Purpose The purpose of our study is to evaluate the clinical results of anatomical reconstruction of the lateral ligaments with semitendinosus allograft.
Methods Thirty-six patients with chronic lateral instability underwent anatomical reconstruction of the lateral ligaments of the ankle with semitendinosus allograft. The American Orthopaedic Foot and Ankle Society Ankle-Hindfoot Scale score (AOFAS score) and the Karlsson score were used to
evaluate the clinical results before and after surgery.
Results A total of 35 patients (97.2 %) (36 ankles) were followed up for a mean of 37.9 months. The mean AOFAS score improved from 42.3±4.9 points preoperatively to 90.4± 6.7 postoperatively. The mean Karlsson score improved from 38.5±3.2 preoperatively to 90.1±7.8 postoperatively
