Dislocation of the Peroneal Tendons

What is a dislocation of the peroneal tendons?

The peroneal tendons lie in a groove behind the bony bump on the outside of the ankle, held in place by strong bands of tissue called the peroneal retinaculum. If these bands are damaged, the tendons can slip out of their groove, resulting in a dislocation of the peroneal tendons. Physiotherapy plays an important role in the treatment and rehabilitation of this condition.

How does a dislocation of the peroneal tendons happen?

For the peroneal tendons to dislocate, the peroneal retinaculum must first be injured. This often happens when the foot and ankle are forcibly twisted inwards. While this mechanism commonly results in ankle ligament sprains, it can also damage the peroneal retinaculum, allowing the tendons to slip out of place.

What are the symptoms of a dislocation of the peroneal tendons?

You may experience a ‘popping’ sensation as the retinaculum is injured. This may be associated with swelling and tenderness behind the bony bump on the outside of the ankle. The peroneal tendons are no longer held down and, therefore, they may move out of the groove (dislocate) and remain out following the injury. This may be apparent when comparing the appearance of the outside of the injured ankle to the other ankle. Alternatively, the peroneal tendons may move out of the groove (dislocate) and over the ankle bone as the peroneal muscles are contracted and then return to their original position when the muscles are relaxed. This movement may be seen and felt as you point your toe. Additional symptoms may include:

  • Pain along the outside of the ankle
  • A feeling of instability or weakness in the ankle
  • Swelling and bruising around the affected area
  • A snapping or clicking sensation with ankle movements
  • Difficulty walking or bearing weight on the foot

What should I do if I have a dislocation of the peroneal tendons?

If you suspect that your peroneal tendons are dislocating you should arrange an assessment with a specialist. The physiotherapists at Physio.co.uk can confirm your diagnosis and refer you to an appropriate professional. In the meantime, to help reduce the swelling and pain in your ankle, you should follow the RICE regime (Rest, Ice, Compression, Elevation). This involves resting the ankle by avoiding activities that place stress on it, applying ice regularly to control swelling and pain, using compression such as an elastic bandage to help limit swelling, and elevating the ankle above heart level to reduce inflammation.

Physiotherapy treatment for a dislocation of the peroneal tendons.

Following surgery, your physiotherapist will rehabilitate your ankle to enable you to return to normal activity. Treatment often involves:

  • Pain management techniques
  • Gentle range of motion exercises
  • Progressive weight-bearing activities
  • Strengthening of the ankle and calf muscles
  • Balance and proprioception training
  • Sport-specific or activity-specific rehabilitation exercises

Could there be any long-term effects from a dislocation of the peroneal tendons?

If the peroneal tendons are dislocating, surgery is required to correct the problem. With appropriate treatment and rehabilitation, the outcome is generally very good, and in most cases there are no long-term effects following surgery.
