FINITE ELEMENT ANALYSIS MODEL VALIDATION TO EVALUATE TRABECULAR METAL TIBIAL CONES USED IN REVISION TOTAL KNEE ARTHROPLASTY

摘要

A comparative finite element analysis (FEA) model was developed to predict the relative stresses and strains in Zimmer NexGen Trabecular Metal Tibial Cone components. The FEA predictions were compared to measurements obtained through physical testing. The model was validated for its ability to correctly rank the order of predicted strain in the components under applied load.
