Alternate AP knee method assures open joint space.
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.
