Open and arthroscopic lateral ligament repair for treatment of chronic ankle instability: A systematic review

Background

Chronic ankle instability is defined by an instability lasting more than 6 months, in those cases where a comprehensive conservative treatment fails a surgical stabilization is required. Several surgical techniques have been proposed for the management of the chronic lateral instability of the ankle and even after 50 years, the Broström–Gould technique is still considered the gold standard for the treatment of this pathology. Recently, many authors have developed completely arthroscopic lateral ligament repair and the use of these procedures is rapidly increasing. The aim of this review is to provide an updated overview of open and new arthroscopic lateral ligament repair techniques in order to summarize and compare the effectiveness of these strategies.

经皮踝外侧韧带复合体重建治疗慢性踝外侧不稳

[目的]探讨经皮功能重建踝关节外侧韧带复合体治疗慢性踝关节不稳的临床疗效。[方法]2014年1月~2018年2月,符合纳入标准的47例慢性踝关节不稳患者随机分为两组,其中,切开组23例采用常规切开术式重建距腓前韧带(ATFL)和跟腓韧带(CFL),经皮组24例采用超声定位,经皮建立骨隧道重建ATFL和CFL。比较两组间手术时间、围术期并发症、踝背伸-跖屈活动度(ROM)、AOFAS评分、VAS评分,应力位影像测量距骨前移度和倾斜度。[结果]术中切开组2例出现腓浅神经损伤。经皮组手术时间、切口总长度显著小于切开组,差异有统计学意义(P<0.001)。切开组术后4例切口边缘处坏死,而经皮组1例切口渗液。两组患者随访26~30个月,平均(27.39±2.51)个月。术后6个月时,经皮组ROM显著大于切开组(P<0.05)。随时间推移两组患者AOFAS评分均显著增加,而VAS评分显著减少(P<0.001),但是两组相同时间点AOFAS评分和VAS评分的差异均无统计学意义(P>0.05)。应力位X线测量方面,术后两组患者距骨前移距度和距骨倾斜角均较术前显著减少(P<0.001)。但是两组相同时间点在距骨前移距度和距骨倾斜角的差异均无统计学意义(P>0.05)。[结论]经皮踝关节外侧韧带复合体重建治疗慢性踝关节不稳的效果与常规开放手术相当,但具有手术时间短、创伤小、并发症少的优点。

Double-bundle reconstruction of the anterior talofibular ligament by partial peroneal brevis tendon

BackgroundAnatomic anterior talofibular ligament (ATFL) reconstruction with autologous single-bundle tendon has been widely used in the treatment of ATFL injury. However, there are few clinical reports of using the peroneus brevis tendon (PBT) for double-bundle ATFL reconstruction. The aim of this study was to investigate the clinical effect of double-bundle ATFL reconstruction with PBT.MethodsThis was a retrospective review of all patients diagnosed with ATFL injury presenting from August 2019 to December 2021. Fifty-three patients were selected after screening based on the inclusion and exclusion criteria. The following data were compared before and after surgery: Visual Analogue Scale (VAS) score, American Orthopedic Foot and Ankle Society (AOFAS) score, Karlsson Ankle Functional Score (KAFS), the pain interference (PI) and physical function (PF) scores of the Patient-Reported Outcomes Measurement Information System (PROMIS), the diameter and width of PBT in ultrasound and muscle strength.ResultsAll functional scores (VAS, PI/PF, AO-FAS, KAFS) and muscle strength were significantly improved at the last follow-up (P < 0.05). The diameter and width of the PBT on ultrasound postoperation were smaller than those preoperatively.ConclusionDouble-bundle ATFL reconstruction with the partial PBT technique is a feasible, anatomic reconstruction technique for chronic lateral instability of the ankle, which meets the anatomical characteristics of the double bundle of the ligament, and the absence of partial PBT does not affect the peroneal muscle strength.Level of evidenceLevel IV, retrospective case series.     

MRI appearance of the lateral fibulotalocalcaneal ligament complex injury in the patients with chronic lateral ankle instability

BackgroundThe anterior talofibular ligament (ATFL) comprises the superior and inferior fascicles. The inferior fascicle is connected to the calcaneofibular ligament, and forms “lateral fibulotalocalcaneal ligament (LFTCL) complex”. This study aimed to evaluate the feasibility of diagnosing LFTCL complex injuries in patients with chronic lateral ankle instability (CLAI).MethodsForty-eight ankles (35 with CLAI and 13 without CLAI) underwent arthroscopic surgery, and preoperative magnetic resonance imaging (MRI) was conducted with 0.8 mm- thick axial and oblique slices. The diagnostic accuracy of injuries to the superior fascicle and LFTCL complex was evaluated by two observers.ResultsThe sensitivity and specificity of the LFTCL complex injury were 94.7% and 92.3% for observer 1 and 84.2% and 84.6% for observer 2, respectively.ConclusionsMRI with 0.8 mm slices could detect LFTCL complex injury in patients with CLAI. Diagnosing the LFTCL complex injury on MRI will improve outcomes of an arthroscopic isolated ATFL repair.

Lateral ligament injury of the ankle and associated articular cartilage degeneration in the talocrural joint: anatomic study using elderly cadavers

We investigated degenerative changes (DCs) of the articular cartilage using 33 cadaveric talocrural joints with anterior talofibular ligament injuries. The control group (93 normal ankles) were age- and sex-matched with the injury group. The injured ligament carried unusual wavy collagen bundles with hyalinization (or elongation) or rupture with scar. In both groups, we found talar-side dominance of DCs, multifocus occurrence, and a high incidence of mirror-image DCs in the medial parts of the joint. However, the mirror-image lesion was multiple or large (or both) in the injury group in contrast to its restricted nature in the control. Thus, the averaged numbers of affected areas or sectors in the injury group were almost twice as large as in the controls. A significantly high incidence of DCs, especially of the mirror-image lesion, was found in the lateral malleolar facet in the injury group. Although initial DC lesions might be at a medial site in the joint, as hypothesized in the control group, the lateral ligament injury seemed to increase the dominance of DCs on the lateral site. Consequently, early evaluation and treatment for lateral ligament insufficiency is more necessary in elderly patients than in younger patients to avoid widespread development of osteoarthritis.
