Dr. Incavo and colleagues recently received The Knee Society’s 2021 Chitranjan S. Ranawat, MD Award for their research, Intraosseous Vancomycin Reduces Periprosthetic Joint Infection in Primary Total Knee Arthroplasty at 90-Day Follow-Up. Published recently in the Bone & Joint Journal, the work is a retrospective review of a consecutive series of primary TKAs, examining incidence of periprosthetic joint infection (PJI), adverse reactions, and complications using IV versus intraosseous (IO) vancomycin at 30-day, 90-day, and one-year follow-up.
