In obtaining an axial view of the patella, what positioning is required?

To obtain an axial view of the patella, positioning is crucial for the optimal visualization of the knee joint and patellar anatomy. The correct choice involves placing the patient in a prone position with the knee fully flexed. This specific positioning helps to place the patella in a more perpendicular orientation to the imaging receptor, allowing for a clearer view without interference from surrounding structures.

When the patient is prone and the knee is fully flexed, the patella is brought out from its natural position along the femur, reducing overlapping of the femoral condyles and providing a direct line of sight for radiographic imaging. This technique increases the accuracy and detail of the image captured.

Additionally, this positioning allows for better visualization of possible patellar pathologies or abnormalities, as well as an understanding of how the patella interacts with the femur during knee motion. Proper alignment of the knee in this position is essential to highlight any potential issues such as patellar displacement or degenerative changes.
