In the contemporary aging society, joint diseases are serious problem. When a disease occurred, it expects that serious problems happen. We thought that it was important to expect those problems by the FEM analysis. We constructed three-dimensional model of FEM model by CT image of knee joint. Used FEM software is Ansys7.0. Shell element, SHELL63 (3〜4 nodal points) were used for modeling. Model of knee joint constructed femur, tibia, patella and fibula. Total number of element is 3630 and nodal points are 1849. On material constants of bone, Young's modulus with 10GPa Poisson's ratio with 0.3. And it was analyzed contact of joint by FEM.
