An arthroscope is the main instrument used for looking into the knee during keyhole surgery - ie arthroscopy.

Components of the arthroscope
Light is shone into the knee through the arthroscope, which has a small lens at the far end to angle the light beam. Fibre-optics relay the view to a monitor which is usually mounted at the surgeon's eye level behind the operating table.
