Anatomic Reconstruction of the Lateral Ankle Ligaments Using a Split Peroneus Brevis Tendon Graft

Abstract

Fifteen patients with recurrent inversion ankle sprains and documented lateral ankle instability were treated with an anatomically oriented ligament reconstruction using a split peroneus brevis tendon graft. This recon struction is designed to augment repair of the anterior talofibular and calcaneofibular ligaments without re stricting subtalar motion. Of the 12 patients available for long-term followup, all were functionally improved, with no recurrences of instability. Stress radiographic exami nation at followup confirmed that mechanical stability had been restored in all ankles. Eversion strength and subtalar joint motion were maintained after surgery. We recommend this procedure in patients who require aug mented reconstruction of the lateral ankle ligaments.
