title: Prone and supine views in double-contrast knee arthrography.
abstract: The addition of supine views to the standard double-contrast (DC) knee arthrogram with the patient prone can be useful (a) to diagnose meniscal tears not seen otherwise, (b) to provide a second look at an equivocal meniscal lesion, and (c) to enhance subject contrast in the presence of residual joint effusion, or when opaque medium has not adequately coated the interior surfaces of a large joint. In a prospective study of 137 patients, 30 meniscal tears were diagnosed, two of which were visible only on the supine films.
