This is a prospective, multicenter, randomized controlled study. Patients were evaluated through inclusion and exclusion criteria. Patients who meet the conditions will sign an informed consent form. After DAIR surgery, they will be treated with intravenous antibiotics for 1-2 weeks and then randomly assigned to one of the following two groups: Antibiotic treatment group: All enrolled patients will be treated with antibiotics (fluoroquinolones or linezolid) for 3 months based on the results of microbial culture and drug sensitivity after surgery. Rifampicin combined with antibiotics treatment group: In addition to the above-mentioned antibiotics, all enrolled patients were treated with rifampicin for 3 months after the operation. The infection control rates of the two groups were judged through at least 2-year follow-up after the operation.The study will follow the Consolidated Standards of Reporting Trials (CONSORT) guidelines for reporting parallel group randomised trials. Ethical approval will be obtained from each institution. Written informed consent will be obtained from all participants to ensure their voluntary participation and understanding of the study.
This study aims to evaluate the efficacy and safety of combined rifampicin for antibiotic treatment in patients with PJI after surgical treatment Sex. The research subjects were PJI patients with staphylococcus as the pathogen. After receiving DAIR treatment, they were screened and enrolled according to strict inclusion and exclusion criteria and randomly assigned to the rifampicin combined with antibiotic treatment group or the conventional antibiotic treatment group only. Then, systematic follow-up was conducted on the patients. Regularly assess its safety indicators such as the recurrence rate of infection, inflammatory indicators, prosthesis function recovery and drug side effects. The data will be entered through a unified recording system and patients who do not meet the research design will be excluded according to the predetermined exit criteria. After the follow-up, the data were summarized and analyzed, with a focus on examining the differences in the efficacy and safety of rifampicin combined therapy in controlling PJI infection. Through this study, we hope to clarify the efficacy and safety of rifampicin combined with antibiotics in PJI treatment, thereby providing a reference basis for the optimization of antibiotic regimens for PJI.

In the "rifampicin combined with antibiotic treatment" group, on the basis of conventional antibiotic treatment, rifampicin is taken orally for an additional three months. In the "antibiotic treatment" group, conventional antibiotics alone are used for treatment

RECRUITINGThe clearance rate of infection, calculated by the formula
The number of subjects determined to have cleared the infection/the total number of subjects who completed the follow-up. Infection clearance is defined as the patient's (1) complete eradication of infection, wound healing, no fistula, no drainage, no pain, and no recurrence of the same strain of infection. (2) No reoperation intervention due to infection; (3) No deaths caused by PJI-related diseases such as sepsis and necrotizing fasciitis occurred
Time frame: two years postoperatively
Adverse events related to PJI
Time frame: Two years postoperatively
Postoperative functional score
Time frame: Two years postoperatively
The rate of prosthesis loosening after surgery, the revision rate, and the proportion of prostheses that need to be removed
Time frame: Two years postoperatively
The incidence of antibiotic complications
Time frame: Two years postoperatively
