Periprosthetic joint infection is one of the most challenging complications arthroplasty. We identified current risk factors periprosthetic after modern arthroplasty, and determined incidence timing infection. reviewed prospectively collected data from our database on 9245 patients undergoing primary hip or knee arthroplasty between January 2001 April 2006. infections developed in 63 (0.7%). Sixty-five percent within first year index The infecting organism was isolated 57 cases (91%). common organisms were Staphylococcus aureus epidermidis. following independent predictors for infection: higher American Society Anesthesiologists score, morbid obesity, bilateral allogenic transfusion, postoperative atrial fibrillation, myocardial infarction, urinary tract infection, longer hospitalization. This study confirmed some previously implicated new variables that predispose to infection.Level II, prognostic study.
