start to treat as septic knee with aspiration asap.
Clinical approach to evaluation and management of suspected septic arthritis

* Add aminoglycoside if Pseudomonas is suspected.
¶ The clinical approach in the setting of a positive Gram stain and negative culture depends on individual circumstances. It is advisable to seek consultation with an infectious disease specialist if possible, repeat cultures if applicable, and assess the evidence for the presence of an alternate diagnosis (such as crystal-induced arthritis).
