Ankle replacement, or ankle arthroplasty, is a procedure performed to remove a problematic ankle joint and replace it with an artificial prosthesis. The prosthesis is made of two parts: the tibial component, which is the part that replaces the socket of the ankle, and the talus component, which replaces the top of the talus.
Generally, osteoarthritis, rheumatoid arthritis, bone fracture, or arthritis caused by previous ankle surgery necessitates this procedure.
Signs and Symptoms
Severe pain and loss of movement of the ankle. These symptoms indicate something more significant is going on in the ankle joint and should lead you to receive a full evaluation by your physician.
First, an incision is made through the skin on the front of the ankle. The nerves, blood vessels, and tendons are moved to the side to be protected. Next, an incision is made in the joint capsule that is around the ankle joint. The joint is opened and removed so that it can be replaced.
Next, the ends of the tibia, fibula, and talus are shaped so that the metal sockets may be inserted. Then, all pieces of the artificial joint are inserted. The ankle is tested to ensure that the prosthesis fits properly and allows proper movement.
To ensure that the prosthesis is fitted securely, two screws are placed through the fibula and tibia just above the prosthesis. Additionally, a bone graft is taken from bone that was previously removed and is grafted between the fibula and tibia to create a fusion. This prevents movement between the two bones that could cause the prosthesis to loosen.
