Systems for augmented reality visualization for bone cuts and bone resections including robotics

A system of preparing a physical joint in a patient comprising:

• at least one computer processor configured to generate a virtual surgical guide, wherein the virtual surgical guide is a virtual plane, wherein the virtual plane is a three-dimensional digital representation indicating a predetermined resection, a predetermined varus or valgus angle, a predetermined flexion, a predetermined slope or combination thereof in relationship to one or more anatomic structures for aligning at least one physical surgical guide, physical saw blade, physical insert or combination thereof;
• and
• a see-through optical head mounted display configured to display at the predetermined resection, predetermined varus or valgus angle, predetermined flexion, predetermined slope, or combination thereof, the virtual surgical guide onto a surface of the physical joint visible directly through the see-through optical head mounted display, so as to superimpose the virtual surgical guide onto the surface of the physical joint,
• wherein the virtual surgical guide is configured to allow superimposition and alignment between the at least one physical surgical guide, physical saw blade, physical insert or combination thereof and the virtual surgical guide,
• wherein the at least one physical surgical guide, physical saw blade, physical insert or combination thereof are visible directly through the see-through optical head mounted display,
• wherein the at least one physical surgical guide, physical saw blade, physical insert or combination thereof are configured to perform or indicate one or more bone cuts of the joint, and
• wherein the one or more anatomic structures are registered in a coordinate system.
