Hip resurfacing is a bone-conserving alternative to total hip replacement for the young and active adult with end-stage hip disease. Determinants of health including gender and socioeconomic status have been demonstrated to impact outcomes in total hip arthroplasty but little is known of their effect on patient outcomes in hip resurfacing. The aim of this study was to investigate whether there are differences in post-operative functional outcomes, and rates post-operative complications and revisions for patients of different gender and socioeconomic status receiving a hip resurfacing arthroplasty.

Between November 2004 and December 2008, 204 consecutive hip resurfacings were performed in 187 patients by a single surgeon in a high-volume academic hospital. The impact of patient gender and socioeconomic status was analyzed with respect to post-operative functional outcome scores and complication and revision rates.

There were no significant differences between males and females with respect to functional outcomes or rates of complication or revision. Socioeconomic status was not significantly correlated with complication or revision rate. Of the patients residing in Toronto receiving a hip resurfacing, 54% lived in neighbourhoods of highest socioeconomic status while only 14% lived in neighbourhoods of low socioeconomic status.

The current work did not demonstrate a correlation between patient gender nor socioeconomic status and outcomes following hip resurfacing arthroplasty in this single surgeon series. Toronto residents receiving a hip resurfacing tended to reside in neighbourhoods of higher household income and thus this study demonstrates a propensity for individuals of higher socioeconomic status to receive a hip resurfacing arthroplasty.
