A single-center retrospective cohort study was conducted in the Department of Orthopedics, the First Affiliated Hospital of Fujian Medical University. This study reviewed 145 patients who underwent debridement, antibiotics, and implant retention (DAIR), 1-stage revision, 1.5-stage revision, and 2-stage revision surgeries for total knee arthroplasty periprosthetic joint infection (TKA-PJI) at this institution between 2012 and 2022. The differences in postoperative reinfection rate, microbial composition of reinfection, short-term and long-term aseptic prosthesis survival rate, prosthesis loosening and revision rate due to any cause, and long-term loosening-free survival rate among the four revision surgical approaches for TKA-PJI were evaluated, so as to provide reference value for clinical decision-making.
