Tendon graft fixation (the left ankle). (A) Viewed from the AM portal, the graft is fixed with an appropriate-diameter 15-mm long bioabsorbable interference screw in the talar tunnel first. Subsequently, the ATFL graft is tensed by pulling the suture anchor thread at the fibular tunnel. Then, the strands are tied, with the ankle approximately in the 30° to 45° plantar flexion position to avoid postoperative plantar flexion restriction. Finally, the graft is fixed with an interference screw in the calcaneal tunnel, with the ankle in the neutral position. (B) Viewed from the AAL portal, the tendon graft finally becomes the complete triangle-shaped. Both panels are from patient 1. (AAL, accessory anterolateral; AM, anteromedial; ATFL, anterior talofibular ligament; CFL, calcaneofibular ligament; LTCL, lateral talocalcaneal ligament.)
