Which method demonstrates the intercondylar fossa while placing the patient in an anteroposterior (AP) axial projection?

The Béclère method is specifically designed to visualize the intercondylar fossa in an anteroposterior (AP) axial projection. This technique involves positioning the patient supine with the knee flexed at an angle of approximately 40 to 45 degrees. The central ray is directed perpendicular to the long axis of the tibia and entering at the level of the popliteal fossa. This positioning allows for optimal visualization of the intercondylar fossa, which is the area of interest between the femoral condyles.

In contrast, other methods mentioned serve different purposes or angles for imaging. The Settegast method typically offers a view for the patella in a different projection configuration. The Camp method also aims to demonstrate the intercondylar fossa but is performed with the patient in a prone position, which changes the angle and potential visualization of the fossa compared to the Béclère method. The Merchant method is primarily utilized to visualize the patellofemoral joint rather than focusing on the intercondylar fossa specifically.
