Which statement about lateral patella radiography is true?

• A. The image receptor must be placed in the bucky tray.
• B. Leg is rotated 45 degrees to the affected side.
• C. Technique is reduced to prevent overexposing.
• D. Inferior-superior axial position is most frequently used.

Answer: (C)

In lateral patella radiography, controlling exposure to preserve bone detail is essential. The patella is a small, dense bone, and in this view the beam passes through mostly bone with limited soft-tissue attenuation, so using standard knee exposure settings can easily overexpose the image and wash out fine details. Reducing technique helps maintain appropriate receptor exposure, ensuring you can see the patella, its margins, and any fracture lines or patellofemoral joint details clearly. The position should be a true lateral with the knee flexed to place the patella in profile, rather than rotated; tangential inferior–superior views are separate projections used for different assessments, and while image receptor placement can vary by technique, optimizing exposure is the key factor here.
