Final answer:
Arthrography is the best method of radiologic imaging to view the internal structures of the knee.
Step-by-step explanation:
The best method of radiologic imaging to view the internal structures of the knee is arthrography. Arthrography uses a contrast agent, such as a dye, that is opaque to X-rays, allowing the soft tissue structures of the knee joint, such as cartilage, tendons, and ligaments, to be visualized. An arthrogram can detect early degenerative changes in joint cartilage before it affects the bones.
