Peroneal Tendonitis, Peroneal Tenosynovitis

There are a number of tendons in the foot which helps control movement while you are mobile (walking, running). The two major tendons that go around the outside of the ankle are called the peroneal tendons. They are important tendons because they balance the ankle and the back of the foot and prevent the foot from turning inwards repetitively, causing lateral (inversion) ankle sprains. Overuse and injury of these tendons causes weakness and mobility dysfunction. Normally, these tendons pass behind the bone on the outside of the ankle (fibula). In some instances, injury can cause the natural restraining mechanism to fail and allow the tendons to slip over the bone (Peroneal tendon dislocation). They are slightly weaker than the muscles and tendons on the inside of the ankle and are prone to injury as the ankle turns, rolls or becomes sprained.

Peroneal Tendon Dislocation / Tearing

Tearing or dislocation can occur in one or both of these tendons. This leads to pain, swelling, sensitivity and a sense of instability behind the outside of the ankle. They can also pop out of the supporting ligaments that hold them in place (a dislocation); once this occurs, continuous or recurrent dislocation and tearing is inevitable without immediate attention and repair. Stitching and at the worst, tendon replacement may be required for patients suffering from torn or dislocated peroneal tendon(s).
