For an accurate AP projection of the knee, it's essential that the femoral epicondyles are parallel to the image receptor (IR) to ensure that the femoral condyles are symmetrical, which is achieved by properly aligning the leg. The intercondylar eminence should be centered within the intercondylar fossa to accurately represent the knee's anatomy. Additionally, the correct positioning will show the fibular head about 0.5 inch (1.25 cm) distal to the tibial plateau, indicating proper alignment of the lower leg structures in relation to the knee.
