Objective

To introduce the surgical technique and clinical outcomes of arthroscopic anterior talofibular ligament (ATFL) repair using the Internal Brace and lasso-loop technique for chronic ankle lateral instability.

Methods

A retrospective study was performed on 29 patients who underwent all-arthroscopic ATFL repair with the Internal Brace and lasso-loop technique from January to August 2020. The patients included 24 males and five females, with a mean age of 30.17 years. Through the accessory anterolateral (AAL) portal, we drilled the bone tunnels and fixed the tape with 4.75 mm and 3.5 mm “SwiveLock” anchors and reattached the torn ligament by the lasso-loop technique.

Results

All 29 patients underwent all-arthroscopic procedures smoothly without serious complications, such as infection and important nerve or vessel injuries. There were eight cases of lateral malleolar avulsion fractures and ten cases of talus cartilage injury. The visual analog scale (VAS), Karlsson-Peterson, Tegner, and American Orthopedic Foot and Ankle Society (AOFAS) scores were used to evaluate the clinical consequences. All the patients were followed up for 18.66 ± 4.85 months on average. The average pre-operative VAS score was 4.69 ± 1.04, which was significantly higher than the average post-operative VAS score of 1.14 ± 1.56. At the final follow-up appointments, the averages of Karlsson-Peterson, AOFAS, and Tenger scores were 75.83 ± 9.44, 88.31 ± 6.81, and 6.93 ± 1.79, respectively, which was significantly higher than that before the operation.

Conclusion

This arthroscopic anterior talofibular ligament repair with the Internal Brace and lasso-loop technique achieves satisfactory clinical outcomes with the benefits of high safety and reliability for chronic ankle lateral instability.

关节镜下距腓前韧带内固定和套索环技术修复慢性踝关节外侧不稳

客观的

介绍关节镜下采用内固定和套索环技术修复距腓前韧带 (ATFL) 治疗慢性踝关节外侧不稳的手术技术和临床结果。

方法

对 2020 年 1 月至 2020 年 8 月接受全关节镜下 ATFL 修复的患者进行了一项回顾性研究。这些患者包括 24 名男性和 5 名女性，平均年龄为 30.17 岁。通过辅助前外侧 (AAL) 入口，我们钻了骨隧道并用 4.75 毫米和 3.5 毫米“SwiveLock”锚固定胶带，并通过套索环技术重新连接撕裂的韧带。

结果

所有 29 名患者均顺利完成了全关节镜手术，没有出现感染和重要神经或血管损伤等严重并发症。外踝撕脱骨折8例，距骨软骨损伤10例。视觉模拟量表 (VAS)、Karlsson-Peterson、Tegner 和美国骨科足踝协会 (AOFAS) 评分用于评估临床结果。所有患者平均随访18.66±4.85个月。术前平均 VAS 评分为 4.69 ± 1.04，明显高于术后平均 VAS 评分 1.14 ± 1.56。最后一次随访时，Karlsson-Peterson、AOFAS 和 Tenger 评分的平均值分别为 75.83 ± 9.44、88.31 ± 6.81 和 6.93 ± 1.79，显着高于术前。

结论

这种采用内部支撑和套索环技术的关节镜下距腓前韧带修复术取得了令人满意的临床结果，具有高度安全性和可靠性，可治疗慢性踝关节外侧不稳定。
