Anatomic Reconstruction of Lateral Ankle Ligaments and Both Peroneus Tendons After Open Fracture Dislocation of the Ankle: A Case Report

Extensive soft tissue defects of the ankle are an uncommon but challenging problem that require a combination of reconstructive options. We report the case of a complex injury involving the skin, lateral ankle ligaments, and peroneal tendons that were anatomically reconstructed. A 15-year-old girl was injured in an automobile accident resulting in extensive soft tissue defects and marked instability of her right ankle. The lower two-thirds of the anterior talofibular ligament (ATFL) had segmental defects, and calcaneofibular ligament (CFL) was completely torn, and both peroneal longus and brevis tendons were severely damaged. Initial debridement was performed on the day on injury. Two weeks after injury, the ATFL and CFL were reconstructed using a semitendinosus autograft and suture tape augmentation. Both peroneal tendons were reconstructed using a gracilis autograft. The skin defect (10 × 10 cm) was covered with an anterolateral thigh flap. After removing a short leg cast at 3 weeks postoperatively, the patient started range of motion exercises without using any brace. Weightbearing was allowed at 4 weeks. At the 24-month follow-up examination, she had returned to her preoperative level of work and sports activities.
