Peroneal Tendinopathy

Peroneal Tendinopathy Blog

Peroneal Tendinopathy, also called peroneal tendinitis, is a relatively rare but painful tendon injury that results from damage and degeneration of a peroneal tendon in the foot. The condition is most often associated with running, but basketball players, dancers and other athletes in sports that involve jumping and landing are also prone to the condition. PT is characterized by pain that begins near the ankle at the outside of the foot, and runs up the outer lower leg.

Peroneal Tendon Anatomy

Each foot has two peroneal tendons, longus and the brevis, and tendinopathy can occur in either or both tendons. The tendons connect the peroneus longus and the peroneus brevis muscles to the outer portion of your foot. The peroneal muscles and tendons work to roll your foot outward, stabilize your foot during physical activities, and work with your calf muscles to help you rise up on your toes.

Causes of Peroneal Tendiopathy

Damage to the peroneal tendons often occurs from overuse of the muscles during daily running, sports practice, rehearsals and performance. Injuries are most common in people with high arches, which places greater stress on the peroneal tendons. High arches are considered an asset in dancers, placing them at greater risk. Faster running speeds also increase peroneal tendon workload, and peroneal tendinopathy often accompanies an ankle sprain. The condition worsens with continued activity and improves with rest.

Symptoms of Peroneal Tendinopathy include:

  • Outer ankle pain when walking or running
  • Pain when at rest, particularly at night
  • Pain when loading the foot
  • Increased pain when turning the ankle inward or outward
  • Increased pain with ankle flexion
  • Ankle licking and snapping sounds
  • Decreased ankle and foot strength
  • Reduced range of motion

Diagnosis of Peroneal Tendinopathy

To differentiate peroneal tendinopathy from other sources of foot pain, a through health history and physical exam will be performed. At NYDNRehab, we use dynamic diagnostic ultrasound to visual the internal structures of your foot and ankle in real time, with feedback from the athlete facilitating an accurate diagnosis.

Other diagnostic tests and assessments may include:

  • ankle range of motion analysis
  • video gait analysis
  • assessment of movement mechanics
  • posture evaluation
  • evaluation of running shoes

Once the therapist has confirmed an injury to the peroneal tendon, an individualized treatment plan will be designed. Treatment may include:

  • pain management with ice and NSAIDs
  • ESWT (extracorporeal shock wave therapy)
  • strengthening exercises
  • flexibility training
  • postural correction
  • gait retraining

In this instance, an athlete was originally diagnosed with minor quadriceps muscle strain and was treated for four weeks, with unsatisfactory results. When he came to our clinic, the muscle was not healing, and the patients’ muscle tissue had already begun to atrophy.

Upon examination using MSUS, we discovered that he had a full muscle thickness tear that had been overlooked by his previous provider. To mitigate damage and promote healing, surgery should have been performed immediately after the injury occurred. Because of misdiagnosis and inappropriate treatment, the patient now has permanent damage that cannot be corrected.

The most important advantage of Ultrasound over MRI imaging is its ability to zero in on the symptomatic region and obtain imaging, with active participation and feedback from the patient. Using dynamic MSUS, we can see what happens when patients contract their muscles, something that cannot be done with MRI. From a diagnostic perspective, this interaction is invaluable.
