Structural Simulation of a Bone-Prosthesis System of the Knee Joint.

Bone structure is an extremely significant parameter; in Figure 17 we show a prosthesis touching mostly spongy bone (Figure 18(a)) and the same prosthesis placed on cortical bone (Figure 18(a)): the maximum equivalent von Mises stress in the first case is 5.5 MPa, while in the second case it's only 1.8 MPa.
