Ankle replacement or fusion?
For arthritis that has worn the ankle down to bone, these are the two main operations. Both can relieve pain. Neither is right for everyone.
| Question | Replacement | Fusion |
|---|---|---|
| What is done | Worn surfaces are replaced with metal and plastic parts. | The worn surfaces are removed and the bones are held with plates or screws until they heal into one bone. |
| Ankle motion | Still bends up and down. | No longer moves at that joint. |
A review of modern studies found no clear difference between the two in overall complication or revision rates. The better choice depends on your alignment, bone quality, the joints around the ankle, your health, and what you need the ankle to do. Read about ankle arthritis and the treatments that come first.
