In this study, the design and simulation of knee prosthesis was investigated. The presented model included femur bone, tibial head, meniscus, muscle, socket, and liner, which was first subjected to physiological loading, and based on the results, the optimization process was performed on the socket. Next, the optimized and non-optimized sockets were subjected to the same loading and the boundary conditions in order to study the effect of the optimized socket on the stress and displacement of different components of the leg prosthesis. The results demonstrated that the optimized socket reduces the equivalent stress based on von Mises throughout the leg, and slightly reduces the displacement. The intended behavior showed the effectiveness of the optimal socket in absorbing stress and protecting other organs and strengthened its use for medical applications in future. The model can be improved by including the dependence of bone material properties on density and analyzing in cyclic loadings and different forces to evaluate the behavior of the presented model in different conditions.
