Abstract: Apparatus and method for the preparation of the proximal tibia for resection at a selected resection level utilize an external alignment shaft having an exposed upper end for the reception of a tibial resection guide over the exposed upper end for movement downwardly along the alignment shaft, securement to the alignment shaft at a resection location along the alignment shaft, and affixation to the proximal tibia at the resection level, the alignment shaft having an upper rod detachable from a lower tubular member for withdrawal of the upper rod from the lower tubular member, and for withdrawal upwardly from the tibial resection guide while the tibial resection guide is maintained affixed to the proximal tibia at the resection location, for full access of the tibial resection guide to a resection device to accomplish resection of the proximal tibia.
