Finite Element Modeling

Finite element modeling (FEM) is a sophisticated mathematical tool that enables us to predict the mechanical response of structures exposed to different external loads and constraints. We have developed sophisticated finite element models to supplement the results predicted by our experimental studies.

The Meniscus
Our FEM of the meniscal structures allows for better understanding and visualization of the impact of surgical procedures on the loading and movement of menisci in vivo.

Other FE Models
Our experimentally validated FEM of the knee joint, which includes all inter-capsular structures, predicts strain in the collateral and cruciate ligaments. We have also developed a model of the retinacular structures of the knee to determine the effect of total knee replacement design on strain in the lateral retinaculum.

Total Hip Replacement
A FEM of the trunnion and femoral head can be used to study how local WEAR AND FRETTING TRIBO-CORROSION is impacted by design and loading factors such as:

• angular mismatch tolerance
• frictional conditions
• angle of loading
• magnitude of external torque
• magnitude of assembly load
• magnitude of gait load
