title: Joint fluid after aspiration. A disturbing factor in knee arthrography.
abstract: The amount of fluid in the knee after aspirating any effusion was investigated and averaged 6.8 ml, being independent of the presence of a lesion. Because it causes dilution of the contrast medium, it is suggested that small amounts of a relatively high-concentrated non-ionic contrast agent should be preferred for double-contrast knee arthrography.
