Surgical treatment of chronic dislocation of the peroneal tendons.

Recent reports on the outcome of sports injuries have pointed out that ankle sprains may cause long term discomfort, this occasionally being due to peroneal tendon dislocation which may become chronic. The present paper reports a method, which includes deepening of the retromalleolar groove and at the same time maintaining the cartilagenous gliding layer. Long term follow-up (2 to 10 years) is presented on four patients. One of the patients returned successfully to international track and road races. In each case, the clinical result after the operation was successful, the ankles showing normal biomechanical functions.
