Final answer:
A patellar view should capture the femoropatellar joint, which includes the patella and the distal femur. Additionally, the quadriceps tendon and patellar ligament should be visible, as they are significant in knee stability and leg extension movements.
Step-by-step explanation:
When taking a patellar view radiographically, it is important to capture the correct anatomical structures. The femoropatellar joint should be included, which is the joint space between the patella and the distal end of the femur. Since the patella is a sesamoid bone located within the tendon of the quadriceps femoris muscle, this muscle and its association with the knee joint's dynamics should also be recognized. The quadriceps tendon, along with the patellar ligament which extends from the patella to the anterior tibia, are key structures that facilitate leg extension at the knee joint and also provide support and stabilization to the knee.
