PurposePeriprosthetic joint infection (PJI) is one of the most dreaded and challenging complications after total joint arthroplasty (TJA). The aim of this study was to evaluate the effect of keeping the dressing without change on the occurrence of PJI in patients undergoing TJA.Methods4877 Patients with a minimum follow-up of 90 days were included to investigate the effect of dressing on the PJI occurring within 3 months of surgery. Patients were divided into two consecutive groups as the intermittent change of traditional dressing (group 1-before 2019) and keeping dressing for 5 days without change (group 2-after 2019). A backward stepwise logistic regression model was used to estimate independent risk factors for PJI.ResultsGroup 1 and group 2 consisted of 4172 and 705 patients, and the numbers of diagnosed PJI cases in the groups were 40 (1.0%) and 10 (1.4%), respectively (p = 0.1). The backward stepwise logistic regression model analysis revealed that keeping the dressing unchanged and removing it after the first week postoperatively was not an independent risk factor for the occurrence of PJI. Older age, diabetes mellitus and coronary artery diseases were independent risk factors for PJI (p < 0.05).ConclusionOur study results present, that intermittent change of conventional dressing is unnecessary, because it does not decrease the risk of PJI after TJA.Level Of EvidenceLevel III Therapeutic.© 2021.
