Ankle replacement, also known as ankle arthroplasty, begins with the application of anesthetic or a nerve block to the ankle. An incision is made and the affected bone and cartilage is removed. Prosthetic pieces are then inserted to replace the removed tissue and the ankle’s new range of motion is checked. Additional repairs are then made to ensure your foot and ankle properly align. Recovery from this procedure usually takes between six to 12 months.
While this procedure does maintain a generally natural range of motion for the ankle, it’s best to maintain a healthy weight and avoid high-impact physical activities to prevent damage to the prosthetic parts. If these parts do become overly damaged over time, you may require an additional surgery.
