The purpose of this study was to understand patients’ perceptions regarding hip resurfacing arthroplasty relative to conventional total hip arthroplasty (THA)…
A total of 139 consecutive patients were given the survey. Fifty-seven patients (41%) were aware of hip resurfacing arthroplasty and completed the survey. Of those who completed the survey, 29 were men and 28 were women. Mean age of these 57 patients was 51 years (range, 17-98 years). The sources of the patients’ knowledge of hip resurfacing arthroplasty prior to evaluation are listed in Table 1. Patient perceptions of the expectations and outcomes of hip resurfacing arthroplasty are presented in Table 2.
This study suggests that a strong patient bias exists for hip resurfacing arthroplasty that is not supported by peer-reviewed literature. This has important implications when looking at clinical series (retrospective cohort series and randomized prospective series) comparing conventional THA and hip resurfacing arthroplasty. A continued effort should be made to emphasize known scientific data when considering the relative risks and benefits of hip resurfacing arthroplasty and conventional THA.
