What is Peroneal Tendon Disorder?

Aug 22, 2023 | Ankle Conditions, Peroneal Tendon Disorders


Peroneal tendon disorder, also known as peroneal tendinopathy or peroneal tendonitis, is a relatively common condition that affects the peroneal tendons in the ankle. These tendons play a crucial role in stabilizing the ankle and enabling outward movement of the foot. When these tendons become inflamed or damaged, it can lead to pain, discomfort, and decreased mobility. In this article, we will delve into the causes, symptoms, diagnosis, and treatment options for peroneal tendon disorder.

Anatomy of Peroneal Tendons

The peroneal tendons are located on the outer side of the ankle, behind the bony protrusion called the lateral malleolus. These tendons are divided into two main parts: the peroneus longus and the peroneus brevis. The peroneus longus runs along the bottom of the foot and helps to maintain the arch, while the peroneus brevis runs along the back of the ankle and aids in stabilizing the foot during movement.

Causes of Peroneal Tendon Disorder

Peroneal tendon disorder can arise from various factors, including:

  1. Overuse or Repetitive Strain: Activities that involve repetitive ankle movements, such as running, jumping, or dancing, can strain the peroneal tendons and lead to inflammation.
  2. Ankle Instability: Ankle sprains or instability can cause the peroneal tendons to work harder to stabilize the joint, increasing the risk of tendon damage.
  3. Poor Footwear: Ill-fitting shoes or shoes without proper arch support can contribute to abnormal foot mechanics, placing additional stress on the peroneal tendons.
  4. Abnormal Foot Structure: Individuals with high arches or flat feet may have an increased risk of peroneal tendon disorder due to altered biomechanics.
  5. Trauma: Direct trauma to the tendons or ankle can lead to tendon damage or inflammation.

Symptoms of Peroneal Tendon Disorder

Common symptoms of peroneal tendon disorder include:

  1. Pain: Pain on the outer side of the ankle or along the course of the tendons is a hallmark symptom.
  2. Swelling: Swelling and tenderness around the peroneal tendons may be present.
  3. Weakness: Weakening of the ankle and decreased stability can result from damaged peroneal tendons.
  4. Clicking Sensation: Some individuals may experience a clicking or snapping sensation when moving the ankle.

Diagnosis and Treatment

Diagnosing peroneal tendon disorder typically involves a thorough physical examination, medical history review, and possibly imaging tests such as X-rays, ultrasound, or MRI to assess the extent of tendon damage.

Treatment strategies for peroneal tendon disorder may include:

  1. Rest and Immobilization: Giving the tendons time to heal by avoiding activities that exacerbate the condition.
  2. Physical Therapy: Targeted exercises to strengthen the peroneal muscles and improve ankle stability.
  3. Orthotics: Custom-made shoe inserts or orthotic devices can help correct foot mechanics and reduce strain on the tendons.
  4. Medications: Nonsteroidal anti-inflammatory drugs (NSAIDs) can help alleviate pain and inflammation.
  5. Bracing or Taping: Using braces or taping techniques to provide support and protect the tendons during movement.
  6. Corticosteroid Injections: In some cases, corticosteroid injections may be used to reduce inflammation and pain.
  7. Surgery: Surgical intervention is considered if conservative treatments fail. Procedures may involve tendon repair, tendon transfer, or release of tight tissues.


To minimize the risk of peroneal tendon disorder:

  • Wear appropriate footwear with proper arch support.
  • Gradually increase the intensity of exercise and avoid sudden changes in activity.
  • Perform regular stretching and strengthening exercises for the ankle and foot muscles.
  • Listen to your body and rest when you experience pain or discomfort.


Peroneal tendon disorder can significantly impact an individual’s mobility and quality of life. Recognizing the causes, symptoms, and treatment options can facilitate early intervention and prevent the condition from worsening. If you suspect you have peroneal tendon disorder, it is essential to consult a medical professional for an accurate diagnosis and personalized treatment plan.
