1. A method for aligning an acetabular prosthetic component in a patient's surgically-prepared acetabulum, the method comprising:
placing an alignment frame on a body of the patient in a reference position such that each of a plurality of contact feet of the alignment frame confronts a corresponding reference point of the patient's bony anatomy;
inserting an inserter sensor module into a cradle of the alignment frame while the alignment frame is positioned on the body of the patient in the reference position;
generating, by an orientation sensor of the inserter sensor module, alignment data indicative of the current orientation of the inserter sensor module while the inserter sensor module is received in the cradle; and
transmitting, by a communication circuit of the inserter sensor module, the alignment data to a display module, wherein the alignment data is usable by the display module to register the inserter sensor module to a patient coordinate system of the patient's bony anatomy.
