What is Tendonitis?

Tendonitis is an inflammation of the tendon. A tendon is a band of tissue that connects a muscle to a bone. The most common tendons that get injured in the foot and ankle are the Achilles Tendon, Peroneal Tendons, and Posterior Tibial tendon. Symptoms of tendonitis include:

  • Pain
  • Swelling
  • Warmth to the touch

Causes and Symptoms of Tendon Injuries

Tendon injuries may be acute (occurring suddenly) or chronic (developing over a period of time). They most commonly occur in individuals who participate in sports that involve repetitive ankle motion. In addition, people with arches that are too high or too low are at risk for developing tendonitis.


Because tendon injuries are sometimes misdiagnosed and may worsen without proper treatment, prompt evaluation by your doctor is advised. To diagnose a tendon injury, your doctor will examine the foot and look for pain, instability, swelling, warmth, and weakness of the ankle. In addition, an x-ray or other advanced imaging studies may be needed to fully evaluate the injury. Dr. Hoffmann and Dr. Lagdaan will also look for signs of an ankle sprain and other related injuries that sometimes accompany a tendon injury. Proper diagnosis is important because prolonged discomfort after a simple sprain may be a sign of additional problems.

Non-Surgical Treatment

Treatment depends on the type of peroneal tendon injury. Options include:

  • Immobilization. A cast or splint may be used to keep the foot and ankle from moving and allow the injury to heal.
  • Medications. Topical, oral or injected anti-inflammatory drugs may help relieve the pain and inflammation.
  • Physical therapy. Ice, heat, or ultrasound therapy may be used to reduce swelling and pain. As symptoms improve, exercises can be added to strengthen the muscles and improve range of motion and balance.
  • Bracing. Dr. Hoffmann or Dr. Lagdaan may provide a brace to use for a short while or during activities requiring repetitive ankle motion. Bracing may also be an option when a patient is not a candidate for surgery.

When is Surgery Needed?

In some cases, surgery may be needed to repair the tendon or tendons and perhaps the supporting structures of the foot. Your doctor will determine the most appropriate procedure for the patient’s condition and lifestyle. After surgery, physical therapy is an important part of rehabilitation.

This information has been prepared by the Consumer Education Committee of the American College of Foot and Ankle Surgeons, a professional society of over 6,000 foot and ankle surgeons. Members of the College are Doctors of Podiatric Medicine who have received additional training through surgical residency programs. The mission of the College is to promote superior care of foot and ankle surgical patients through education, research and the promotion of the highest professional standards.
