Anterior Talofibular Ligament Reconstruction could Produce Comparable Functional Outcomes with or without Calcaneofibular Ligament Reconstruction for Chronic Lateral Ankle Instability

CATEGORY: Ankle; Arthroscopy; Sports INTRODUCTION/PURPOSE: This study evaluates the effects on functional outcomes of with or without calcaneofibular ligament reconstruction when reconstructing the ATFL for chronic lateral ankle instability METHODS: This retrospective cohort study included 48 chronic lateral ankle instability patients with later ligament reconstruction that underwent either with or without a calcaneofibular ligament reconstruction using an ipsilateral free semitendinosus tendon autograft from June 2014 to October 2017. The Visual Analogue Scale score, the American Orthopaedic Foot & Ankle Society score, Karlsson Ankle Functional Score and Anterior Talar Translation in both groups were compared. RESULTS: All patients were followed up for at a mean of 30 months, Visual Analogue Scale score, the American Orthopaedic Foot & Ankle Society score, Karlsson Ankle Functional Score and Anterior Talar Translation between two the groups were not statistically significant different. CONCLUSION: There are no differences at 2.5 years in postoperative ankle function and stability when an ipsilateral free semitendinosus tendon autograft is used to manage CLAI with anterior talofibular ligament reconstruction with and without reconstructing the calcaneofibular ligament.
