The Roles of MRI, DYNEELAX and Stress X-ray in First-Line Diagnosis of Cruciate Ligament Injury

Each knee was tested under a force 120 Newtons in a posterior to anterior direction to create anterior tibial translation at 20 degrees knee flexion. Side-to-side difference of anterior/posterior tibial translation (mm) was measured from radiographs. Measurement of rotation and translation by DYNEELAX was also recorded.
