Length patterns of the posterior cruciate ligament (PCL) were measured with magnetic resonance imaging of five normal human knees. All were male right knees. The average age was 25.6 years. The sagittal view showed the PCL clearly as a low signal intensity in T1 weighted imaging. We evaluated the changes in length during knee flexion from 0 to 120 degree (0, 30, 60, 90, 120 degrees). The maximum length of the PCL was at the 60 degree flexion and its minimun length at 0 and 120 degrees. This suggested that 0 degree flexion of the knee joint avoided the hyper tensile stress of the PCL and that it was a suitable position for the treatments of PCL injuries.
