Abstract
We examined three new interfaces for porous ingrowth hip surface replacements using linear and nonlinear contact finite element analysis. The results indicate that a flatter interface than is usually used, similar to the epiphyseal line, may improve surface replacement longevity. In addition we find that linear analysis of the pressure at the prosthesis-bone interface gives significantly different results than does an analysis which models the interface as a slip surface. This means that the stress patterns at the interface immediately post-implantation, before bony ingrowth occurs, can not be accurately determined from a simple linear analysis.
