Behind the prominent bump on the outside of your ankle are two tendons known as the peroneal tendons. They run down from the outside of your leg below the knee and go behind the ankle and into the foot. Behind the ankle they are securely ‘tied down’ within a smooth sheath that allows the tendons to move freely, stabilising the foot and helping it to turn outwards.
Yes. It’s important to have the ankle assessed by a surgeon as soon as possible to make sure that the correct treatment is started. If you ignore the problem, it can cause other more serious problems including a complete tendon rupture (tear), which is more difficult to treat.
It’s important to have an accurate diagnosis by a specialist as this type of injury can often be mistaken for a simple ankle sprain. Where there is a long term degenerative problem, X-rays can sometimes show a flake of bone from the ankle if the tendon has dislocated or calcium has built up. You may also have an ultrasound scan to check for splits or dislocation.
You may be advised to take anti-inflammatory medication. Further treatment depends on the specific type of problem:
Reducing your activity, resting, and having a boot fitted that immobilises your foot is often successful but very active patients, especially keen athletes, sometimes find this unsatisfactory
Dislocated tendons or a tear in a tendon
Non-operative treatment: reducing activity, resting, and having a boot fitted that immobilises your foot (as with acute tendinitis) can help. You may also be referred for physiotherapy to help stabilise the peroneal tendon function.
Surgery: if you still experience symptoms, you may need to have surgery to repair a tear or split in the tendon or to relocate the tendons and repair the sheath. This has an 80-90% success rate, with many patients able to return to their previous sporting activities.
Non-operative treatment: long term symptoms can be improved with rest, immobilisation and gradual introduction of physiotherapy and supervised exercise. Shoe wear can be modified if necessary
If non-operative treatment does not relieve the symptoms, you may be offered a procedure to clear out the damaged tissue (debridement) from around the tendon area
