This was a retrospective cohort study, with a follow-up of at least 2 years or until the patient died. Prosthetic joint-associated infection was defined according to Crockarell et al. (1998) , and required 1 or more of the following criteria:
(I) growth of the same microorganism in at least 2 culture specimens (preoperative joint aspiration and/or intraoperative, intracapsular specimen); (II) 1 positive culture, and intracapsular purulence during debridement procedure, acute inflammation on histopathological examination of intraoperative specimen, and/or an actively draining sinus tract; (III) culture-negative infection: negative culture results and at least 2 of intracapsular purulence during debridement procedure, acute inflammation on histopathological examination of intraoperative specimen, and an actively draining sinus tract.
The study population consisted of 91 patients who were treated with DAIR for PJI of total hip arthroplasty (THA) or total knee arthroplasty (TKA) at 3 Dutch hospitals between January 2004 and December 2009. 34 of the patients with PJI of the hip have already been described (Kuiper et al. 2013 (link)) and they were also included.
