1. A system for preparing a physical joint in a patient, the system comprising:

  • at least one processor,at least one see through optical head mounted display, andat least one user interface,wherein the system is configured to generate a virtual surgical guide, wherein the virtual surgical guide is a virtual axis, wherein the virtual axis is a three-dimensional digital representation indicating a predetermined position, predetermined orientation, predetermined version, or combination thereof in relationship to at least one anatomic structure of the physical joint for at least one physical surgical tool, physical surgical instrument, or combination thereof,wherein the system is configured to display, by the at least one see through optical head mounted display, at the predetermined position, predetermined orientation, predetermined version, or combination thereof, the virtual surgical guide onto a surface of the physical joint,wherein the system is configured to adjust the display of the virtual surgical guide responsive to movement of the physical joint to maintain the display of the virtual surgical guide at the predetermined position, predetermined orientation, predetermined version, or combination thereof in relationship to at least one anatomic structure of the physical joint, wherein the system is configured to allow alignment between the at least one physical surgical tool, physical surgical instrument, or combination thereof, and at least a portion of the virtual surgical guide displayed by the at least one see through optical head mounted display,wherein the at least one physical surgical tool, physical surgical instrument, or combination thereof, is configured to perform a reaming, a drilling, a pinning, a burring, a milling, a broaching or an impacting of the joint,wherein the at least one see through optical head mounted display is registered in a coordinate system, wherein the at least one anatomic structure is registered in the coordinate system, and wherein the virtual surgical guide is registered in the coordinate system.
