Computed tomography of the knee joint: technique of study and normal anatomy.

Computed tomography was employed in 100 cases to examine the knee joint, without the use of intraarticular contrast medium administration. For greater resolution, only one leg of the patient was introduced into the gantry, and the limb being examined was immobilized and flexed at 8-10 degrees. Computed tomography clearly demonstrated all the anatomical structures that are of clinical interest such as menisci, cruciate and collateral ligaments, and articular and paraarticular soft tissues and tendons. The exact knowledge of the anatomy in axial view and in the indispensable sagittal and coronal reconstructions is fundamental in the identification of pathological conditions.
