“…A comprehensive search identified 4 published studies reporting the clinical outcomes of 253 hip resurfacing procedures in patients aged 30 or less at the time of surgery (3336). The largest series is 156 resurfacings from the Birmingham group, who reported 10% revision at 5 years follow-up (33), compared with 5% revision at 8.4 years in our meta-analysis.…”

“…MoM bearings have been further developed for surface replacement in order to preserve bone on the femoral side5, 6 and for larger head sizes to achieve enhanced range of motion and stability 7, 8. These designs were often targeted at younger, more active patients 9, 10. However, adverse conditions such as implant malpositioning can lead to edge loading or head‐cup rim contact, and produce high contact stress causing elevated wear 11.…”

“…It is important to remember that MoM is currently the only bearing technology that allows to perform hip resurfacing while preserving bone on both the femoral and the acetabular sides because it is the only material providing sufficient strength to manufacture thin monoblock acetabular components with a reliable cementless fixation. Hip resurfacing has already shown excellent results in multiple studies at 10 years in patients with large components and good bone quality (32-33-34) and very favourable result in a variety of other conditions (35-36-37-38). Although the differences in serum metal ion concentrations observed in this study are small in magnitude and the clinical results comparable, the use of a differential hardness bearing may still be considered over the use of a conventional heat-treated CoCr bearing because of the potential reduction in wear shown in vitro for this technology and there are no negatives to using the forged femoral component.…”
