1. A method for performing a hip arthroplasty procedure, the method comprising:
mating a registration guide to an anatomy of a patient, the registration guide customized to the anatomy of the patient by locating a plurality of landmark locations within a plurality of two-dimensional images of the patient's anatomy, the plurality of landmark locations defining an oriented workspace for a joint arthroplasty procedure;
establishing, based on a position and orientation of the customized registration guide, a default position and orientation of an implant for use in the joint arthroplasty procedure, the position and orientation of the customized registration guide defining the oriented workspace for the joint arthroplasty procedure; and
attaching, via an attachment mechanism, a configurable bone-mounted robotic-assisted system to at least one guide pin attached to an anterior inferior iliac spine of the patient's anatomy in the oriented workspace for the joint arthroplasty procedure, the attachment of the at least one guide pin based on a pin guide of the customized registration guide, the robotic-assisted system comprising a robot controller in communication with a bone-mounted robotic device, an acetabular reamer connected to a motor controlled by a motor controller, and a torque sensor in communication with the robot controller,
wherein the customized registration guide comprises:
a circular portion;
a triangular portion extending from the circular portion;
an elliptical mating feature extending from the triangular portion and contacting anatomy of the patient at a junction of a pubis and ilium near the anterior inferior iliac spine to prevent the guide from rotating during joint arthroplasty procedure when mated; and
at least three cylindrical mating shapes extending from the circular portion and in contact with a rim of an acetabular portion of the patient's anatomy when mated.
