Effect of femoral mechanical properties on primary stability of cementless total hip arthroplasty: a finite element analysis

With the goal of increasing the survivorship of the prosthesis and anticipating primary stability problems of new prosthetic implants, finite element evaluation of the micromotion, at an early stage of the development, is mandatory. This allows assessing and optimizing different designs without manufacturing prostheses. This study aimed at investigating, using FEA, the difference in the prediction of the primary stability of cementless hip prostheses implanted into a Sawbones
