What is an arthroscope?
An arthroscope is an instrument for looking inside a joint. Early arthroscopes had an eyepiece and the surgeon literally looked inside the joint space, but modern ones project an image onto a mounted monitor.
What are the components of an 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 the monitor and an integral camera allows photography. A separate instrument via a separate portal supplies irrigation fluid under pressure to open up the space. Instuments may be passed into the joint via a third portal.
