Abstract

The production and release of wear particles from materials remains an unresolved challenge in total hip replacement. Alternatives to the usual articular couplings have been proposed over the past few years in an effort to limit the release of polyethylene particles from the head. Ceramic-on-ceramic articulating prostheses have been the most successful, since a ceramic device when properly formed and expertly implanted shows a significantly reduced wear rate compared with polyethylene-although it implies a higher cost. Metal-on-metal prostheses recently have been reconsidered due to the fabrication of new metal alloys with high-wear resistance. The follow-up data on metal-on-metal as well as on ceramic-on-ceramic prostheses cover a shorter time than the available results from metal-on-polyethylene combinations. Although final conclusions cannot be drawn, current research and practice are valuable for total hip replacement design for the future.
