A mixed reality system comprising: a memory that stores at least a portion of a virtual surgical plan; a visualization device; and one or more processors configured to: display, via the visualization device and overlaid on a portion of an anatomy of a patient viewable via the visualization device, a virtual model of the portion of the anatomy obtained from a virtual surgical plan for an orthopedic joint repair surgical procedure to attach a prosthetic to the anatomy; and display, via the visualization device and overlaid on the portion of the anatomy, a virtual guide that guides preparation of the anatomy for attachment of the prosthetic, characterized in that the one or more processors are configured to: obtain, via one or more sensors (530, 532, 533) of the mixed reality system or of the visualization device, one or more dimensions of a glenoid of a scapula of the patient after the glenoid has been prepared for attachment of the prosthetic; obtain, via the virtual surgical plan, one or more dimensions of the prosthetic; compare the one or more dimensions of the prepared glenoid with the one or more dimensions of the prosthetic to determine whether the prepared glenoid has been properly prepared to receive the prosthetic; and output, via the visualization device, an indication of whether the prepared glenoid has been properly prepared to receive the prosthetic. a memory that stores at least a portion of a virtual surgical plan; a visualization device; and one or more processors configured to: display, via the visualization device and overlaid on a portion of an anatomy of a patient viewable via the visualization device, a virtual model of the portion of the anatomy obtained from a virtual surgical plan for an orthopedic joint repair surgical procedure to attach a prosthetic to the anatomy; and display, via the visualization device and overlaid on the portion of the anatomy, a virtual guide that guides preparation of the anatomy for attachment of the prosthetic, characterized in that the one or more processors are configured to: obtain, via one or more sensors (530, 532, 533) of the mixed reality system or of the visualization device, one or more dimensions of a glenoid of a scapula of the patient after the glenoid has been prepared for attachment of the prosthetic; obtain, via the virtual surgical plan, one or more dimensions of the prosthetic; compare the one or more dimensions of the prepared glenoid with the one or more dimensions of the prosthetic to determine whether the prepared glenoid has been properly prepared to receive the prosthetic; and output, via the visualization device, an indication of whether the prepared glenoid has been properly prepared to receive the prosthetic. display, via the visualization device and overlaid on a portion of an anatomy of a patient viewable via the visualization device, a virtual model of the portion of the anatomy obtained from a virtual surgical plan for an orthopedic joint repair surgical procedure to attach a prosthetic to the anatomy; and display, via the visualization device and overlaid on the portion of the anatomy, a virtual guide that guides preparation of the anatomy for attachment of the prosthetic, characterized in that the one or more processors are configured to: obtain, via one or more sensors (530, 532, 533) of the mixed reality system or of the visualization device, one or more dimensions of a glenoid of a scapula of the patient after the glenoid has been prepared for attachment of the prosthetic; obtain, via the virtual surgical plan, one or more dimensions of the prosthetic; compare the one or more dimensions of the prepared glenoid with the one or more dimensions of the prosthetic to determine whether the prepared glenoid has been properly prepared to receive the prosthetic; and output, via the visualization device, an indication of whether the prepared glenoid has been properly prepared to receive the prosthetic. obtain, via one or more sensors (530, 532, 533) of the mixed reality system or of the visualization device, one or more dimensions of a glenoid of a scapula of the patient after the glenoid has been prepared for attachment of the prosthetic; obtain, via the virtual surgical plan, one or more dimensions of the prosthetic; compare the one or more dimensions of the prepared glenoid with the one or more dimensions of the prosthetic to determine whether the prepared glenoid has been properly prepared to receive the prosthetic; and output, via the visualization device, an indication of whether the prepared glenoid has been properly prepared to receive the prosthetic.
