RESUMO
BACKGROUND: Anatomic graft reconstruction of the anterior talo-fibular ligament is an alternative for patients who are bad candidates for standard procedures such as a Broström-Gould reconstruction (high-demand athletes, obesity, hyperlaxity or collagen disorders, capsular insufficiency or talar avulsions). The purpose of this study is to describe an all-inside arthroscopic technique for ATFL reconstruction, and the results in a series of patients with chronic ankle instability. METHODS: We reviewed patients with chronic ATFL ruptures treated with an all-inside arthroscopic allograft reconstruction of the ATFL, with a minimum 2-year follow-up. Twenty-two patients with lateral ankle instability were included. Mean follow-up was 34±2.5 months. RESULTS: The mean AOFAS score improved from 62.3±6.7 points preoperatively to 97.2±3.2 points at final follow-up. Three patients suffered complications: one case each of ankle rigidity, superficial peroneal nerve injury and fibular fracture. CONCLUSIONS: Chronic ATFL injuries are amenable to all-inside arthroscopic allograft reconstruction fixed with tenodesis screws. This procedure simplifies other reported techniques in that it facilitates identification and bone tunnel placement of the talar ATFL insertion.
