Mid-Course Infection Risk Reduction Grade: A-?

According to the American Academy of Orthopaedic Surgeons (AAOS), infection rates after total hip arthroplasty and total knee arthroplasty range between 0.5% and 2%.

While this is a low percentage, because the number of total joint replacement surgeries performed continue to increase every year in the U.S., infection risk and the human and financial costs of treating surgical site infections is still a major concern.
