Recurrent peroneal tendon dislocation-the current concept of management.

The peroneus muscles, consisting of the peroneus longus (PL) and peroneus brevis (PB) tendons, are vulnerable to injury at anatomically specific sites or within tendon sheaths. Peroneal tendon dislocation (PTD) is often misdiagnosed as a lateral ankle sprain as it occurs at a lower frequency than a lateral ankle sprain. Anatomical variations in the retromalleolar groove, soft tissue overstuffing, and presence of accessory peroneal muscles contribute to the etiology of PTD.
