3D Modelling and numerical simulations of menisci in normal and osteoarthritic human knee joint

This paper presents 3D virtual modeling of the menisci in the human knee joint, based on CT sections performed on the human knee joint. CT images were processed using advanced modeling and simulation methods as Space Claim and Design Modeler integrated application under Ansys Workbench software package. By using Finite Element Analysis, the stresses and displacements from normal menisci, but also from those affected by osteoarthritis, are studied for the cases of 5 degrees valgus deviation of the mechanical axes of the knee. The study concludes with a comparison between the results obtained from the analysis performed for the healthy menisci, on the one hand, and for the damaged ones, on the other hand.
