An orthopaedic surgical instrument for use in knee surgeries includes an elongated body (14), a pair of output shafts (42, 44), and a user control (36, 38). A first output shaft extends out from a first side of the body along a first output axis (62) substantially perpendicular to a longitudinal axis of the elongated body. A second output shaft also extends out from the first side of the elongated body along a second output axis (64) substantially perpendicular to the longitudinal axis of the elongated body. The user control is coupled to the elongated body near a first end and the first and second output shafts are situated near the second end of the elongated body. Each of the first output shaft and the second output shaft is configured to turn independent of one another in response to operation of the user control.
