To evaluate the outcomes of patients undergoing two-stage revision for hip and knee PJIs with at least one positive culture at reimplantation and identify associated risk factors.
Key Findings:
15-30% of cases show persistent positive cultures at reimplantation.
Certain pathogens linked to higher failure and mortality rates.
Patient-related factors such as older age and higher ASA scores correlate with poorer outcomes.
Interpretation:
Positive cultures at reimplantation may indicate a higher risk of infection recurrence and re-revision, necessitating a tailored approach to patient management.
Limitations:
Retrospective design may introduce bias.
Limited generalizability due to single-center study.
Potential for incomplete data in medical records.
Conclusion:
Understanding the implications of positive cultures at reimplantation is crucial for improving patient outcomes in two-stage revision surgeries.
