1. An orthopaedic surgical instrument system comprising:
a surgical burring instrument,
an orthopaedic burring guide configured to guide the surgical burring instrument to resect bone from a trochlear cavity of a patient's femur, the burring guide including (i) a frame including a bone-facing side and outer side positioned opposite the bone-facing side, the frame defining a first opening and a second opening separate from the first opening, both the first opening and the second opening being shaped to guide the surgical burr to resect bone from the trochlear cavity of the patient's femur, (ii) a distal boss extending from the bone-facing side of an inferior end of the frame so as to be positioned inferiorly of both the first opening and the second opening, the distal boss including a passageway, and (iii) a base extending from a superior end of the bone-facing side of the frame, and
a guide pin sized to be received in the passageway of the distal boss and configured to align the distal boss with a surgically-prepared reference hole of the patient's femur.
