Debridement, antibiotics and implant retention (DAIR) is recommended for acute postoperative and late acute prosthetic joint infection (PJI). There are two recommend scores to predict its outcome, KLIC and CRIME 80 scores respectively. They have not been widely adopted for decision making. We aim to evaluate them in predicting DAIR failure in our cohort. All patients submitted to DAIR after total hip or knee PJI, between 2010 and 2021, with a minimum one-year follow-up, were retrospectively evaluated. We excluded tumoral total joint replacements. KLIC score was applied to acute PJIs and CRIME 80 to late acute (LA) PJI. LA PJI was defined as the development of acute symptoms occurring ≥ 3 months after implantation. Repeat DAIR was performed as needed. Failure was defined as the need for implant removal, amputation, infection related death and suppressive antibiotic therapy.Aim
