An X-ray fluorescence technique was employed to study the clearance rate from the knee joint of an intraarticularly injected stable tracer.

Abstract

An X-ray fluorescence technique was employed to study the clearance rate from the knee joint of an intraarticularly injected stable tracer. Clearance curves, determined in two normal volunteers and in three patients with various articular diseases, were found to be of the monoexponential type in agreement with results obtained by authors employing radioactive tracers. Clearance half-time values in basal conditions were higher in the normal knee joint than in the inflamed knee joint. The effect of a corticosteroid suspension injected into the knee joint was also studied. Preliminary results obtained indicate that the X-ray fluorescence technique can be employed, with some advantages compared with the radiotracer technique, for quantitative determination of spontaneous or pharmacologically induced changes in joint inflammation.
