Abstract Background Managing periprosthetic joint infections are variable in practices. Debridement, antibiotics, and implant retention (DAIR) is one of the favorable interventions. Given that success rate two-stage revision total knee arthroplasty (rTKA) might be overestimated. The purpose this study to compare between DAIR standard rTKA with a comparable intervention time. Methods We retrospectively reviewed consecutive infection cases which underwent or (all procedures were performed by senior author) within 12 weeks since their primary TKA July 2009 October 2019. Average follow-up was 72.20 ± 40.70 months (range 29–148 months) group compared 89.14 43.06 after spacer insertion 29–163 ( P = 0.156). According different interventions, demographic data; timing surgical intervention; hospital for special surgery score; collected group. Failure treatment based on Delphi consensus fate spacers. pathogen types failure also recorded analyzed. Results Time from index 3.90 2.92 0–12 weeks) group, 5.11 2.86 2-stage exchange respectively. 70.0% 75.0% But no significant differences observed two groups. Conclusion demonstrated effectiveness rTKA. recommended as choice patients current TKA. For methicillin-resistant staphylococcal fungal infections, preferred.
