Study on a Practical Use of a Knee Prosthesis which is capable of attaining Complete Flexion

本研究的目的是评估我们的新膝关节假体的运动学和耐久性，该假体是为了实现完全屈曲而开发的，如日本式SEIZA。为了从日本政府的MHLW获得将其放入患者体内的许可证，我们必须从运动学和动力学的角度证明其具有足够的性能。因此，我们进行了各种分析和实验，即，三维模型分析、尸体研究、运动学测量、有限元分析和光弹性研究，从而总结其结果。

The objective of this study was to assess the kinematics and durability of our new knee prosthesis which was developed to attain a complete flexion such as Japanese style SEIZA. In order to get license from the MHLW of the Japanese Government for putting it in a patient, we had to demonstrate that it has enough performance to do so from kinematic and kinetic viewpoints. Thus, we carried out various kinds of analyses and experiments, i.e., 3D model analysis, cadaveric study, kinematic measurement, FEM analysis and photoelastic study, thereby summing up their results.
