Understanding Ankle Replacement Surgery

Ankle replacement surgery is used to treat arthritis of the ankle joint. It's advised for people with severe ankle arthritis. It also helps arthritis that has destroyed the ankle joint surfaces, or ankle pain that restricts daily activities. The damaged ankle joint is removed. It’s replaced with a metal or plastic implant.

The ankle joint

A joint is a place in the body where bones meet. The ankle joint is two joints. One is called the true ankle joint. The shinbone (tibia), fibula, and talus bones make up this joint. This joint is replaced during ankle replacement surgery. Parts of the tibia and talus are replaced.

Why ankle replacement surgery is done

The surgery may be a choice for people with arthritis of the ankle joint. Arthritis may make it hard for you to walk without pain. It may make it hard to do daily activities. Surgery is a choice when other treatments haven’t worked well enough. These may include exercises, medicine, bracing, injections, and heat or cold. Ankle replacement surgery can help stop the pain.

How ankle replacement surgery is done

Your ankle replacement surgery will be done by an orthopedic surgeon. The surgeon will make a cut (in incision) through the skin and muscle of your ankle. An incision may also be made on your foot. The damaged parts of your shinbone and talus will be removed. The artificial joint components will be attached to your shinbone and talus. A special type of cement may be used to hold them in place. A piece of plastic may be put between the new metal joint pieces. This is so they can glide easily against each other.

Risks of ankle replacement surgery

Every surgery has risks. The risks of this surgery include:

  • Infection

  • Damage to nearby nerves

  • Bleeding

  • Blood clots

  • Bones not joining together properly

  • Bones not lining up properly

  • New or worsening arthritis in nearby joints

  • Wearing out of the artificial joint

  • More surgery needed

Your risks vary based on your age and general health. For example, if you are a smoker or if you have low bone density, you may have a higher risk for certain problems. People with diabetes may also have a higher risk for problems. Talk with your healthcare provider about which risks apply most to you.
