Recurrent dislocation of the peroneal tendon is infrequent but often the injury is a disabling one, and the result of conservative treatment is unsatisfactory. Dislocation of these tendons may be the result of a congenitally shallow groove in the lateral malleolar or of a complete abscence of the groove and the dislocation may be present at birth or may be caused by trauma. We are reporting one case of bilateral recurrent dislocation of the peroneal tendons with- out any history of trauma in which disturbed superior peroneal retinaculum was reconstructed by transposition of the calcsneofibular ligament to the lateral side of the peroneal tendons. The calcaneal insertion of the calcaneofibular ligament was mobilised with a small bone block and reinserted in its bed after the transposition. After a follow up of 13 months, the result was satisfactory.
