Abstract
A tibial alignment guide assembly for positioning a resection guide, the assembly including a main shaft having a proximal end and a distal end. The assembly also includes an anchor arm having an engaging end and a connection end. The connection end is preferably attached to the proximal end of the main shaft and the engaging end preferably has at least one anchor pin extending outwardly therefrom. The at least one anchor pin is adapted to anchor the tibial alignment guide assembly to a tibia plateau in order that the resection guide may be correctly aligned to the tibia. The assembly further includes a lever including an actuation end and a handle. The lever is pivotally connected to the anchor arm, whereby movement of the lever while the actuation end bears against the tibia plateau surface, causes at least a partial extraction of the at least one anchor pin from the tibia plateau.
