In posterior stabilized total knee arthroplasty, researchers ascertained the extent of the effect of the femoral component’s sagittal alignment on kinematics and biomechanics. Findings suggested that in knee joint mechanics, the femoral component sagittal position is an important factor. A stable reconstruction of the knee extensors’ mechanism was demonstrated by the flexion of femoral component. Neutral-to-mild flexed femoral component position may be considered without concerns of anterior notching of the femoral cortex.
