During knee flexion and extension the ACL and PCL help to coordinate the movement and rotation of the knee by constraining the sliding and rolling motions at the joint. In the natural knee the femur pivots about the medial condyle and the femur tends to roll back on the tibia with increasing flexion . The purpose of this study was to observe if and how rollback occurs in the natural knee using the lowest point (LP) method, and to understand how anterior-posterior (AP) motion is related to flexion angle in the natural knee. A better understanding of natural knee femoral rollback will influence future design of total knee arthroplasties.
