Implementations described herein are directed toward an improved orthopedic arthroscopy system that reduces the number of necessary arthroscopic portals while at the same time improving endoscopic visualization and instrumentation capability within the joint space. Main embodiments of the disclosed system replace the traditional rod endoscope with a rotatable, optical cannula through which instruments can be used to manipulate tissue and perform surgery. By adding the cannula rotation capability, visualization of instrument tool tip can be easily adjusted. The disclosed system would eliminate the need for unnecessary wrist rotation by the surgeon thereby making it easier to coordinate hand position while performing surgical tasks.
