Abstract:
1. In a system for providing revision knee surgery, and specifically the surgical implantation of a femoral component of a revision knee, the method comprising: reaming a distal femur of a patient to enlarge an intramedullary canal therein; inserting in said intramedullary canal a trial stein attached to a cutting block, said cutting block having a front surface and a back surface and further having a first set of incremental markings on the front surface thereof, wherein said trial stem is hingedly attached to said back surface of said cutting block by a cutting block bushing, wherein said trial stem is able to rotate through about 10 degrees laterally around a longitudinal axis running perpendicularly to the back surface of said cutting block, wherein said cutting block is able to adjust in an anterior-posterior direction by means of an adjustment screw, said adjustment screw being threadably engaged to said cutting block bushing; adjusting said cutting block by means of said adjustment screw to position said cutting block adjacent a maximal area as possible of said distal femur to an adjustment position; reading and noting said adjustment position by means of said first set of incremental markings on said front surface of said cutting block; using said cutting block to cut the distal femur to fit a femoral component bearing incremental markings thereon; removing said cutting block and said trial stem from said distal femur; affixing a bushing having an upper portion and a base portion to said femoral component bearing a second set of incremental markings, wherein said second set of incremental markings correspond to said first set of incremental markings, to said adjustment position by means of said second set of incremental markings; attaching a femoral stein to said bushing; and implanting said femoral stem and said femoral component into said distal femur.
