Peroneal tendon instability is a condition in which the peroneal tendons, which run along the outside of the ankle and foot, are not held in place properly and are prone to dislocation or subluxation (partial dislocation). This can cause pain, weakness, and instability in the ankle and foot.
Peroneal tendon instability is often caused by a combination of factors, including ankle sprains, chronic ankle instability, and anatomical abnormalities that affect the stability of the peroneal tendons.
Symptoms of peroneal tendon instability can include pain and tenderness along the outside of the ankle and foot, a feeling of snapping or popping in the ankle, weakness and instability, and swelling and stiffness.
Treatment for peroneal tendon instability may include non-surgical options such as physical therapy to strengthen the ankle and foot muscles, bracing or taping to provide additional support, and modification of activities to avoid aggravating the condition.
In some cases, surgical intervention may be necessary to repair or reconstruct the damaged peroneal tendons, particularly if non-surgical treatments are not effective or the instability is severe.
It is important to consult with a healthcare professional if you are experiencing symptoms of peroneal tendon instability, as early diagnosis and treatment can help prevent further damage and improve overall outcomes. With appropriate care, most individuals with peroneal tendon instability can expect to make a full recovery and return to their normal activities.
