Normal knee joint kinematics with regard to total knee replacement.
Every knee has its individual envelope of motion. The joint surfaces, the ligaments and the articular capsule determine the range of motion. In walking, stability is mainly provided by the muscles. Malalignment is the usual reason for failure in knee replacement with PCA prostheses. Preoperative planning is essential for operative success.
