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

这项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的屈曲，如日式癫痫发作。为了获得日本政府MHLW的许可，把它放在病人身上，我们必须证明它有足够的性能，从运动学和动力学的角度来看。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，并总结了他们的结果。

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.
