Prosthesis and methods for unicompartmental and total knee arthroplasty

摘要

A knee joint prosthesis, comprising at least one femoral component and at least one tibial component. The femoral component having a first portion adapted for fixable attachment to a distal end of a femur and a second portion formed with a bearing surface. The femoral component is sized so as to permit attachment to the femur of a patient without severing at least one the cruciate ligaments. The tibial component has a first surface that is adapted to cooperate with a patient's tibia, while a second surface of the tibial component is adapted to cooperate with the femoral component. The tibial component is sized so as to permit attachment to the patient's tibia without severing at least one of the cruciate ligaments.
