Abstract
The method for performing an arthroscopic procedure on a joint using surgical navigation. A 3-D virtual model of the anatomy is created from a scan of the anatomy. The 3-D virtual model is then used to reproduce motion of the joint and plan the arthroscopic procedure. The 3-D virtual model is placed into registration with the real-world anatomy, so that a virtual image generated by the 3-D virtual model may be placed into registration with an arthroscopic image of the real-world anatomy. Preferably, arthroscopic registration markers, positioned prior to scanning, are used to place the 3-D virtual model in registration with the real-world anatomy. The arthroscopic registration markers may be placed either percutaneously or arthroscopically. At the conclusion of the procedure, the registration markers may be left in place, removed arthroscopically or allowed to biodegrade.
