Abstract
A position sensing system which allows the arthroscopist to readily determine the location of an arthroscope's tip in relation to the point of entry has been developed. The position sensing apparatus can be employed in conjunction with a graphics module to display the location of the arthroscope in real time and provide perspective views of the instrument's location.
