Patent ID: 8403935

Claim:
Apparatus for use in conjunction with knee joint-replacement surgery, the apparatus comprising: a rod adapted for intimate contact within an intramedullary canal of a femur following preparation of said canal to receive said rod, said rod including a threaded passageway extending longitudinally within said rod from a distal end, which is accessible when said rod is installed within said canal; a shaped body adapted for removable attachment to a distal portion of said femur, said shaped body including an outer surface configured to co-act in a joint and at least two bone-cutting guides defined through said body corresponding to a level of bone resection, including an adjustable trial/cutting guide having an anterior flange, a pair of posterior condylar flanges, a precisely threaded through-bore within an anterior notch, and a distal femur contacting surface, with a distal joint surface that corresponds to a natural distal femoral surface and condylar surfaces, wherein at least one guide slot is defined in portions of said anterior flange and said posterior condylar flanges that is sized and oriented so as to accept corresponding saw blades to allow for resection of bone, and further wherein a protrusion that projects outwardly from said distal femur contacting surface between posterior condylar flanges wherein said through-bore communicates between said distal joint surface and said distal femur contacting surface; and a vernier-bolt rotatably positioned through said body so as to be adjustably received within said threaded passageway thereby providing for movement of said body relative to said distal portion of said femur.
