Clinical Characteristics Etiology and Initial Management Strategy of Newly Diagnosed Periprosthetic Joint Infection: A Multicenter Prospective Observational Cohort Study of 783 Patients

摘要

Periprosthetic joint infection (PJI) is a devastating complication of joint replacement surgery. Most observational studies of PJI are retrospective or single-center, and reported management approaches and outcomes vary widely. We hypothesized that there would be substantial heterogeneity in PJI management and that most PJIs would present as late acute infections occurring as a consequence of bloodstream infections.
