Default ac rheumatic fever?

if a pt already diagnosed to have strept pyogenes pharyngitis( +ve throat swab or ASO titre), presents with joint pain, do we perform arthrocentesis to confirm the cause of arthritis?? or the dx is clinical??

bacause the same pt can have septic arthritis from hematogenous spread??

for the septic arthriris by hematogenous spread , patient must have any history of direct trauma to knee or any joint.... as far as ur question concerned, yes, we must have to do arthrocentesis bcz just positive swab or titer isn't the diagnostic criteria for arthritis.

thx for ur reply, but for septic arthritis by hematogeous spread, pt must have history of any focus of infection like pharyngitis or otitis media, from where infection spreads hematogenously to the joint...( n no hx of direct trauma)

n only for septic arthritis by direct contact, there is hx of trauma to joint...!!!

n yes i think arthrocentesis is done to rule out septic arthritis...!!!
