Abstract: The milling guide of this invention provides a guide having a base with a track formed therein to slidably accommodate a milling device and guide the milling device along the bone. The milling device provides a smooth bone surface and the guide is provided to maintain the milling device generally transverse to the longitudinal axis of the tibia. A slider is carried by the track and accommodates the milling device to maintain the milling device generally perpendicular relative to the guide. The slider is shiftable within the guide in an medial-lateral plane. The milling device is shiftable relative to the slider and guide in the anterior-poster plane as well.
