About

This is a multicenter prospective cohort study in which patients were evaluated by inclusion and exclusion criteria before phase II revision surgery. Eligible patients will be included in this study after signing the informed consent form. After the second stage revision, according to the patient's symptoms and examination results, the attending physician used a reasonable antibiotic treatment scheme (including intravenous and oral medication). All patients voluntarily participated in the study and signed informed consent. During the treatment period, all prospective patients underwent clinical evaluation at the time points of 1, 3, 6, 12, 18 and 24 months after the start of antibiotic treatment after phase II revision. The infection control rate of patients was evaluated by follow-up at least 2 years after operation, so as to analyze the effect of antibiotic treatment course after two-stage revision of periprosthetic joint infection.
