Abstract Taking the common dislocation failure after total hip arthroplasty as research object, the visual motion analysis module of hip prosthesis based on Adams was designed and developed. This module can construct the hip prosthesis model with different design parameters, simulate motions for various behavior condition, and acquire motion range of hip prosthesis. The kinematics data of the lower limbs during action of daily living was obtained by using the optical motion capture system. Comparing the theoretical motion data obtained by module and the experimental kinematics data of the natural joint, this paper studied the relationship between the dislocation of the hip prosthesis and the action of daily living. The results unveil that it is of high risk performing high flexion activities, especially squatting activity. The research results would be helpful for clinical rehabilitation, prosthesis design and optimization.
