Abstract
The present invention provides a cutting guide for ostectomy of the medial and lateral tibial surface during knee surgery. The cutting guide comprises a guide block including an axial opening defined along the longitudinal axis of the tibial canal. The guide block being adapted for attachment to a tibial trial base including alignment holes for locating the proper degree of rotational alignment of the tibial trial base with respect to the longitudinal axis of the tibia to assure the proper varus-valgus orientation and anterior-posterior slope of the resected tibial surface with respect to the femur. A pair of blade slots are provided for guiding a cutting tool for making a wedge-shaped resection of the tibia to accommodate a tibial tray component having a preselected internal distal surface corresponding to that of the resected tibia. The blade slots are pivotally mounted for selectively adjusting the angular alignment of the blade slots with respect to the lateral-medial axis perpendicular to the longitudinal axis of the tibia.
