Abstract

For an adequate design of total knee replacements, knowledge about stresses and lubrication conditions is vital. Within this study, a numerical model is presented and validated with experimental data. Good agreement between model predictions and experimental data as well as a strong influence of fluid, material and geometry assumptions as well as transient effects were found. It was demonstrated that the rheological synovial fluid properties have a decisive impact on the tribological behavior.
