Computed tomography of the knee with reference to meniscal tears. A preliminary report.

CT scanning of the knee was performed in one patient with a Baker's cyst and normal menisci and 8 patients with meniscal tears diagnosed at arthrography and confirmed at arthrotomy. The normal menisci were clearly demonstrated. The torn parts of the menisci invariably had ill-defined free edges and contained areas of low CT attenuation. In 2 patients swelling peripheral to the torn meniscus was only demonstrated at CT.
