a
Summary of the culture yield of patients with a suspected prosthetic joint infection (PJI) prior to surgery who underwent revision surgery with or without preoperative antimicrobial prophylaxis (20, 24).
b
Patients with a (presumed) aseptic loosening or chronic pain who underwent a total, partial, or minor revision surgery.
c
Patients who met one or more of the minor or major diagnostic criteria as defined by the Musculoskeletal Infection Society (26). From the data for this cohort, patients that were treated with debridement or antibiotics and with retention of the prosthesis in this study (14 out of 28) were excluded from the analysis.
