Abstract

A method for performing a revision surgery using a robotic-assisted surgery system includes determining information related to an interface area between an implant component and a bone, and generating a planned virtual boundary associated with a portion of the interface area to be removed in a representation of the implant and the bone, based at least in part on the information related to the interface area. The method further includes tracking movement in the physical space of a cutting tool such that movement of the cutting tool is correlated with movement of a virtual tool, and providing a constraint on the cutting tool while the cutting tool removes the portion of the interface area. The constraint is based on a relationship between the virtual tool and the planned virtual boundary. The portion of the interface area is removed to remove the implant component from the bone.
