Serum and Synovial Biomarkers for Distinguishing Between Chronic Periprosthetic Joint Infections and Rheumatoid Arthritis: A Prospective Cohort Study

Inflammatory responses in patients with active rheumatoid arthritis (RA) may lead to the current serum and synovial fluid biomarkers that misidentify chronic periprosthetic joint infection (PJI). We sought to investigate the expression of serum and synovial biomarkers in patients with active RA and to calculate thresholds for valuable biomarkers that distinguish between chronic PJI and active RA.This prospective study was initiated to enroll 70...
