Which of the following statements is true in motions of the knee?

knee extension
d. The axis for flexion and extension is clinically approximated as directed through the center
of the lateral and medial condyles of the femur
c. Terminal rotation of the knee is a locking mechanism observed during the last 20 degrees of
knee extension
