Abstract
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.
