“Considering Conservative Management for Hip Joint Effusion in Children with Normal Inflammatory Markers and Effusion Volume < 0.5 cc"

https://pubmed.ncbi.nlm.nih.gov/38115094

The study suggests that in children with hip joint effusion and normal inflammatory markers (CRP and ESR) and effusion volume less than 0.5 cc, conservative management and close follow-up may be recommended instead of joint fluid aspiration for diagnosing septic arthritis.
