Benefits and Adverse Events Associated With Extended Antibiotic Use for One Year Following Periprosthetic Joint Infection in Total Knee Arthroplasty: A Prospective Cohort Analysis.

Background: Periprosthetic joint infections (PJIs) are common and serious complications following knee and hip arthroplasty. Our previous retrospective study suggested extended antibiotics following debridement, antibiotics, and implant retention (DAIR) decreased failure rates and were not associated with increased adverse events (AEs) as compared to a standard 6 weeks of antibiotic therapy. Further, extended antibiotics beyond one year did not provide additional benefits.

Postoperative infection and bone sarcoma survival: systematic review of the role of infection in bone sarcoma prognosis.

Background: Osteosarcoma (OS) and chondrosarcoma (CS) are primary bone malignancies whose prognoses have stagnated despite advancements in surgical management, chemotherapy, radiation therapy, and immunotherapy. The role of the immune system in generating anti-cancer physiologic responses is critical to prognosis. Prior studies have explored if immune system activation via infection enhances survival in bone sarcomas without a clear consensus.
