Devices and instruments for performing complete shoulder replacement using arthroscopic techniques. The devices may include (i) an arthroscopic camera cannula inclusive of expandable flanges, (ii) arthroscopic camera support stand with a longitudinal adjustment mechanism to adjust an arthroscopic camera inward and outward within a joint, such as a shoulder joint to adjust field-of-view within the joint, (iii) arthroscopic instrument configured to apply a higher vacuum pressure, and (iv) arthroscopic working cannula with spreader members that, when spread from a closed position to an open position, form an expanded triangular area between the subscapularis and supraspinatus tendons.
