Peroneal Tendonitis

Paroneal tendonitis is inflammation around or within the peroneal tendons in the foot and ankle. These tendons are located behind the fibula, on the outside of the ankle, and help pull the foot up and outward.

What causes peroneal tendonitis?

Paroneal tendonitis is caused by repetitive activity, microscopic tears in the tendon, or partial larger tears in the tendon and can be acute or chronic. They are most commonly found in people who participate in sports.

What are the symptoms of peroneal tendonitis?  

People will notice tenderness over the outer aspect of their ankle and may even see some swelling. Difficulty walking is also a common complaint with peroneal tendonitis.  

How is peroneal tendonitis evaluated? 

Plain radiographs are the initial diagnostic study of choice for peroneal tendonitis. An MRI may be needed to evaluate the extent of the tendon damage. 

What treatment options are available for peroneal tendonitis? 

The non-operative treatment of peroneal tendonitis involves modification of running activities and the institution of cross-training to decrease the repetitive traction load through the hindfoot.  This can be combined with anti-inflammatory medications.  For patients who are significantly symptomatic, the use of a short term walking boot may help to settle their symptoms.  Corticosteriod injections are sometimes considered as well. Operative treatment involves an extensive debridement and repair of the inflamed tissue.

What can I expect after undergoing successful treatment for peroneal tendonitis?

With mild disease, return to normal activity is expected. With severe tendon involvement, limitations may be present.
