In vivo measurement of 3-D kinematics of total knee arthroplasty (TKA) is expected, as one of important technique for design of the artificial knee joint in future generation. Therefore, in vitro analysis of polyethylene wear, contact pressure are possible in femorotibial joint and fomoropatellar joint. The study aimed to develop the full six degrees of freedom (DOF) motion simulator for the artificial knee joint using parallel link 6-DOF actuator and air survo cylinders. In this report, we evaluate the method of simulation and usefulness of simulator. The tibial insert was mounted on the 6-DOF actuator and controled internal/external and abduction/adduction rotation, and lateral/medial and anterior/posterior translation. The femoral component was mounted on a jig and control flexion/extension rotation and loading by two air survo cylinders. The contact area and the contact pressure were measured for 2 types of TKA by a tactile sensor under a typical gait condition.
