What is the correct patient position for an AP axial Beclare method projection of the intercondylar fossa?

• A. Lying supine
• B. Prone
• C. Standing
• D. Seated

Answer: (A)

For the AP axial Beclere method, the knee is placed in a supine position with the knee flexed about 40 degrees. The central ray is directed cephalad at roughly 40 degrees, entering just distal to the patellar surface and exiting through the intercondylar fossa. This setup aligns the beam to project the intercondylar fossa in profile and minimizes superimposition of the femoral condyles, giving a clear view of the fossa. Using a supine position keeps the leg stable and allows the precise knee flexion and beam angle needed; other positions would alter limb alignment and prevent the correct angle, reducing the view of the intercondylar area.
