1. A system for monitoring a position of an orthopaedic instrument, the system comprising:
a first signal source configured to generate a first output signal during performance of a surgical procedure in which the instrument is being used;
a sensor configured to, during the performance of the surgical procedure, generate a data signal in response to the first output signal received from the first signal source; and
a controller electrically coupled to the sensor and configured to, during the performance of the surgical procedure:
determine a present position of the instrument based on the data signal received from the sensor,
retrieve position data indicative of a previously determined position of the instrument from a storage device, and
contemporaneously display indicia of the present position and the previously determined position of the instrument on a display device;
wherein the data signal uniquely identifies the sensor;
the controller is configured to, during the performance of the surgical procedure, identify a patient using the data signal that uniquely identifies the sensor; and
the controller is configured to cause the indicia to be displayed on the display device on image data of the identified patient.
