Hip resurfacing has in recent years become increasingly popular as an arthroplasty technique, particularly amongst younger patients with more active lifestyles. The procedure has been heralded as a more conservative option, aimed at those wishing to continue strenuous work and recreational activities. Little evidence has appeared in the literature however, either with the results of resurfacing or comparing resurfacing to conventional total hip arthroplasty.

We compare the outcomes of a consecutive series of hybrid hip resurfacings against a similar series of conventional hybrid hip arthroplasties. In our series there was no difference in operation time, blood loss, or modified Harris Hip score at 12 months postoperatively. There was a small decrease in length of stay, which was not clinically significant. We conclude that whilst it has been previously shown that there is an overall preservation of bone stock following resurfacing arthroplasty, there is no evidence to back additional claimed benefits.
