    • 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.
    • 使用手术导航在关节上执行关节镜手术的方法。 解剖学的3-D虚拟模型是从解剖结构的扫描创建的。 然后使用3-D虚拟模型来再现关节的运动并计划关节镜手术。 3-D虚拟模型被放置为与现实世界的解剖结构配准,使得由3D虚拟模型生成的虚拟图像可以被放置成与现实世界解剖结构的关节镜图像对齐。 优选地,在扫描之前定位的关节镜对准标记被用于将3-D虚拟模型放置在与真实世界解剖结构对准的位置。 关节镜对准标记物可经皮或关节镜放置。 在手术结束时,对准标记可以留在原位,关节镜去除或允许生物降解。
