Cross shear, contact pressure and contact area in a simplified TKR wear simulation

Record type: Conference or Workshop Item (Poster)

Current wear algorithms, which are functions of contact kinematics (ie cross shear (CS)) and contact pressure (CP), predict wear in total knee replacement (TKR) with moderate success. Recent pin-on-disk experiments, however, have demonstrated a dependence of wear on CS and contact area (CA), but not CP. When the CP term is removed from wear algorithms, their predictive power is unaffected. To elucidate the relative contributions of CP, CS, and CA in TKR we performed a wear simulation on flat tibial inserts under two values of maximum load and two levels of IE rotation. In this simplified model, we hypothesized that wear would depend strongly on CA and CS but not CP
