Double contrast arthrographic evaluation of the anterior cruciate ligament.

A review of 100 surgically confirmed cases indicates that double contrast arthrography, performed and interpreted with the described criteria, can accurately demonstrate the status of the anterior cruciate ligament. Visualization of the posterior cruciate ligament, which is less commonly injured, assures that proper radiologic positioning has been attained. Joint distraction is used to increase the visualized length of the anterior cruciate ligament coated by contrast agent. Various types of anterior cruciate ligament abnormalities as well as the high incidence of anterior cruciate ligament in young athletes are emphasized.
