Ankle Injuries: Ankle Sprain
Peroneal tendon injury is a relatively rare cause of ankle pain. The peroneal tendons help keep the foot balanced and prevent ankle-twisting injuries. From trauma to the bone or soft tissues on the outside (lateral aspect) of the ankle, the peroneal tendons can subluxate (slip out of place) and cause pain and swelling along the lateral aspect of the ankle. It can also cause weakness and instability. Treatment initially consists of immobilization, ice, and compression. If the peroneal tendons continue to subluxate, surgery may be considered to repair the tendons back to their original location.
