Risk Factors for Discordance Between Synovial Fluid Culture and Intraoperative Cultures in Revision Arthroplasties: Results From a European Multicentre Observational Study.

Key Points

• This research examines the factors contributing to discrepancies between synovial fluid cultures and intraoperative cultures in revision arthroplasties.
• Multicenter observational study design
• Examined preoperative synovial fluid cultures and intraoperative cultures
• Focused on cases of hip arthroplasties and presence of sinus tracts
• High rate of discordance observed, particularly in hip arthroplasties
• Discordance varies significantly across different centers
• Intraoperative cultures are less reliable when sinus tracts are present
