Ankle replacement surgery is the replacement of a damaged ankle joint with an artificial implant. Ankle replacement surgery is a procedure to replace this damaged joint to eliminate this pain and swelling. Typically, the procedure takes place under general anesthesia. Your surgeon will make an incision in your ankle to access the affected joint. Next, your surgeon will remove the damaged parts of your tibia and talus bones. Your surgeon will attach artificial metal joints to the remaining bone surfaces, with a piece of plastic inserted between them.
