A schematic illustrating a human cadaveric knee joint being tested on the robotic/universal force-moment sensor testing system at preselected angles of knee flexion, providing 5 degrees of freedom joint motion (AP, anterior-posterior; FE, flexion-extension; IE, internal-external; ML, medial-lateral; PD, proximal-distal; VV, varus-valgus) at each prescribed angle of knee flexion.
