Autologous split peroneus longus lateral ankle stabilization.

Lateral ankle instability is a common clinical entity, and a variety of surgical procedures are available for stabilization after conservative management fails. Herein the authors reviewed outcomes after performing autologous split peroneus longus lateral ankle stabilization, using a previously described surgical technique to anatomically recreate the anterior talofibular and calcaneofibular ligaments. Twenty-five consecutive patients from 2 surgeons' practices underwent reconstruction between March 2007 and January 2011 with a minimum follow-up of 12 (range 12 to 51) months (mean 29.5 months). Follow-up interviews demonstrated 92.0% good or excellent outcomes with only 8.0% rating the outcome as fair and none as poor; 92.0% had no recurrent sprains or difficulty going up or down hills; 88.0% related no difficulty with uneven ground. The authors conclude that the autologous split peroneus longus lateral ankle stabilization results in a stable ankle with a low rate of complications and high patient satisfaction.
