Peroneal Tendon Injuries

In the foot, there are two peroneal tendons. They run side-by-side behind the outer ankle bone. The main function of the peroneal tendons is to stabilize the foot and ankle and protect them from sprains. Peroneal tendon injuries may be acute (occurring suddenly) or chronic (developing over a period of time). They most commonly occur in individuals who participate in sports that involve repetitive ankle motion. In addition, people with higher arches are at risk for developing peroneal tendon injuries.
