Understanding Peroneal Tendonitis: Diagnosis, Treatment, and Prevention

January 27, 2023

Peroneal tendonitis is a painful condition caused by inflammation of the tendons in the foot. It can be caused by overuse, repetitive motion, or direct trauma to the area. Symptoms include pain along the outside of your ankle and calf that worsens when running or walking on uneven surfaces.

If you are experiencing these symptoms it’s important to seek out medical advice as soon as possible for proper diagnosis and treatment of peroneal tendonitis.

In this blog post we’ll discuss what peroneal tendonitis is, how to diagnose it, treatment options available, prevention strategies and management techniques so you can get back on your feet again quickly.

What is Peroneal Tendonitis?

Peroneal Tendonitis is an inflammation of the peroneal tendons, which are located on the outside of your ankle. It can be caused by overuse or repetitive activities such as running, jumping, and dancing. The condition can also occur due to direct trauma to the area or a sudden change in activity level.

Definition of Peroneal Tendonitis:

Peroneal tendonitis is an inflammation of the peroneal tendons that run along the outside of your ankle joint. This condition causes pain and swelling in this area and can limit mobility if left untreated.

Common causes of peroneal tendonitis include overuse from activities such as running, jumping, and dancing; direct trauma to the area; or a sudden increase in activity level without proper warm-up exercises beforehand.

Other potential causes may be attributed to improper footwear for certain activities, tight calf muscles that put additional strain on these tendons, flat feet (overpronation), high arches (supination), poor biomechanics when walking/running/jumping/dancing etc., age-related degeneration (tendinopathy) or arthritis in this region.

Key Takeaway: Peroneal tendonitis is an inflammation of the peroneal tendons on the outside of your ankle caused by overuse, direct trauma or a sudden increase in activity level. Common causes include: improper footwear, tight calf muscles, flat feet (overpronation), high arches (supination) and poor biomechanics when walking/running/jumping.

Diagnosis and Treatment of Peroneal Tendonitis

Diagnostic Tests for Peroneal Tendonitis:

Diagnosing peroneal tendonitis typically involves a physical examination and imaging tests. During the physical exam, your doctor will check for tenderness, swelling, or other signs of inflammation in the area around your ankle. Imaging tests such as X-rays or an MRI may also be used to rule out any underlying causes of pain that could be contributing to your symptoms.

Non-Surgical Treatments for Peroneal Tendonitis:

Non-surgical treatments are often recommended as the first line of treatment for peroneal tendonitis. These treatments can include rest, ice therapy, anti-inflammatory medications (NSAIDs), stretching exercises, and physical therapy. Your doctor may also recommend wearing a brace or splint to reduce stress on the affected area while it heals.

Stem cell therapy is an excellent treatment for chronic pain and treating peroneal tendonitis. This is a non-surgical treatment that uses your body’s stem cells to target and heal the pained area.

If non-surgical treatments fail to provide relief from symptoms after several weeks or months of use, surgery may be recommended by your doctor. Surgery is usually only considered if there is evidence of significant damage to one or both tendons due to chronic overuse injuries or tears in the tissue caused by trauma.

The type of surgery performed depends on the severity and location of injury but commonly includes debridement (removal) of damaged tissue and repair/reconstruction using sutures or grafting techniques with donor tissues such as fascia latae (connective tissue).

Prevention and Management of Peroneal Tendonitis

Tips to Prevent Peroneal Tendonitis:

The best way to prevent peroneal tendonitis is by taking steps to avoid overuse or strain of the affected area. This includes stretching and strengthening exercises, wearing supportive shoes, and avoiding activities that may cause excessive stress on the tendons. Additionally, it is important to take regular breaks from physical activity and rest when needed.

Exercises to Manage Pain from Peroneal Tendonitis:

Stretching exercises can help reduce tension in the affected area and improve flexibility of the muscles around the tendon. Strengthening exercises can also be beneficial as they will help support the joint and reduce stress on the tendons. It is important not to push yourself too hard during these exercises as this could further aggravate your condition.


However, with the right treatment plan and preventive measures, it is possible to reduce pain and improve function. Stem cell therapies such as PRP, stem cell therapy, and MLS laser therapy may offer an alternative approach for those looking for non-surgical solutions to their peroneal tendonitis.
