The current gold standard to diagnose septic arthritis in children is a positive synovial fluid culture; however, joint cultures may take several days to return. If a bacterial infection is present, it requires immediate surgical intervention in order to prevent lasting articular cartilage damage. Frequently surgeons must decide whether to surgically debride a joint before culture results are available. There is no single lab test or clinical feature that reliably indicates bacterial infection over other causes of joint inflammation. The alpha-defensin assay has shown high sensitivity and specificity for joint infection in other studies.The purpose of this study is to determine the sensitivity and specificity of several synovial biomarkers for diagnosing pediatric septic arthritis.",[25,26,27,28],"Joint Infection","Infection of Hip Joint (Disorder)","Infection of Shoulder Joint","Septic Arthritis",[30,31,32,33],"synovial biomarkers","alpha-defensin","diagnostics","pediatric","RECRUITING","2025-06-17",{"date":37,"type":38},"2025-06-22","ACTUAL",{"date":40,"type":38},"2016-06-28",{"date":42,"type":19},"2026-05",{"name":44,"class":45},"Hospital for Special Surgery, New York","OTHER",3]
