Outcome and Failure Analysis of 132 Episodes of Hematogenous Periprosthetic Joint Infections-A Cohort Study.

Persistence-/relapse-free survival after treatment of hematogenous PJI was high (84%). New hematogenous PJI due to the same or a new pathogen occurred frequently, reducing treatment success to 62% after 4 years of follow-up, suggesting an individual predisposition to hematogenous PJI. The outcome was similar for different pathogens but worse in episodes treated with prosthesis retention compared with multistage exchange.
