Figure 6.
(a) Boundary and loading conditions on the FE knee joint model: tied contact pair between (1) cartilage–bone, (2) ligament–bone and (3) tibia–fibula; contact pairs between (4) cartilage–meniscus and (5) cartilage–cartilage. The proximal femur was fixed in 6 degrees of freedom. A 374-N axial load was applied along the tibia, and varus/valgus bending moments, ranging from 0 to 15 Nm, were applied about the knee joint centre. (b) Anterior and (c) posterior views and of the knee joint FE model, displaying the hexagonal and tetrahedral mesh elements for the soft tissues and bones, respectively.
