with oral antibiotics and local wound care [181]. One patient in the no-inferior extensor retinaculum reinforcement group of an arthroscopic repair study presented with an abscess requiring local incision and drainage [171]. The minimally invasive nature of percutaneous calcaneal osteotomy combined with arthroscopic lateral ankle ligament reconstruction presents a lower infection risk [199].
Hardware and Suture Complications: In a study of arthroscopic all-inside anterior talofibular ligament repair, one patient in the inferior extensor retinaculum reinforcement group had suture knot irritation around the acAL portal, which improved after knot excision under local anesthesia [163]. Two patients in the inferior extensor retinaculum reinforcement group of an arthroscopic all-inside anterior talofibular ligament repair study had knot irritation causing mild discomfort [171]. In a study of anatomic repair for anterior talofibular ligament injury at the talar side, no patient had knot reaction [169]. Complications of arthroscopic lateral ankle repair include pain or discomfort arising from a prominent anchor or suture knot [163].
Recurrence and Instability: In a study of arthroscopic all-inside anterior talofibular ligament repair, 8.1% of patients in the repair group and 6.7% of patients in the augmentation group had anterior talofibular ligament retear on MRI [163]. All patients who had anterior talofibular ligament retear on MRI in the arthroscopic repair study had recurrent chronic ankle instability with functional discomfort and anterior displacement greater than 3 mm compared with the other ankle [163]. In a study of anatomic repair for anterior talofibular ligament injury at the talar side, 6 patients (15.4%) suffered recurrent sprain after return to sport [169]. The presence of one or more risk factors should influence the surgical strategy to mitigate the risk of treatment failure after lateral ankle ligament repair [198]. Concomitant ankle arthroscopy procedures performed with ankle ligament procedures did not decrease the rate of reoperation [196].
Functional Limitations and Pain: Reduced tibiotalar dorsiflexion significantly reduced the number of good and very good results in a long-term review of peroneus brevis ligamentoplasty, and was the only apparent cause of poor results [123]. In a study of anatomic repair for anterior talofibular ligament injury at the talar side, ROM deficiency was found in eight patients (25%) with a feeling of ankle stiffness [169]. Of the eight patients with ROM deficiency in the talar-side ATFL repair study, five presented with 5–10 degrees of dorsiflexion limitation and three presented with 5–10 degrees of inversion limitation [169]. In a long-term prospective study of chronic lateral ankle instability surgical repairs, Karlsson scores were significantly poorer with Castaing peroneus brevis plasty, principally due to the "pain" and "residual instability" components [18]. In the same long-term prospective study, radiologic residual laxity showed greater varus with isolated direct repair [18]. In the same long-term prospective study, patients with greater osteoarthritis showed significantly greater radiologic varus laxity at follow-up [18].
General Complication Rates: The wide variations in the reported complication rates for arthroscopic lateral ankle repair range from 0% to 29% [171]. The complications of arthroscopic lateral ankle repair include nerve pain, knot irritation, delayed wound-healing, and deep vein thrombosis [171]. In a study of arthroscopic all-inside anterior talofibular ligament repair with and without inferior extensor retinacular reinforcement, there were no other complications in the repair group besides those noted [163]. In a study of anatomic repair for anterior talofibular ligament injury at the talar side, no patient had infection or revision surgery [169]. In a study of immediate weightbearing after augmented modified Broström reconstruction, most patients achieved excellent functional outcomes by 6 weeks with minimal complications [71]. In a study of surgical fibular tendon stabilisation by isolated re-tensioning of the superior fibular retinaculum, the technique is associated with a very low complication rate [81].
Recovery¶
Light activity (weeks): Most patients achieve excellent functional outcomes by 6 weeks following an accelerated rehabilitation protocol after augmented modified Broström reconstruction, with minimal complications and high satisfaction [71]. Immediate weightbearing is a safe and practical postoperative rehabilitation method that can be applied after arthroscopic lateral ankle ligament repair [138].
Full activity (months): Patients with chronic lateral ankle instability who underwent arthroscopic allograft reconstruction successfully returned to preinjury occupations within 5 months and sports within 9 months [80]. In a cohort of patients with chronic lateral ligament instability treated with plication and extensor digitorum brevis transfer, all 30 patients returned to normal sporting activity, including National Championships and Olympic representation [59]. All patients were able to return to their normal occupations after operation for lateral ligament reconstruction [170]. Good patient-reported outcomes as well as excellent return to sport and return to work rates can be achieved in high-risk patients undergoing ankle ligament reconstruction with a tendon autograft for chronic lateral ankle instability [68].
Rehabilitation protocol: An accelerated rehabilitation pathway after modified Broström repair is supported by findings indicating safety and efficacy in both athletic and general populations [144].
Functional milestones: The ALR-RSI is a valid, reproducible scale with which to identify patients who are ready to resume the same sport after ankle ligament reconstruction [146].
Other Considerations: Distal rupture near the talar or calcaneal end of the lateral ankle ligament was associated with delayed return-to-sport and inferior performance in resuming pre-injury sports level [189]. There is fair evidence showing a worse clinical outcome score in combined ligament ruptures, as well as a decreased return to full sports activities [190]. A systematic review identifies a clear deficiency in the literature pertaining to consistent, meaningful postoperative return to sport timeline following lateral ankle ligament repair [49]. In a small group of patients undergoing lateral ankle stabilization after distal fibular resection, patients were able to return to normal daily activities without instability or progression to tibiotalar arthrosis at short term [145].
