Recurrent dislocation of peroneal tendons is a relatively rare ankle problem with numerous described surgical treatments which make the orthopaedic surgeons baffled in choosing the appropriate procedure. An 18 year old girl with a two years history of recurrent peroneal dislocation was treated successfully using plantaris tendon for delta-shape reconstruction of superior peroneal retinaculum. Her recovery was uneventful without any major complications or recurrence except surgical site tenderness and mild swelling for 5 months after surgery making a delta shaped retinaculum using plantaris tendon effectively prevents the dislocating peroneal tendons.
