Welcome to Optimum Recovery Rehab Physical Therapy & Rehabilitation's patient resource about Peroneal Tendon Problems.
Problems affecting the two peroneal tendons that lie behind the outer ankle bone (the lateral malleolus) are common in athletes. These problems mainly occur in the area where the two tendons glide within a fibrous tunnel behind the lateral malleolus.
This guide will help you understand:
- how peroneal tendon problems develop
- how doctors diagnose the condition
- what can be done to treat this problem

Anatomy
The peroneals are two muscles and their tendons that lie along the outside of the lower leg bone (the fibula) and cross behind the lateral malleolus (the outer ankle bone). The term medial refers to a point closer to the center of the body. So the ankle bump on the inside edge of the ankle (closest to your other ankle) is the medial malleolus. The term lateral refers to structures furthest from the center. Major muscles that support the lateral part of the ankle are the peroneus longus and the peroneus brevis.
The tendons of these two muscles pass together in a groove behind the lateral malleolus. (Tendons attach muscles to bones.) The tendons are kept within the groove by a sheath that forms a tunnel around the tendons. The surface of the tunnel is reinforced by a band of tissue called a retinaculum. Contracting the peroneal muscles makes the tendons glide in the groove like a pulley. The pulley action causes the foot to point (plantarflexion) and (eversion).
The connects to a bump on the base of the fifth metatarsal. This spot can be felt midway down the outer edge of the foot.
The lies behind and below the peroneus brevis tendon. It wraps down and under the foot by way of the cuboid bone, the outer tarsal bone just in front of the heelbone (the calcaneus). The peroneus longus tendon angles forward under the sole of the foot and connects to the bottom of the main bone of the big toe. This tendon stabilizes the arch of the foot when walking.

Causes
Why do I have this problem?
Peroneal tendon problems mostly occur where the tendons glide within the pulley behind the lateral malleolus. Their movement can cause irritation of the lining of the tendons. This condition is called . The irritation can also occur after an ankle injury, such as a blow to the outside of the ankle or an ankle sprain.
Repetitive ankle motions in sports, such as running and jumping, can lead to wear and tear on the tendons inside the groove. A high arch puts extra tension on the peroneal tendons within the groove and has also been found to cause peroneal tendon problems.
Peroneal tendon problems commonly occur from an ankle sprain. During the typical inversion ankle sprain, the foot rolls in. This type of injury sprains or tears the ligaments that support the lateral part of the ankle. The forceful stretch on the peroneals when the foot rolls in can also cause a lengthwise tear in the peroneal tendons.
An inversion ankle sprain can also cause the peroneal tendons to momentarily slip out of the groove. This is called subluxation. Peroneal tendonitis often occurs during the recovery period after an ankle sprain. Because the ankle is unstable, the peroneals may need to work harder to give needed support to the damaged lateral ankle ligaments. The overwork sets them up for subluxation.

In some patients, a peroneal tendon problem is caused by degenerative changes in the tendons themselves rather than by inflammation around the tendons. The tendon itself becomes abnormal. Doctors call this condition tendonosis.
In tendonosis, the tendon becomes weakened. Tendons are made up of strands of a material called . (If you think of a tendon as a nylon rope, the collagen is the nylon strands.) in a tendon causes a loss of the normal arrangement of the collagen fibers that join together to form the tendon. Some of the individual strands of the tendon become jumbled due to the degeneration, some fibers break, and the tendon loses strength.
Over time, the tendon thickens as scar tissue tries to repair the damaged tendon. The area of tendonosis in the tendon is weaker than normal tendon. The weakened, degenerative tendon may tear. This usually causes a lengthwise in the peroneal tendons rather than a rupture. These splits or tears are most common in the peroneus brevis tendon, probably because it lies in front of the peroneus longus. It is more vulnerable to friction because it rubs against the groove in the fibula bone.
Symptoms
What do peroneal tendon problems feel like?
Patients with peroneal tendon problems usually describe pain in the of the ankle or just behind the lateral malleolus. This pain commonly worsens with activity and eases with rest. Patients may have swelling behind or under the lateral malleolus. They may notice more pain when pressure is applied along the tendons.
Diagnosis
The diagnosis of peroneal tendonitis is usually made by examination of the ankle. The physical examination helps determine where the tendons are inflamed, ruptured, or degenerated. Your Physical Therapist at Optimum Recovery Rehab Physical Therapy & Rehabilitation will move your ankle into different positions, checking the peroneal tendons by holding your foot up and out against the therapists downward pressure. Stretching the foot up and in can also be used test whether the tendons hurt.
Some patients may be referred to a doctor for further diagnosis. Once your diagnostic examination is complete, the Physical Therapists at Optimum Recovery Rehab Physical Therapy & Rehabilitation have treatment options that will help speed your recovery, so that you can more quickly return to your active lifestyle.
Our Treatment
Nonsurgical treatment for peroneal tendon problems helps control symptoms. Surgery is usually not considered until it has become impossible to control symptoms without it.
Non-surgical Rehabilitation
Even if you don't require surgery, you may need to follow a program of rehabilitation exercises. The Physical Therapists at Optimum Recovery Rehab Physical Therapy & Rehabilitation can create a program to help you regain normal ankle function, improving strength and coordination your ankle.
Initial treatments may involve resting and protecting the sore tendons. We may need to immobilize your foot and lower leg in a short-leg walking boot for two to four weeks. In less severe cases, we may have you use a stirrup ankle brace, arch support, or lateral heel wedge to take tension off the sore tendons.
Your Physical Therapist may use heat, ice, and ultrasound treatments to reduce pain and swelling. Stretching, strengthening, and ankle coordination exercises are sometimes added as symptoms ease.
Post-surgical Rehabilitation
Patients with peroneal tendon problems are usually placed in a short-leg cast for four to six weeks after surgery, then a special walking boot may be worn for another four weeks. Rehabilitation after surgery can be a slow process. Although recovery varies for each patient, as a guideline, you may need to attend Physical Therapy sessions at Optimum Recovery Rehab Physical Therapy & Rehabilitation for one to two months, and you should expect full recovery to take up to four months.
Your first few Physical Therapy treatments at Optimum Recovery Rehab Physical Therapy & Rehabilitation are designed to help control pain and swelling from the surgery. Our therapist may use ice and electrical stimulation treatments during your first few Physical Therapy sessions, in addition to massage and other hands-on procedures to ease muscle spasm and pain. We also provide treatments to help improve ankle range of motion without putting too much strain on the healing tendons.
It is possible that, after about four weeks you may be able to incorporate more active exercise. Your Physical Therapist will slowly add exercises improve the strength in your peroneal muscles. We will also help you regain position sense in the ankle joint to improve its overall stability.
At Optimum Recovery Rehab Physical Therapy & Rehabilitation, our goal is to help you keep your pain under control, improve your range of motion, and maximize strength and control in your ankle. When you are well under way, regular visits to our office will end. Although we will continue to be a resource, you will be in charge of doing your exercises as part of an ongoing home program.

Physician Review
Your doctor may order X-rays to make sure there is no fracture or other problem. A magnetic resonance imaging (MRI) scan of your ankle may also be done. MRI images can show if there is abnormal swelling or scar tissue in the tendons and can also show lengthwise tears in the tendons.
Your doctor may also prescribe medications. Anti-inflammatory medications can help ease pain and swelling and get you back to activity sooner. These medications include common over-the-counter drugs such as ibuprofen.
In rare cases, cortisone can be injected into the sore tendons to relieve symptoms that won't go away. Cortisone is a powerful anti-inflammatory medication. Because there is a risk that cortisone will cause a tendon to rupture, doctors are very cautious about injecting cortisone into the peroneal tendons.
Surgery
Tendon Release
When the lining of the tendon is painful and inflamed (as in tenosynovitis), the goal of surgery is to remove the irritated tissue from around the tendon. This operation is called tendon release. This procedure is done by carefully dividing the tendon sheath that encloses the tendon. Once the , the surgeon around the tendon. The sheath is not stitched back together. The gap in the sheath will eventually fill in with scar tissue. The skin is closed with sutures.
Debridement
The procedure for surgically treating tendonosis is similar to the method used for tenosynovitis. However, extra measures are taken to thoroughly remove (debride) the degenerated tissue around and within the involved tendon.
Tendon Repair
Tendonosis may require repair if a preoneal tendon is split down its length. This type of tear mainly affects the peroneus brevis. The surgeon fixes this problem by first around the tendons. If the split is smaller than one-third the width of the tendon, the torn portion may simply be removed. Larger splits are sutured along the length of the tendon. The tendon sheath is , and the skin is closed with sutures.
