This video outlines the posterior drawer test/sign for PCL pathology. With the patient lying supine, the hip bent at 45 degrees and the knee bent at 90 degrees, the examiner sits on the patients foot to stabilize the limb. Then, with the palms placed on either side of the proximal tibia, a posterior force is applied. Excessive laxity (especially if more than the opposite limb) is a sign of possible PCL injury.
