1. A method of performing an orthopaedic surgical procedure, the method comprising:
securing an offset guide to an intramedullary orthopaedic surgical instrument by:
(i) inserting a connector located at a proximal end of the offset guide into an opening defined in a distal end of the intramedullary orthopaedic surgical instrument to prevent relative rotational movement between the proximal end of the offset guide and the intramedullary orthopaedic surgical instrument, and
(ii) engaging a sleeve with the intramedullary orthopaedic surgical instrument to secure the intramedullary orthopaedic surgical instrument to the offset guide;
attaching an offset indicator to a distal end of the offset guide by inserting a plug of the offset indicator into a distal aperture defined in the offset guide, wherein inserting the plug of the offset indicator includes receiving an alignment tab of the plug into a corresponding groove of the offset guide; and
rotating the offset indicator about a longitudinal axis extending parallel to, and spaced apart from, a longitudinal axis defined by the intramedullary orthopaedic surgical instrument to determine an offset orientation for a prosthetic femoral component.
