Minimally invasive arthroscopy of the knee using a new 2 mm device.

Arthroscopy has been evolving over the last decades, whereas arthroscopic devices have not changed much. Smaller diameter arthroscopes would potentially reduce the intraoperative trauma for cartilage and soft tissues. Two-millimeter-diameter arthroscopy demonstrated very good visualization and reach of intraarticular structures-similar to knee arthroscopy using a standard arthroscopic system.
