An ankle fusion gives reliable, lasting pain relief for a worn ankle joint, often through a keyhole approach. The ankle no longer bends up and down, but the foot's other joints take over much of that movement, and most people walk comfortably afterwards.
When is ankle fusion considered?
Ankle fusion is considered for painful end-stage ankle arthritis when injections, bracing, footwear changes and activity modification no longer give enough relief.
Can I avoid surgery?
What happens during the procedure
The worn cartilage is removed from the ankle joint
The bones are positioned for comfortable walking
Screws or plates hold the ankle while it fuses
The leg is protected in plaster or a boot until the bones heal
Recovery timeline
- First 6–10 weeks — usually protected or non-weight-bearing
- 10–12 weeks — weight-bearing increases if X-rays show healing
- 3–6 months — walking distance and strength build
- 6–12 months — full recovery and swelling improvement continue
Risks & complications
Risks include infection, non-union, hardware irritation, nerve symptoms, blood clots, altered gait and stress on nearby joints over time.

Questions & answers
The ankle joint itself will not move, but surrounding foot joints provide enough movement for most people to walk comfortably.
Fusion is durable and suits many active patients. Replacement preserves movement but is not right for everyone.
Some cases can be done arthroscopically, depending on deformity, bone quality and previous surgery.
Driving depends on side, comfort, braking control and insurer guidance. It is often not until weight-bearing and control have returned.
