"Septic arthritis may be definitively established in the setting of positive synovial fluid Gram stain/culture. In patients with purulent synovial fluid (leukocyte count 50,000 - 150,000) but negative synovial fluid cultures, a presumptive diagnosis of septic arthritis can be made."
Acute Calcium Pyrophosphate deposition would typically have a leukocyte count of 15,000 - 30,000 on aspiration.

If the Gram stain is negative but there is suspicion of bacterial arthritis, vancomycin plus either ceftazidime or an aminoglycoside is appropriate.

Was anyone thinking calcium pyrophosphate? Inflammatory joint, patient with RA, no organisms seen on FNA, would be treated with steroids?
