Abstract
The invention relates to a method for reconstructing a femoral portion of a knee in a total knee replacement, the distal end of which has medial and lateral condyles and an intercondylar notch therebetween defining a distal patellar groove for the articulation of the patella with the femur during flexion of the knee. The method comprising the steps of: PA1 locating and drilling a hole in the intercondylar notch to access an intermedullary canal of a femur; PA1 installing a femoral alignment guide onto an intermedullary rod; PA1 inserting the intermedullary rod through said hole toward a proximal end of the femur; PA1 moving said femoral alignment guide into contact with the intercondylar notch of the knee; PA1 positioning a femoral cutting block relative to the alignment guide; PA1 securing the cutting block to the femur to align a guide surface of the cutting block at a predetermined proximal distance from said intercondylar notch; PA1 removing the femoral alignment guide and rod from the femur; PA1 resecting the distal lateral and medial condyles along a plane using the guide surface of the resection block as a resection reference, wherein the plane is displaced from what will be…
