An evaluation of information available on the internet regarding minimally invasive hip arthroplasty.

The Internet is a popular source of information regarding health care especially when seeking advice on new and less invasive surgical techniques. We evaluated 150 Web sites (3 search engines) for authorship and quality of information regarding minimally invasive hip arthroplasty. The results revealed that 45% were authored by a hospital/university, 26% were news stories, 25% were private medical groups, and 6% were orthopedic industry Web sites. Forty-five percent offered the opportunity to make an appointment, 41% described the surgical technique, and only 15% explained eligibility. Thirteen percent described the risks, whereas 9% made reference to peer-reviewed publications. More than 91% made specific claims regarding the advantages of minimally invasive surgery. Our study suggests the information on the Internet regarding minimally invasive total hip arthroplasty is misleading and of poor quality.
