The acetabular cartilage plays an important role in hip joint biomechanics and many reports focusing on its geometric morphometry have been made, but few studies have done some sensitivity analysis to figure out the impacts of geometric shape parameters on hip contact stress. This paper aims to elucidate how the length ratio of the rotational ellipsoidal acetabular cartilage surface's major axis to minor one (ALR) affects the contact stress in the hip, via analyzing finite element (FE) models of hip mechanics with varying ALR. By using the reverse engineering technique and surface-fitting algorithms, 11 best-fit rotational ellipsoidal surfaces of the...
