BACKGROUND Anterior talofibular ligament (ATFL) is the most easily injured or even broken of ankle sprain. Patients who fail to receive conservative treatment, resulting in persistent ankle swelling, painful and functional decline that it is so-called chronic lateral ankle instability (CLAI). It makes sense to investigate all-inside arthroscopic reconstruction of ATFL with InternalBrace™ for CLAI. MATERIAL AND METHODS We included 108 patients who underwent all-inside arthroscopic ATFL reconstruction with InternalBrace™ for CLAI from January 2018 to April 2020 through a retrospective study. Patients age ranged from 19 to 58 years (mean 35.6±8.7 years). Several elements are used to evaluate the clinical consequences of ankle function, including the American Orthopedic Foot and Ankle Society (AOFAS), Japanese Society for Surgery of the Foot Ankle-Hindfoot (JSSF), Kofoed, Tegner scores and complications, and the tilt angle of talus (TT) and the anterior displacement of talus (ADT) with stressing radiographs were taken to measure in follow-ups. RESULTS All 108 patients had all-inside arthroscopic procedures performed smoothly without serious complications. During the follow-up period (26.7±2.6 months on average), no recurrence of ankle instability and other serious complications happened. The AOFAS, JSSF, Kofoed, and Tegner scores significantly increased as time went by postoperatively, which proved statistically significant (P<0.01). Regarding stress-radiographic measurements, TT significantly decreased from (9.5±1.1)° preoperatively to (2.6±0.6)° at the latest follow-up (P<0.01), while ADT significantly decreased from (9.5±1.0) mm preoperatively to (2.6±0.6) mm at the latest examination (P<0.01). CONCLUSIONS All-inside arthroscopic ATFL reconstruction with the InternalBrace™ for CLAI is beneficial for ankle stability, allowing earlier return to activities.
距腓前韧带（ATFL）是踝关节扭伤中最容易受伤甚至断裂的韧带。如果患者未接受保守治疗，导致持续踝关节肿胀、疼痛和功能下降，即所谓的慢性外侧踝关节不稳定（CLAI）。因此，对 CLAI 患者采用 InternalBrace™全内镜 ATFL 重建具有重要意义。
我们回顾性分析了 2018 年 1 月至 2020 年 4 月采用 InternalBrace™全内镜 ATFL 重建治疗 CLAI 的 108 例患者。患者年龄 19~58 岁，平均 35.6±8.7 岁。采用美国矫形足踝协会（AOFAS）、日本足踝外科协会（JSSF）、Kofoed、Tegner 评分和并发症评估踝关节功能的临床结果，并在随访时摄应力位 X 线片测量距骨倾斜角（TT）和距骨前位移（ADT）。
108 例患者均顺利完成全内镜手术，无严重并发症。平均随访 26.7±2.6 个月，无踝关节再不稳定和其他严重并发症。术后 AOFAS、JSSF、Kofoed 和 Tegner 评分逐渐升高，差异有统计学意义（P<0.01）。应力位 X 线片测量 TT 由术前的（9.5±1.1）°逐渐减小至末次随访时的（2.6±0.6）°（P<0.01），ADT 由术前的（9.5±1.0）mm 逐渐减小至末次随访时的（2.6±0.6）mm（P<0.01）。
InternalBrace™全内镜 ATFL 重建治疗 CLAI 有利于踝关节稳定性，可更早恢复活动。
