Which term refers to the visual examination of a joint cavity using fiber optics and live-action photography?

The term that refers to the visual examination of a joint cavity using fiber optics and live-action photography is arthroscopy. This procedure involves the use of an arthroscope, a small camera that is inserted into the joint through a small incision. This allows physicians to observe the interior of the joint in real time, aiding in diagnosis and treatment of various joint conditions.

Arthroscopy is often performed to investigate problems such as cartilage tears, ligament injuries, or signs of joint disease. It is minimally invasive compared to traditional open surgery, which leads to quicker recovery times for patients and less postoperative pain.

In contrast, arthroplasty refers to the surgical reconstruction or replacement of a joint, arthrotomy involves creating an incision to access a joint for direct examination or treatment, and arthrolysis is a procedure to free up or loosen stiff joints. Thus, those terms describe different aspects of joint surgery or treatment rather than the specific act of visual examination using a fiber-optic camera.
