Abstract

A method for intraoperatively planning and facilitating a revision arthroplasty procedure. The method includes capturing positions of a tracked probe as the tracked probe contacts an interface area between a bone and a primary implant component implanted on the bone, intraoperatively generating a virtual boundary corresponding to a portion of the interface area to be removed to detach the primary implant component from the bone using the positions of the tracked probe and without use of pre-operative medical imaging, facilitating removal of the primary implant component from the bone by providing a constraint on operation of a cutting tool while the cutting tool removes the portion of the interface area, the constraint based on a relationship between the cutting tool and the virtual boundary.
