Research Progress in Arthroscopic Treatment of Chronic Lateral Ankle Instability (CLAI)
Abstract
Methods: Literature from the past 20 years on arthroscopic treatment of CLAI was reviewed. The advantages and disadvantages of vari
ous surgical techniques were summarized, and their efficacy for CLAI was evaluated. Results:Arthroscopic treatments for CLAI are mainly
divided into two categories. The first category involves arthroscopic repair of the anterior talofibular ligament (ATFL) using artificial materi
als or special suturing methods, including knotless suture anchor or InternalBrace techniques, double-anchor augmentation techniques, and
Lasso-Loop suture techniques for augmented repair. Studies show these can increase the post-repair strength of the ATFL but raise patient
medical costs. The second category is arthroscopic reconstruction, including anatomical reconstruction of the ATFL using autologous gracilis
tendon or semitendinosus tendon. While this improves ATFL strength, it partially disrupts the ankles anatomical structure, offers a smaller
arthroscopic operative space, increases surgical difficulty and duration, and may raise perioperative complication risks. Conclusion:Although
various arthroscopic techniques exist for CLAI repair, limitations such as increased cost, disruption of ankle anatomy, and longer surgery time
remain. The decision on whether and which repair technique to use for different patient types requires further evaluation through large-sample,
long-term, high-quality randomized controlled trials to comprehensively assess long-term efficacy and clinical benefits.
