Ankle Replacement is surgery to replace the damaged bone in the ankle joint. Artificial joint parts (prosthetics) are used to replace the bones. Still ankle replacement is not a common procedure and the research is ongoing to improve the results. In India the surgery is done by joint replacement surgeons who have trained in ankle replacement. Ankle replacement is a surgery where in a patient speific implant is put in place of the old ankle.
How Does The Ankle Replacement Surgery Work?
Ankle replacement involves replacing the natural surfaces of the ankle joint which have degenerated with an artificial cover known as prosthesis. The ankle replacement has three components. Two of the components cover the joint and in the middle there is a third, mobile component. This allows for greater movement and reduces the stress between the bone and the implants.
The component which covers the part of the ankle joint known as the tibia is flat. It is integrated into the bone with a short stem. The component which covers the part of the ankle joint known as the talus is curved and fixed into place with pegs. All the components are covered in a bioactive coating which encourages the patient’s own bone to grow into the artificial fixtures.
Advantages of Ankle Replacement Surgery:-
- Relieve pain and restore joint function in patients with end-stage degenerative joint disease resulting from osteoarthritis, traumatic arthritis or rheumatoid arthritis.
- It helps protect the surrounding joints (eg. subtalar joint) compared to an ankle fusion
- Gives a good useable range of movement of ankle
- Encourages a more normal walking gait pattern
