If my ankle gets “fused”, will I be able to walk normally again like I did before the arthritis set in?

Fusing bones is often a last resort when treating for arthritis. Fusing the bones is like welding them together so they are as one. As a result, their movement is very limited because instead of a moving joint, you have a solid bone mass.

So the quick answer is no, your ankle won’t be as flexible as it was before it developed arthritis. To understand this better, it would be best to discuss this with your doctor what your treatment options may be.
