Between 2007 and 2011, researchers reviewed a prospectively collected infection database to identify periprosthetic joint infections that occurred following primary total knee arthroplasty, which required a two-stage revision. Researchers identified 21 patients and matched them to 21 non-infected patients who underwent uncomplicated primary TKA.
According to the study, the patient who had infections had significantly longer hospitalizations, more readmissions and more clinic visits as compared to the second group. The mean annual cost was $116,383 for the infected cohort as compared to $28,249 for the uninfected group.
