Distal femoral clamp assembly and the distal femoral component having a cutting instrument

Cutting instrument for cutting the femur prior to implantation of the distal surface of the femoral component of total knee arthroplasty, comprising: a) an elongate shaft suitable for insertion into the intramedullary canal of the femur; b) capable of directing distal face of the femur distal femur cut cutting block; c) a distal femoral cutting block can be positioned on the left leg or the right leg clamp assembly distal femur, the distal end of the femoral component comprises a distal femoral jig clamp, the distal femur clamp comprises a lever for slidably receiving said at least one predetermined channel valgus angle, and is adapted to abut against the distal face of the distal femoral surface of the left leg or the right leg according to its two inverted orientation: a first inverted orientation, it said at least one rod in a selected channel is inserted with a predetermined valgus for left and right legs of the angle, and the second inverted orientation, the distal end of the femur fixture clamp around after flipping the longitudinal axis about 180 degrees, the rod can be inserted into the at least one channel having a predetermined valgus another for left and right legs of the angle of the selected.
