Summary
Differentiating between septic arthritis and other causes of joint inflammation in pediatric patients is challenging and of the utmost importance because septic arthritis requires surgical debridement as part of the treatment regimen. 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.

This will be performed by CD Diagnostics if any organisms are present in the synovial fluid.
These test strips will be tested at the hospital where the patient is being seen, a few drops of synovial fluid will be used on the strip.
In participants \< 8 years old, a sample of synovial fluid will be tested for Kingella kingae using PCR.
