Chronic ankle instability is one possible course in the natural history of acute ankle sprain. It represents 10% to 30% of sprain sequelae. Surgical treatment is reserved for patients with persistent ankle instability after rehabilitation causing disabling discomfort. The technique of ligamentoplasty using the peroneus brevis according to Castaing is the most popular in Morocco. The simplicity of the gesture and its good results encouraged us to pursue this path. This is a retrospective study of 24 patients who underwent fibular brevis ligamentoplasty according to Castaing between January 2017 and June 2020. The minimum follow-up was one year. The evaluation of the patients was based on the Karlson score and the “Ankle score” Molander and Olerud. Patients are satisfied or very satisfied with the intervention in 80% of cases reviewed. The functional results of our patients are comparable to those published in the literature. Removal of the peroneus brevis transplant does not seem to have any impact on ankle stability. Patients maintain satisfactory foot eversion with comparable force to the opposite side. The evolution of osteoarthritis of the ankle does not seem significant after this surgery. The weak point of our study is the number of patients lost to follow-up, this is linked to the youth of the operated population and to the recruitment of the nationwide service.
