Description: A six degree of freedom model was utilized to study the motion of the loaded human knee joint, with emphasis placed on the role of the posterior cruciate ligament (PCL) in that motion. Unlike previous studies, where the joint was loaded statically, continuous measurements were taken throughout the range of motion, full extension (zero degrees) to 110 degrees flexion. Several different loading conditions were studied, with loading conditions varying to simulate the natural body forces (i.e. the normal condition) and hamstrings-deficient or quadriceps-deficient conditions. The motion of the knee in the normal configuration was then compared to the motions after the PCL was surgically severed. Finally, the PcL was reconstructed, the tests were repeated, and the results were compared to the normal configuration. The joint reaction forces on the knee were calculated using the normal knee configuration as the loaded condition. These comparisons will aid in determining the best method of PCL reconstruction.
