Abstract
Instrumentation for positioning a cut guide to cut a posterior slope in the tibial plateau surface of a tibia. The instrumentation includes an intramedullary alignment guide for engaging the tibia, and a rotational alignment guide for providing a guide for the insertion of a rod portion of the intramedullary alignment guide into an intramedullary bore in the tibia with the intramedullary alignment guide rotationally aligned with the intramedullary bore so that the longitudinal axis of a handle portion of the intramedullary alignment guide is angled posteriorly with respect to the longitudinal axis of the rod portion and the longitudinal axis of the intramedullary bore as the rod portion of the intramedullary alignment guide is inserted into the intramedullary bore.
