Understanding peroneal tendon problems and your options.

The peroneal tendons run down the outer side of the ankle. They help keep the ankle steady and turn the foot outward. They can become inflamed, worn, torn, or slip out of place.

Runners and people with high arches or unstable ankles often have these problems. Early care can prevent a small irritation from becoming a tear.

Diagnosis and care

How we treat peroneal tendon problems.

Step 1 · Diagnosis

We feel along the tendons and test their strength. We may move your ankle to see if the tendon slips. Ultrasound can show the tendon moving, and an MRI shows tears and swelling.

Step 2 · Treatment

Rest, a brace, or a short time in a boot can calm the tendon. Physical therapy builds strength and balance. Orthotics or shoe changes can reduce pressure on the outer ankle. Ice and gentle stretching can also help settle pain.

When a tendon is torn or keeps slipping, surgery can repair it or deepen the groove where it sits. Choices depend on how much of the tendon is hurt.

Recovery

What to expect over time.

Mild irritation may improve in four to twelve weeks. Surgery usually needs a few months of protected healing and therapy.

When to book

Do not wait it out.

See a podiatrist if the outer ankle hurts and swells or you feel a snap. Come in soon after a sprain if the ankle still feels weak.

Why does my outer ankle snap?

Can peroneal tendon pain be mistaken for a sprain?

Yes, the two can feel much alike. A careful exam and imaging tell them apart.
