ABSTRACT
Contact stress analysis of prosthetic implants has become a significant area of research in
recent years with increased demand for greater levels of stress analysis of products in the
preclinical phase. New techniques for contact pressure measurement have been developed
(FUJI Presensor, and Tekscan) and in addition improved contact algorithms have been
developed by finite element software developers. The current study uses the contact capabili-
ties of MARC software to investigate the contact stress levels occurring at the femoro-tibial
interface in a total knee joint replacement. The components are modelled initially using
