Total ankle replacement involves the surgical removal of a dysfunctional painful ankle joint and its replacement with prosthetic parts. The purpose of total ankle replacement is to relieve pain and restore joint function in patients with medically refractory, end-stage degenerative joint disease resulting from conditions such as osteoarthritis, post-traumatic osteoarthritis, or rheumatoid arthritis.

Arthrodesis is the fusion of a joint. This is an alternative procedure to the total ankle replacement. It does not require prior approval.

Arthroplasty is surgery to relieve pain and restore range of motion by realigning or reconstructing a joint.

Orthosis (plural orthoses) / orthotic – an orthopedic appliance or apparatus used to support, align, prevent, or correct deformities or to improve function of movable parts of the body. Some people with ankle conditions will use orthoses before moving to a surgical alternative.
