Abstract: Based upon previous research on the relation between hip prosthesis designs and strain distributions in a proximal femur model, a prototype of a “physiological” hip prosthesis was designed and manufactured. Strain gauge measurements on a dry femur before and after implantation of this prosthesis were made in different loading conditions simulating one-legged stance with and without torsional loading and two-legged stance. The strains in the outer cortex were within 10% of the physiological values along the whole medial side in all measurement conditions.
