Abstract

A new method about reconstructing the finite element model of artificial knee joint is presented in this article after the research on reverse engineering (RE for short). Firstly, on the basis of the prosthesis prototype, IMAGEWARE and PRO/E are used to deal with point cloud of prototype and then prosthesis model is reconstructed; secondly, based on CT of human knee joint, distal femur (DF for short) and proximal tibia (PT for short) are built after processing image and regulating gray value; and finally all of the models built above are assembled in one order and exported finite element models, which forms the foundation of biomechanics analysis.
