A guide for guiding the distal end of an arthroscope above the surface of a bone plate is disclosed. The guide is located on top of the bone plate. It has a body with cutouts and/or grooves to guide the arthroscope. Furthermore the arthroscope has a ball shaped slider close to its distal end. This slider is adapted to interface with the guide and allows movement of the distal end of the arthroscope along the cutouts or grooves.
