Outline of Final Research Achievements

The mechanical stress of the knee during ambulation has a profound influence on the treatment outcome for osteoarthritis (OA) at the knee. Therefore, it is important to clarify the knee joint biomechanics and evaluate the kinematics and kinetics of the knee. The purpose of this study was to determine the kinematics and kinetics of the knee and develop a measurement system for the mechanical stress of the knee. In this study OA knees showed increase in the varus angle and the external knee adduction moment during gait. In addition a measurement system for the mechanical stress of the knee was established using Kinect sensor and Wii balance board. Therefore, this system can provide an easy and objective evaluation for the mechanical stress of the knee in a clinical situation.
