     the use of an artificial joint is always related to a certain amount of wear. its biological effects, e.g., the osteolysis potential, are a function of the bulk material as well as its debris. following comprehensive experiences with polyethylene (pe) wear, material science is tracking two ways to minimize the risk of a particle-induced aseptic implant loosening: (i) reduction of the pe debris by a low-wearing articulation partner; and (ii) replacement of the pe by other materials. therefore, new ceramics (e.g., zta, si3n4), as well as coatings (e.g., tin, “diamond-like” carbon) and modifications of a bulk metal (e.g., oxidizes zirconium) or cushion bearings (polyurethane, hydrogels), are currently available for total joint replacements or have been used for pre-clinical testing. this review gives a brief overview and evaluates the potential of those that have recently been published in literature.
