Abstract: A method and instruments for replacing the articulating surfaces of a knee joint in which the diseased area is restricted to one of the medial and lateral compartments. A femoral intramedullary rod is placed down the center of the femur. A femoral cutting block is affixed at one side to the rod and at the other side to an outrigger attached to the femur by smooth pins. The cutting block is adjustable rotationally and in the anterior-posterior plane. The cutting block is provided with surgical saw guide slots for the posterior and distal articular surface cuts and the chamfer cuts, all of which are made with the cutting block in place. The cutting block is removed and a drill guide is used for drilling two holes in the distal articular cut surface for receipt of the mounting pegs of the femoral unicompartmental prosthetic implant.

Abstract: A toilet tank cover comprises a frame to surround an existing toilet tank, brackets for mounting the frame onto the tank, and an actuator for flushing the toilet which replaces the existing flush handle. The frame preferably includes a reservoir lid to permit access to the interior of the tank. The actuator includes a chain which may be attached to the flush valve and which may be operated from outside of the frame. Preferably, a return spring is provided to return the chain to its normal position and allow the valve to close after the toilet is flushed.
