Which procedure allows one to view inside a joint?

Arthroscopy is a minimally invasive surgical procedure that enables a physician to visualize the interior of a joint using an arthroscope, a small camera attached to a tube. This procedure is particularly useful for diagnosing and treating various joint conditions, as it allows the physician to examine the cartilage, ligaments, and other important structures within the joint directly.

Unlike imaging techniques such as CT scans, MRIs, and X-rays, which provide images of the joint from the outside or through imaging techniques, arthroscopy involves inserting the camera directly into the joint, providing a real-time view and the ability to conduct minor surgical interventions if necessary. This capability is essential in both the diagnosis and treatment of joint problems, making it a unique and valuable procedure in orthopedic medicine.
