TL;DR: Surgeons must consider implant design, expected component size and acetabular component positioning in order to reduce early failures when performing large-bearing metal-on-metal hip resurfacing and replacement.

TL;DR: Increased wear from the metal-on-metal bearing surface was associated with an increased rate of failure secondary to ARMD, however, the extent of tissue destruction at revision surgery did not appear to be dose-related to the volumetric wear.

TL;DR: Wear at the modular junction is an important factor in the development of adverse tissue reactions after implantation of a large-diameter MoM THR, and co-ordinate measuring machine analysis of revised components showed that all patients suffering adverse tissue reacting in the resurfacing group had abnormal wear of the bearing surfaces.

TL;DR: Accurate positioning of the acetabular component intra-operatively is essential in order to reduce the concentration of metal ions in the blood after hip resurfacing arthroplasty with the Articular Surface Replacement implant.

TL;DR: The analysis of the first consecutive 126 failed mated total hip prostheses from a single manufacturer suggests that varus stems, laterally engaging taper systems and larger head diameters all contribute to taper failure.
