A schematic (A) shows the mechanical joints representing the hip and ankle degrees of freedom. The specimen is shown mounted in the rig (B) with the following components labeled: a. motor assembly, b. quadriceps clamp, c. femur dynamic reference body (DRB) used to track kinematics, d. patellar DRB, e. tibial DRB, f. tibial load cell.
