Total knee replacement or arthroplasty is realigning of the joint (bone end surfaces), with artificial parts called prostheses. There are three components used in the artificial knee . The femoral component is made of metal and covers the end of the thigh bone. The tibial component covers the upper surface of tibia. Between the two is hard plastic (polyethylene) component.
For the patients with a significant knee arthritis and with the worn out cartilage which is covering the bone within the knee, replacement of the knee with an artificial joint can offer excellent pain relief and restoring of the knee function.
In our clinic we use computer navigation (computer assisted surgery – CAS) for knee replacement. Infra red camera registers the points taken in the knee joint. Than the computer creates virtual model of the knee. In the real time we put resection jigs on the tibia, and than on the femur and navigate the cuts. That allows us very precise resection of the bones, usually within 1 milimeter and 1 degree of deviation from desired position. Computer also helps us with the soft tissue balance. That is important for load transfer in the joint. All that should improve function and longevity of the knee. We have implanted more than 200 knees with computer assistance in our clinic so far.
Rehabilitation is the same as after the partial knee replacement procedure.
