[A simple method of studying cruciate ligaments in arthrography]

After a review of the methods employed for arthrographic visualization of cruciate ligaments (CL), the authors present a new technique to separately study the anterior and posterior CL during traction. This technique enables to obtain a good visualization of CL and a good diagnostic accuracy; it can radiographically demonstrate a pathologic sagittal instability of the knee; it is easy to perform and is easily repeatable in different patients.
