This review summaries the knowledge of the treatment of peroneal nerve palsy. Isolated peroneal nerve palsy is often seen after fracture of the knee or knee dislocation. In cases with chronic peroneal nerve palsy and foot drop, tendon transfer of the posterior tibial muscle tendon to the dorsum of the foot is a possibility to be considered. This procedure is indicated for isolated peroneal nerve palsy with good ankle mobility, good strength of the posterior tibial muscle and no chance of spontaneous remission.
