The AP knee for a sthenic patient requires the central ray to be directed:
5 degrees cephalic to the femorotibial joint
10 degrees cephalic to the femorotibial joint
perpendicular to the femorotibial joint
3-5 degrees caudal to the femorotibial joint
perpendicular to the femorotibial joint
Rationale: The sthenic patient measures between 18-24 cm from the ASIS to the tabletop which elevates the patient's leg, positioning the tibial plateau perpendicular to the image receptor. Therefore, the CR is directed perpendicular through the femorotibial joint.
