title: Assessment of Quality and Content of Online Information About Hip Arthroscopy.
abstract: The purpose of this study was to assess the quality of information available to patients on the Internet when using popular search engines to search the term "hip arthroscopy."
  
  
  
  We analyzed the quality and content of information about hip arthroscopy (HA) on the first 50 websites returned by the search engines Google and Bing for the search term "hip arthroscopy." The sites were categorized by type, and quality and content were measured using the DISCERN score, along with an HA-specific content score. The HA-specific content score was used to assess each website for the presence or absence of 19 topics about HA determined to be important for a patient seeking information about the procedure. The Health on the Net Code (HONcode) status of each website was also noted.
  
  
  
  The mean DISCERN score for all websites analyzed was 39.5, considered "poor," while only 44.6% of sites were considered "fair" or "good." Governmental and nonprofit organization (NPO) websites had the highest average DISCERN score. The mean HA-specific content score was 8.6 (range, 2 to 16). The commercial website category had the highest average HA-specific content score, followed by the governmental and NPO category. Sites that bore the HONcode certification obtained significantly higher DISCERN scores than those without the certification (P = .0032) but did not obtain significantly higher HA-specific content scores.
  
  
  
  "Hip arthroscopy" is a fairly general term, and there is significant variability in the quality of HA information available online. The HONcode is useful to identify quality patient information websites; however, it is not commonly used in HA-specific websites and does not encompass all quality websites about HA.
  
  
  
  This study increases awareness of the quality of information on HA available online.
