✦ Synopsis

A numerical optimization technique was used to improve the design of a coated, cementless hii3 prosthesis. The prosthesis was represented by a simple one-dimensional finite element model, and its diameter and coating thickness at various points were altered so as to minimize stress shielding while keeping implant bone interface stresses within realistic limits. The resulting design showed a very large reduction in both stress shielding and interface stresses compared to conventional designs.
