We assessed the OrthoPAT Orthopedic Perioperative Autotransfusion System (Zimmer Inc, Warsaw, Ind) in reducing the need for allogeneic blood in hip or knee arthroplasty. Patients (N = 398) were divided into 5 cohorts: unilateral primary hip (n = 131), unilateral revision hip (n = 38), unilateral primary knee (n = 179), unilateral revision knee (n = 26), and bilateral primary knee (n = 24). Primary or revision hip arthroplasties with no preoperative autologous blood donation, knee arthroplasties with no preoperative autologous blood donation, and unilateral primary hip arthroplasties were 2.7, 2.3, and 2 times less likely (P < .05), respectively, to use allogeneic blood with OrthoPAT. We conclude that OrthoPAT use significantly reduced the risk of receiving allogeneic blood transfusions in defined patient subsets.

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. ⋯ 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.
