ABSTRACT:
A patella milling instrument has a planar base with a fixed patellar clamping element formed thereon. A movable patellar milling element is slidably mounted on the base and is movable towards and away from the fixed clamping element. A drive element is operable between the base and the movable element for moving the movable clamping element. The drive element is actuated by a drive mechanism fixed in a handle of the device found at one end thereof and connected to a drive element which is also in the form of a ratchet element. A movable end mill type cutting element is mounted on a support arm supported by the base. The support arm is capable of movement in directions parallel to the plane of the base and is adjustable in a direction perpendicular to the base. The end mill has a drive shaft rotatably mounted in a bushing in an end of the support arm which drive shaft is rotatable by a power tool and capable of movement in a direction perpendicular to the plane of the base.
