In the most severe cases of osteoarthritis, not relieved by medical treatments and rehabilitation, the damaged parts of the joint can be replaced by prosthesis, known as ankle arthroplasty.
The first step consists of removing the osteophytes and the damaged cartilage and then preparing the bone that will receive the prosthesis.
The ankle prosthesis consists of three parts : the upper part is fixed to the base of the tibia by a small stem inserted in the spongy bone, the lower part is fixed to the place of the talus by a screw.
Between these pieces of metal, place a plastic liner, which will allow a harmonious sliding as in the normal articulation.
