摘要
Purpose. To report the outcome of a technique combining direct anatomic reconstruction of the anterior talofibular ligament (ATFL) with augmented reconstruction using the peroneus brevis tendon fixed by a bio-absorbable interference screw. Methods. 13 men and 2 women aged 17 to 36 (mean, 24) years with recurrent inversion injuries of the right (n= 5) and left (n= 10) ankles underwent lateral ankle reconstruction by a single surgeon. All patients had a positive anterior drawer test and heel eversion stress test, and some degree of tenderness to palpation over the anterolateral joint capsule. All patients had complete or partial tear of the ATFL and the calcaneofibular ligament, except for one. The torn ligaments were repaired anatomically and reinforced with a split peroneus brevis tendon rerouted through the fibula and fixed with a bioabsorbable interference screw. The outcome was assessed using the American Orthopaedic Foot and Ankle Society (AOFAS) ankle and hindfoot score and the Foot and Ankle Outcome Score (FAOS) at 6 months. Results. The mean time from injury to surgery was 40.5 months. The mean follow-up duration was 13.6 (range, 6-26) months. No patient had surgical or wound complications. The mean AOFAS ankle and hindfoot score was 91.5 (median, 93; range, 79-100). The mean FAOS was 78.8 (median, 77; range, 61100). 10 patients had no limitation in both daily and recreational activities; 3 had limitation in recreational activities, and 2 had limitation in both. 12 patients had normal and 3 had moderate limitation in hindfoot motion. One patient had hindfoot instability. Conclusion. The combination of augmented and direct anatomic reconstructions enables early mobilisation despite limitation in hindfoot motion and is a viable option for chronic hindfoot instability.
