Implant separation from bone or cement is widely known serious drawback of bone endoprosthetics. It is believed that stress concentrations on the implant surface are responsible for the failure and that implant shape optimization is the right way of the problem solution. An important tool in effective optimization algorithms is the design sensitivity analysis (DSA). The paper presents the finite element formulation of the sensitivity problem. Three-dimensional model of femur with cementless implant is analyzed.
