The operation is performed under general anesthesia. The orthopedic surgeon makes an incision over the affected knee. The patella (knee cap) is moved out of the way, and the heads of the femur and tibia are shaved to eliminate any rough parts and to permit a better adhesion of the prosthesis. The two parts of the prosthesis are implanted into the thigh bone and the tibia bone using a special bone cement.
