[Established aspects and current knowledge in biomaterials research].
A review of the currently clinically established biomaterials UHMWPE, Al2O3-ceramic, CoCr- and Ti-based alloys and HA-coatings is given on the basis of recognized and new insights. Advantages and disadvantages as well as prospectives (PE-disease, Ti wear, HA-resorption in vivo etc.) are discussed and documented with results from experimental and clinical experience. New surface hardening techniques for Ti-based alloys are mentioned. Experimental results and singular experience from clinical retrieval study of new plastics (PAEK, Triazin-resin) are presented. Composite materials as a basis for a new generation of isoelastic hip prosthesis stems are described at the end of this paper.
