The Quality of Web-Based Information on Hip Resurfacing Arthroplasty: A Cross-Sectional Survey

The Internet has become an important source of information for patients. Websites offering medical information are not subject to peer-review. The aim of this study was to evaluate the quality of information available on the web regarding hip resurfacing arthroplasty. The search term ‘hip resurfacing’ was entered into five commonly used general search engines. The 20 highest-ranked websites from each engine were reviewed, after eliminating duplicate and non-relevant sites. Each site was then given a quality score (maximum of 20) according to predefined general and specific criteria. Our search identified 40 unique websites. Commercial websites were the most common (n=17). Quality scores ranged from 8 to 18, indicating that the quality of information on the web varied widely. The mean score for all sites was 11.7, SD 2.6, and only four websites scored >15. Fifteen sites did not mention the disadvantages or complications specific to hip resurfacing. The quality of information on the Internet regarding hip resurfacing is variable. Only four sites out of 40 were deemed to be of high quality. Orthopaedic surgeons need to be aware of these limitations, and take the lead in educating and counselling their patients.
