This retrospective cohort study of 9,245 primary hip and knee arthroplasties (2001–2006) uses multivariate logistic regression on prospectively collected data to identify independent risk factors for periprosthetic joint infection and characterize its incidence, timing, and causative organisms in the modern arthroplasty era.
When consenting patients for total joint arthroplasty, flag morbid obesity, high ASA score, anticipated bilateral surgery, and likely need for allogenic transfusion as compounding infection risks — and counsel that most infections will declare within the first year.
Postoperatively, new-onset atrial fibrillation or MI should heighten wound surveillance, since these complications carry independently elevated PJI odds beyond what the underlying illness alone explains.
