A computerized system and method is provided for stabilizing a first bone relative to a second bone during robotic based total joint arthroplasty. A plurality of cut paths are determined, either pre-operatively or intra-operatively using three-dimensional (3-D) virtual bone models, relative to the first bone and/or second bone in order to modify the bone(s) to receive an implant in a desired position and orientation. At least one stability region is identified between the two bones, where one or more cut paths are adjusted to avoid the at least one stability region. The first bone is therefore stabilized against the second bone at the at least one stability region while the remaining cut paths are executed around the stability region. Finally, the at least one stability region is removed once the reaming cut paths are completed and an implant is placed on the modified bone(s). |
