| Outline of Final Research Achievements |
This study developed a unified model of human musculo-skeletal system and artificial joint to predict human motions after the knee replacement surgery. This model allows us to compute the muscle and ligament forces during a motion, and to compute the stress distribution between the components of the artificial knee joint. The validity of the model was verified by comparing simulation results with measurement data of an actual patient. Based on the finite element analysis, dominant parameters of the artificial knee geometry were extracted, which were applied to a design method of an artificial knee shape. Moreover, a method to estimate a patient’s motion control of the knee joints as the joint viscoelasticity was proposed to predict the patient motion after the knee replacement.
