title: Alternate AP knee method assures open joint space.
abstract: 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.
