[ADVANCES IN ANATOMICAL REPAIR OF CHRONIC LATERAL ANKLE INSTABILITY].

Objective: To summarize the current status and progress of the treatment of chronic lateral ankle instability (CLAI).

Methods: The literature about the anatomical repair of CLAI at home and abroad was reviewed and summarized.

Results: Broström and its modified operations are the most common surgical treatment of CLAI. The operations showed satisfactory clinical outcomes in the short-, medium-, and long-term follow-up and low complication rate. Suture anchor technique and arthroscopic techniques are gradually used in Broström and its modified operations with satisfactory short-term effectiveness, but long-term effectiveness needs further observation because of the limitation of the short clinical application time.

Conclusions: Broström and its modified operations are effective, convenient, and safe to treat CLAI. Based on the researches of biomechanics and dynamic anatomy, the more personalized design of the rehabilitation program is the further research direction.
