Claim:
1. A method of performing a total knee arthroplasty comprising: exposing bones of a knee of a patient; identifying a positional center of the knee using a knee center locator device; inserting a first pin into an anterior aspect of a distal femur and through the center of the knee; locating a femoral mechanical axis with reference to the center of the knee using a mechanical axis finder; inserting at least one additional pin into the anterior aspect of the distal femur, the axis of said at least one additional pin intersecting with and perpendicular to the femoral mechanical axis; locating a tibial mechanical axis using a tibial mechanical axis finder; sizing the femur using a femoral sizer positioned on at least one of the pins inserted into the femur; applying a femoral cutting block to a distal end of the femur, wherein the femoral cutting block comprises at least one femoral cutting guide; positioning a tibial cutting block in a cutting position relative to a proximal end of the tibia, wherein the tibial cutting block comprises at least one tibial cutting guide; aligning the femoral cutting block relative to the tibial cutting block; aligning the femur relative to the tibia; cutting the femur through the at least one femoral cutting guide; cutting the tibia through the at least one tibial cutting guide; removing the femoral and tibial cutting blocks; and positioning a permanent femoral knee implant component on the cut portion of the femur and positioning a permanent tibial knee implant component on the cut portion of the tibia.
