Surgical Management of Lateral Ankle Instability: Modified Broström-Gould Versus Arthroscopic Allograft Reconstruction of the Anterior Talofibular and Calcaneofibular Ligaments. A Randomized Stratified Clinical Trial.

What this Trial Is About

This research aims to determine whether arthroscopic reconstruction with allograft offers real benefits compared to the modified open Broström-Gould technique for treating chronic lateral ankle instability. The study will use the clinical AOFAS scale to measure effectiveness and safety, and also assess health outcomes, patient pain levels, complication rates, and recovery time. It is a prospective, randomized, controlled clinical trial with two parallel groups, stratified by age and activity level. The trial compares two surgical methods: one group will receive the modified Broström-Gould open surgery, which rebuilds damaged ligaments using the patient's own tissue through an incision on the fibula's side, while the other group will undergo arthroscopic reconstruction using tendon allografts from tissue banks, performed through small incisions with arthroscopy. Both techniques are being evaluated for their outcomes and safety. Participants diagnosed with chronic lateral ankle instability will be followed for 12 months after surgery, with evaluations including clinical scales, pain assessments, and monitoring for complications. The total study period includes recruitment over 24 months and follow-up for a year, aiming to assess differences in recovery and return to normal activities. The study is led by Universidad Francisco de Vitoria and is expected to complete by 2028.
