Total hip arthroplasty (THA) has been in use with reasonable and increasing success for over 40 years. However, the conventional, long-stemmed, Charnley (1960) implant alters the natural loading in the proximal femur from bending and axial load to more of a shear and circumferential load. This change in load often causes the bone to remodel, which can eventually lead to loosening of the implant. This problem is particularly common among younger, more active THA recipients. Therefore, patients under age 60, who could benefit from THA may be encouraged to postpone surgery to reduce the potential need for future revision surgeries caused by loosened prostheses. The authors’ overall goal in this work was to design and test a new prosthesis that reduces this stress redistribution using a rigorous engineering approach.
