Abstract
An orthopaedic joint replacement system is shown and described. The system includes a number of prosthetic components configured to be implanted into a patient's knee. The system also includes a number of surgical instruments configured for use in preparing the bones of the patient's knee to receive the implants. A method or technique for using the surgical instruments to prepare the bones is also disclosed.

A method of performing an orthopaedic surgical procedure, the method comprising:
- aligning a distal end of an intramedullary orthopaedic surgical instrument with a proximal end of an offset guide,
- positioning a connector at the proximal end of the offset guide in an opening defined in the 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 thereby advancing the intramedullary orthopaedic surgical instrument over the connector,
- engaging a sleeve with the intramedullary orthopaedic surgical instrument to secure the intramedullary orthopaedic surgical instrument to the offset guide,
- inserting the intramedullary orthopaedic surgical instrument into an opening defined in a distal end of a patient's femur,
- rotating a distal end of the offset guide about a longitudinal axis extending through the intramedullary orthopaedic surgical instrument to determine an offset orientation for a prosthetic femoral component,
- securing the distal end of the offset guide to a femoral cutting block including a plurality of cutting slots, wherein rotating the distal end of the offset guide includes rotating the femoral cutting block relative to a distal surface of the patient's femur, and
- attaching an offset indicator to the distal end of the offset guide, wherein rotating the distal end of the offset guide includes rotating the offset indicator about a second longitudinal axis extending parallel to, and spaced apart from, the longitudinal axis extending through the intramedullary orthopaedic surgical instrument.

A method of performing an orthopaedic surgical procedure, the method comprising:
- securing an offset guide to a femoral cutting block,
- inserting an elongated shaft of the offset guide into an opening defined in a distal end of a patient's femur, the elongated shaft extending along a first longitudinal axis,
- attaching an offset indicator to a distal end of the offset guide,
- rotating the offset indicator about a second longitudinal axis extending parallel to, and spaced apart from, the first longitudinal axis to rotate the femoral cutting block about the first longitudinal axis and determine an offset orientation for a prosthetic femoral component, attaching a first arm of a femoral positioning block to the femoral cutting block, and positioning a second arm of the femoral positioning block on a proximal end of the patient's tibia such that a predetermined gap is defined between the patient's tibia and the femoral cutting block, wherein rotating the offset indicator about the second longitudinal axis includes adjusting a distance between the patient's tibia and the patient's femur while rotating the femoral cutting block relative to a distal surface of the patient's femur.
