Treatment algorithm for chronic lateral ankle instability.

INTRODUCTION ankle sprains are a common sports-related injury. A 20% of acute ankle sprains results in chronic ankle instability, requiring surgery. Aim of this paper is to report the results of a series of 38 patients treated for chronic lateral ankle instability with anatomic reconstruction. MATERIALS AND METHODS thirty-eight patients were enrolled in the study. Seventeen patients underwent a surgical repair using the Brostrom-modified technique, while the remaining underwent anatomic reconstruction with autologous or allogenic graft. RESULTS at a mean follow-up of 5 years the AOFAS score improved from 66.1 ± 5.3 to 92.2 ± 5.6. DISCUSSION the findings of this study confirm that anatomic reconstruction is an effective procedure with satisfactory subjective and objective results which persist at long-term follow-up along with a low complication rate. No differences, in term of clinical and functional outcomes, were observed between the Brostrom-modified repair and the anatomic reconstruction technique. LEVEL OF EVIDENCE level IV.
