Reconstruction for lateral ligament injuries of the ankle

Abstract

Seventy-six patients (83 ankles) with chronic lateral instability of the ankle were treated by a simple reconstructive operation, namely, a subperiosteal release on the distal part of the lateral malleolus. The released flap, including the insertion of both the anterior talofibular and the calcaneofibular ligaments, was reattached to the malleolus more proximally. Seventy-five patients (82 ankles) were examined at a mean of 24 months (range 12 to 70) after operation. In 78 ankles (95%) the result was excellent or good. Forty-four of the 51 patients (86%) whose sporting activities were restricted before operation had no restriction at follow-up. Recurrence of instability occurred in one ankle, following a further injury two years after operation.
