Surgery is an option for people with AS when a joint is extensively damaged or pain is very severe. Surgery can help reduce pain, restore joint function, and improve mobility.

People with advanced or severe AS may need surgery to replace a badly damaged joint with an artificial joint. It is often a knee or the hip joint (but not the spine) that is replaced, and in many cases, the end result of severely damaged joints is a total hip joint replacement. After surgery, many people have less pain and are better able to perform their usual activities.

Surgery is not an option for everyone. Discuss the risks and benefits with your doctor.
