Peroneal Tendonopathy: (Ankle)

Peroneal tendinopathy is a condition that affects the peroneal tendons, which run along the outside of the ankle and connect the lower leg muscles to the foot. These tendons help stabilize the ankle and support movements such as walking, running, and changing direction. When the tendons become irritated from overuse or repetitive stress, they can develop small injuries that lead to pain and swelling.

This condition is most commonly seen in athletes who run, jump, or play sports that involve frequent side-to-side movements, but it can also affect anyone who regularly places extra stress on the ankle. Risk factors include high arches, frequent ankle sprains, or spending long periods on uneven surfaces.

The most common symptom is pain along the outer side of the ankle. This pain may feel sharp during activity or present as a dull ache at rest. Swelling and tenderness are often present, and symptoms typically worsen with exercise or prolonged activity. Many people also describe a sense of weakness or instability, as if the ankle could “give way.” Walking on uneven ground or pushing off the foot can make the discomfort more noticeable.

In some cases, the pain may linger over time and become chronic if the tendons are continually stressed without proper recovery. Recognizing the signs of peroneal tendinopathy early is important so that patients can make changes to their activities and prevent further tendon irritation.
