drawer sign

drawer sign [AS, dragan, to drag] , a diagnostic sign of a ruptured or torn anterior cruciate or posterior cruciate ligament of the knee. Testing involves having the patient flex the knee at a right angle while the lower leg is grasped just below the knee and moved first toward, then away from the examiner. The test result is positive for the knee injury if the head of the tibia can be moved more than a half inch from the joint. See also anterior drawer sign or test.
