| Abstract: | Numerical analysis of FEM were made on the composite structures of tibia platform, which contained both fixed type interfaces of bone cement and growth of bone histocyte and metal and different characteristic biomaterials, for the corrected artificial knee joint with the function to compensate the anterior posterior crossed ligaments in unilateral and biolateral loads. The calculated results of stresses and displacements were valuable to the surgery of knee joint and device of new type of artificial knee joint. |
