Abstract
Implants are compared with suitable material combinations. UHMWPE material is used for interface component and TZP is used for tibia plateau component (lower component) and intercondylar groove (upper component) in knee joint. The finite element analysis is performed for the knee implant for 600 N and for knee implant components for 600 N and 1,000 N body weights are considered. This study reveals the fact in case of any misalignment of components; the finite element analysis is performed for components individually in order to determine maximum possible von Mises stresses. Grid convergence is performed in the present analysis.
