Abstract: A system and method for intra-operatively measuring or verifying the placement of an implant within a bone in joint arthroplasty procedures are described herein. Pre-operative bone data of the patient is collected. A user plans the position of one or more implants relative to the pre-operative bone data. Intra-operatively, the patients bone is registered to the pre-operative bone data and to a computer-assist device. The bone is prepared and a physical implant is installed with the bone. A plurality of points are digitized on at least one of the physical implant or an apparatus associated with the physical implant. The computer-assist device calculates any errors between the planned position and orientation (POSE) of the implant relative to the actual POSE of the physical implant using the digitized points. The system may further notify a user of any errors and provide instructions to minimize the errors.
