Therefore, studying the design parameters that are involved in the backside wear process is an important task that may lead to improvement in new total knee replacements. In the present study, a finite element model was developed to predict the backside micromotion along the entire modular interface. Both the linear elastic constitutive model and non-linear J\n                    <jats:sub>2<\/jats:sub>\n                    -plasticity constitutive model were considered in the finite element model for polyethylene and were corroborated against published results obtained from displacement controlled knee simulator wear tests. The finite element simulation with the non-linear J\n                    <jats:sub>2<\/jats:sub>\n                    -plasticity constitutive model was able to more accurately predict backside micromotion, while the linear elastic constitutive model was not. The developed finite element model (including the non-linear J\n                    <jats:sub>2<\/jats:sub>\n                    -plasticity constitutive model) was then applied to assess the effects of the tibial tray locking mechanism design (dovetails versus full-peripheral design) and different levels of interference fit on insert micromotion. The developed finite element model, implementing the non-linear J\n                    <jats:sub>2<\/jats:sub>\n                    -plasticity constitutive model, was shown to successfully predict clinical amounts of backside micromotion and could be used for the design and development of total knee replacements for the reduction of backside micromotion and wear.\n
