Hip joint and knee joint replacements are helping people of all ages live pain- free, active lives. When only some of the joint is damaged, a surgeon may be able to repair or replace just the damaged parts. When the entire joint is damaged, a total joint replacement is done. To replace a total hip or knee joint, a surgeon removes the diseased or damaged parts and inserts artificial parts, called prostheses or implants.
Computer navigation provides the surgeon with the real-time 3-D images of the mapped patient’s knee and the surgical instruments during surgery. The data for the images is provided by the infrared sensors fixed to the bones of the knee and the surgical instruments.
