[Value of adrenaline in opaque arthrography of the knee. Comparative study of 100 cases]

A prospective study evaluated efficacy of adrenaline in image improvement of opaque arthrography of knee. Of the 100 cases assessed, adrenaline was combined with contrast medium in 50%. Quality of images was compared by double reading of couples of images taken at end of examination. Marked improvement was observed in 2 of 3 cases and it is proposed to use adrenaline routinely to prolong quality of initial arthrogram.
