Chemical debridement is a fundamental step during Periprosthetic joint infection (PJI) surgery. Antiseptic solutions are commonly used, but evidence on the optimal antiseptic, concentration, and irrigation time is lacking. The aim of this study is to analyze and compare the anti-biofilm capacity of povidone iodine, H202, acetic acid and Bactisure™ after different exposure times, as well as their combinations. Surgical steel discs inoculated with methicillin susceptible (MSSA) and resistant Aim
Method
Two-stage replacement is a frequent procedure in patients with chronic PJI. However, results in the literature after this procedure differ, ranging from 54% to 100% of infection eradication. Positive cultures at reimplantation, when performing the second stage, are perceived as a risk factor for reinfection. This study aims to determine the impact of positive cultures during the second stage on the outcome of patients undergoing a 2-stage septic replacement and the impact of antibiotic holidays between the first and the second stage. We systematically searched four databases from inception to May 31, 2022. We combined terms related to PJI, joint replacement and culture results. We analysed the risk of failure when positive cultures at second stage and performed a subgroup analysis by antibiotic holiday period.Aim
