Infection Prevention in Total Knee Arthroplasty

Brian K. Daines, MD, J Am Acad Orthop Surg June 2015 ; 23

Periprosthetic joint infections are devastating complications that are difficult and expensive to treat and have a substantial mortality rate. A major goal of modern joint arthroplasty is to minimize these infections. Preoperative factors associated with increased risk of infection include malnutrition, diabetes mellitus, obesity (body mass index >40 kg/m2), and rheumatoid arthritis. Administration of appropriate antibiotics before the surgical incision is made is essential to minimize infection. The use of laminar flow rooms, proper skin preparation, limiting operating room traffic, and the use of various wound closure techniques can help to decrease infection rates. Postoperatively, optimal management of indwelling urinary catheters, blood transfusions, and wound drainage also may decrease infection rates
