Total hip arthroplasty (THA) is performed to replace the biological hip joint with an artificial joint for patients who suffer from rheumatoid arthritis or osteoarthritis of the hip joint. The hip joint simulator, which can generate the desired hip joint angle and the joint contact force, has been developed in order to evaluate the performance of the artificial hip joint. We generate the realistic behavior of artificial hip joint dislocation using the simulator considering the hip joint contact force which consists of the muscle force around the hip joint and the floor reaction force. In this paper, we discuss the effect of the hip contact force on artificial hip joint dislocation.
