Abstract
The present disclosure relates to orthopedic implants including a porous, non-metallic, bone interface or outer bone contacting surface adapted for promoting bone ingrowth into the pores of such surface. The present disclosure also relates to orthopedic implants having a porous, non-metallic and/or polymeric bone interface or outer bone contacting surface wherein the implant has a stiffness that approaches or substantially matches the stiffness of the surrounding bone and thereby reduces the effects of stress shielding. The present disclosure also relates to methods of making such implants.
