Development And Validation Of A Finite Element Model To Predict Patello-Femoral Wear In TKA

Experimental patello-femoral (PF) and tibiofemoral (FT) wear tests can be used to quantify wear in an implant but these procedures are expensive and time consuming. Therefore, a validated numerical model could be useful to predict wear in less time with less cost. For these reasons, the aim of this study was to develop and validate a numerical methodology to predict PF wear in TKA. Initially, the wear model was calibrated using the results of an experimental roll-on-plane wear test. The developed wear model was applied to predict PF wear and validated comparing the numerical predicted wear with experimental wear results.status: publishe
