In acute monoarticular arthritis with low gout probability, when perform joint aspiration?

Acute monoarticular arthritis requires timely distinction between gout and septic arthritis. In patients presenting with a single swollen joint, the core decision is whether to perform joint aspiration, particularly when the pretest probability of gout is low. While synovial fluid analysis is highly specific for monosodium urate crystals and essential to exclude septic arthritis, a negative result does not reliably rule out gout in low-probability cases. This creates diagnostic uncertainty and potential risk if results are overinterpreted. The discussion outlines a default strategy of aspiration when gout is suspected, with urgent aspiration and empiric therapy in high-risk or immunocompromised patients. It also addresses when adjunctive evaluation, repeat aspiration, or close follow-up is warranted, emphasizing clinical context over isolated laboratory values. Clinical decisions should prioritize exclusion of septic arthritis while avoiding false reassurance from negative synovial fluid results. #Gout #SepticArthritis #Rheumatology #InternalMedicine #ClinicalDecisionMaking
