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.
目的: 总结目前慢性踝关节外侧不稳（chronic lateral ankle instability，CLAI）的解剖修复治疗研究现状及进展。.
方法: 查阅国内外关于CLAI的解剖修复治疗的文献，并进行分析整理和总结。.
结果: 目前CLAI解剖修复术式主要为Broström术及其改良术式，此类术式操作简便，近、中、远期随访均显示满意临床疗效，且并发症发生率低。目前，带线锚钉技术、关节镜技术均逐渐用于Broström术及其改良术式中，并能获得较好近期疗效，远期疗效有待进一步观察。.
结论: Broström术及其改良术式是治疗CLAI有效、便捷、安全方法。在生物力学和动态解剖学研究基础上进行个性化修复方案设计是进一步研究方向。.
