What is it?
The peroneal tendons run behind the bony bump on the outer side of the ankle and help keep the ankle stable. They can become thickened and painful (tendinosis), tear, or slip out of their groove (subluxation).
What causes it?
- Ankle sprains.
- A high-arched foot.
- Overuse, particularly in sport.
Common symptoms
- Pain and swelling behind the outer ankle bone.
- A snapping or popping feeling.
- Weakness or instability of the ankle.
How is it diagnosed?
Your surgeon will examine the ankle, and an ultrasound or MRI scan shows the tendons.
Things you can do now
- Rest from the activity that brings on pain
- Wear an ankle brace for sport
- Do balance and strengthening exercises
- Use supportive footwear
Treatment
Treatment is tailored to your individual needs, symptoms and goals. Depending on your situation, it may include rest and a boot, an ankle brace, physiotherapy and surgery to repair the tendons, deepen their groove or correct a high arch.
Mr Jeyaseelan will talk you through the options that are right for you at your consultation.
When to see a specialist
- Pain or swelling behind the bone on the outside of the ankle persists
- You feel a snapping or clicking behind the ankle
- The ankle feels unstable
What to expect
Many cases settle with rest, a brace and physiotherapy. Tears or tendons that keep slipping out of place often need surgical repair.
