Abstract	A three-dimensional musculoskeltal model of the human knee is being developed to investigate the forces placed on the four major knee ligaments as a result of muscle contraction. This computational knee model includes the femur, tibia, and patella, seven major muscles, four knee ligaments, and the patellar tendon. A constrained forward dynamic simulation is performed by using EMG data to estimate muscle forces. The ligament forces estimated by the model are verified by means of a robotic-cadaver experimental setup in which the knee flexion angle of a cadaver specimen was controlled by a robot. Estimated muscle forces were dynamically applied to the cadaver knee as it was flexed/extended through a specified range of motion. The ligament strain calculated by the model is compared to the strain measured experimentally and to values found in literature to verify the accuracy of the model.
