Comparison of Arthroscopic Surgery Versus Open Surgical Repair of the Anterior Talofibular Ligament: A Retrospective Study of 80 Patients from a Single Center

BACKGROUND: This retrospective study from a single center aimed to compare the safety and clinical outcomes of arthroscopic surgery vs open surgical repair of the anterior talofibular ligament (ATFL). MATERIAL/METHODS: We randomly divided 80 patients with ATFL injury divided into 2 groups: an open surgery group and an arthroscopic group. The operation time, intraoperative bleeding volume, and the postoperative recovery time of all patients were analyzed. The anterior displacement and talus tilt angle, the American Orthopedic Foot and Ankle Society Ankle-Hindfoot Score (AOFAS), the Jersey Shore Science Fair (JSSF) ankle-hindfoot scale score, and the Karlsson Ankle Functional Score (KAFS) were compared at 6 months, 1 year, and 2 years after surgery. We collected data on the incidence of postoperative complications during follow-up. All significant results were supported with a P value. RESULTS: The operation time, intraoperative bleeding volume, and postoperative recovery time in the arthroscopic group were better than in the open group (P<0.05). The AOFAS, JSSF, and KAFS in the arthroscopic group were better than in the open group at 6 months after the operation (P<0.05). The AOFAS, JSSF, and KAFS scale scores were not significantly different between the 2 groups at 1 year and 2 years after the operation (P<0.05). CONCLUSIONS: The findings from this retrospective study showed that the use of arthroscopic surgical repair of the ATFL is a safe minimally invasive technique with reduced blood loss and surgical duration and good clinical outcomes.
