A robotic system for performing an arthroplasty procedure of a patient is provided. The robotic system includes a robotic mechanism including an adaptive arm, an oscillating saw coupled to the robotic mechanism and configured to resect a portion of a bone of the patient. The robotic mechanism is configured to control movement of the saw during the resection. The system also includes a computer coupled to the robotic mechanism which is configured to control the robotic mechanism. The robotic mechanism is configured to position a prosthetic implant relative to the bone. The system also includes an electric motor coupled to the robotic mechanism and the computer. The electric motor is configured to facilitate movement of the robotic mechanism. The system also includes a position sensor configured to provide movement information of the prosthetic implant relative to the bone. The system also includes an adaptive arm interface coupled to the adaptive arm and the computer wherein the adaptive arm interface is configured to operate the computer.
