A recent international multicenter study involving 647 patients revealed a high discordance rate of 36% between preoperative and intraoperative cultures in revision arthroplasties for periprosthetic joint infections. Conducted across 16 hospitals from January 2020 to January 2024, the study identified factors such as the type of arthroplasty and the presence of sinus tracts contributing to this discordance. The lead author, Dr. Karsten D. Ottink, emphasized the importance of understanding these discordance rates to enhance perioperative management and antibiotic selection, ultimately improving patient outcomes.
