Sixty-one patients ranged from eighteen to eighty years old underwent rigid internal fixation of supracondylar-intercondylar fractures of the distal end of the femur using 3 types of implant (DCS, condylar blade plate and condylar buttress plate). The congruity of the articular surface of the knee was anatomically reduced, as were the mechanical and anatomical axis of the lower limb. The time to clinical and radiological union averaged 3 months. There were 3 non union, 4 deep infection and 2 implant failure and one loss of fixation. The average range of motion was 117O. The average follow up period was 16.9 months. We concluded that the angle blade plate gave good result but technically is demanding and the need for hammering the implant puts risks separating the femoral condyles and must not used in the fixation of intercondylar fractures. Although the DCS improved reduction in sagittal plane it did not improve valgus-varus alignment much more than the condylar blade. It is prefered to use condylar buttres plate when there is inadequate bone stock or the quality of the bone is not sufficent to support the compression screw or condylar blade plate.
