An alternate method of imaging the knee in the AP projection assures diagnostic joint spaces to provide optimal diagnostic information. The degree of angulation is varied from 5 degrees cephalic to 5 degrees caudal and is determined by measuring the patient's anterior superior iliac spine to table-top distance.
Performing lateral radiography of the knee can be challenging for the technologist because of the problem with superimposing the femoral condyles. There is an alternate method of imaging the knee in the lateral position so that the bony structures are projected to better advantage. For this method, the central ray is angled 5 degrees cephalad and the beam is aligned with the long axis of the lower leg.
