Robot specific implant designs with contingent manual instrumentation

A method to design an implant and execute a robotic surgical procedure, comprising:

• providing pre-operative bone data of a bone to a computer having a pre-operative planning software program;
• planning a position for an implant having six or more planar surfaces relative to the pre-operative bone data;
• generating a set of instructions for a robotic surgical device to create six or more corresponding planar bone cuts to mate with complementary planar surfaces of the implant;
• and
• executing the set of instruction with the robotic surgical device.

A surgical system, comprising:

• a robotic arm controlling an end-effector;
• a computing system having one or more processors and memory, said memory storing a surgical plan having instructions for the robotic arm to actuate the end-effector to create six or more planar bone cuts on a bone, and wherein said one or more processors executes the instructions to control the robotic arm to create the six or more planar bone cuts with the end-effector;
• and
• one or more contingent manual instruments, each alone or in combination, create any remaining planar bone cuts in the event the execution of the instructions is aborted prior to the completion of the six or more planar bone cuts.
