1. An orthopaedic surgical instrument, comprising:
a first component including a housing, a support arm that extends posteriorly from a superior end of the housing to a posterior end, and a passageway that extends through the housing along a longitudinal axis, wherein the support arm includes a first channel having a first superior opening, a first inferior opening, and a first lateral opening,
a first plate coupled to the posterior end of the support arm of the first component, the first plate being shaped to be positioned on a proximal end of a patient's tibia,
a second component including a shaft positioned in the passageway of the first component and an arm extending posteriorly from a superior end of the shaft, wherein the arm of the second component includes a second channel having a superior opening, a second inferior opening, and a second lateral opening, wherein the first and second channels are (i) aligned with each other such that each of the first and second superior openings and the first and second inferior openings are aligned in a superior-inferior direction and (ii) configured to receive a portion of a ligament of the patient, and
a second plate pivotally coupled to a posterior end of the arm of the second component superior to the first plate, the second plate being configured to pivot about a pivot axis intersecting the longitudinal axis of the first component to tilt the second plate relative to the first plate,
wherein an inferior-superior distance is defined between the second plate and the first plate, and the second component is operable to be moved along the longitudinal axis relative to the first component to change the inferior-superior distance.
