What is the main advantage of using arthroscopy over arthrography?

The main advantage of using arthroscopy over arthrography is that arthroscopy provides a more detailed visualization of joint structures. During arthroscopy, a small camera is inserted into the joint through a small incision, allowing for direct visualization of the internal structures. This technique enables the healthcare provider to see and assess the condition of the cartilage, ligaments, and other joint components in real time, as well as to perform diagnostic and sometimes therapeutic interventions.

In contrast, arthrography is a radiographic technique that involves injecting a contrast dye into the joint and then taking X-rays to visualize joint structures. While it can provide useful images, the detail and clarity of the visualization are limited compared to what can be observed during an arthroscopic procedure. Thus, if the goal is to have the most comprehensive view and assessment of joint pathology, arthroscopy is the superior choice.
