ABSTRACT

Biotribology is considered an important aspect in designing artificial joints. It has been reported that the revision rate of total knee replacement for patients under 60 years was five times higher than that for patients over 70 years, more than 20% of which were caused by wear of the tibial insert. In the last decade, experimental and computational knee wear simulators have been developed and applied in the preclinical evaluation of implant designs and the understanding of the polyethylene wear mechanisms of bearing materials to replace physical wear simulators. In this chapter, state-of-the-art computational biotribology modeling approaches and theoretical modeling of artificial knee joints are introduced. Additionally, the limitations of the current model and future directions are discussed.
