Arthroscopy is a surgical procedure by which the internal structure of a joint is examined and treated accordingly.

The procedure is done with a small incision on the skin through which p a small lens and lighting system (arthroscope) are passed. 

This Arthroscope magnifies and illuminates the structures of the joint with the light that is transmitted through fiber optics. To visualize this, a 4K television is connected via the arthroscope and recording can also be done for documentation.
