1. A system for performing a computer-assisted surgical procedure on a bone of a patient, the system comprising:
a first component and a second component configured to be selectively coupled to the first component in a predetermined spatial orientation, wherein at least one of the first component and the second component comprises a patient-matched surface configured to couple to the bone in a single spatial orientation, wherein at least one of the first component and the second component comprises one or more tracking markers joined thereto, and wherein a first from the first component and the second component is configured to be removed from the bone and a second from the first component and the second component is configured to be retained on the bone after the first is removed;
a tracking device comprising one or more sensors configured to detect a location of the one or more tracking markers;
a processor; and
a non-transitory, computer-readable medium storing instructions that, when executed by the processor, cause the system to:
receive the location of the one or more tracking markers from the tracking device, and
register a position of the bone based on one or more of the location of the one or more tracking markers, the single spatial orientation, and the predetermined spatial orientation.
