Arthrography of the knee joint with amipaque

In a double-blind investigation, 30 knee arthrographies were performed by injection of either Amipaque 290 mg I/ml or Urografin 60% (292 mg I/ml). Both contrast media are well tolerated, and give excellent initial contrast quality, which deteriorates rapidly. This occurs more slowly with Amipaque, which has lower osmolality and causes less joint effusion.
