ABSTRACT
Objective
Perioperative deep prosthetic joint infection (PJI) is a serious postoperative complication of total hip arthroplasty (THA). We aimed to compare the efficacy of cefazolin administered within 24 and 48 h of primary THA for PJI prophylaxis.
Methods
In this retrospective study, 720 patients were divided into two groups depending on whether cefazolin was administered as a single injection of 2 g twice daily within 24 (24-h group) or 48 h of surgery and the following day (48-h group). Sex, age at surgery, body mass index, co-existing diseases, blood test data, and PJI risk factors were evaluated.
Results
The 24- and 48-h groups included 364 and 356 patients, respectively. Diabetes mellitus was the most common risk factor for PJI in both groups. The corresponding incidence of perioperative deep PJI following primary THA was 0.55% and 0.28% in the 24- and 48-h groups, respectively. There was no significant difference in patient background characteristics between the groups.
Conclusions
Cefazolin administration within 24 h of primary THA may be appropriate for perioperative deep PJI. Level of Evidence II; Retrospective study.
