The ideal insertion point for the blade plate is shown on the diagram. The
blade enters 1.5 cm above the distal end of the femur. It is possible to
position the plate slightly more distally than with a dynamic condylar screw
(DCS; 2 cm). The entry point for the blade plate is crucial. In terms of
anterior/posterior placement the distal femoral condyle should be viewed from
laterally. The distal femur is divided into thirds and the center of the blade
plate entry site is at the junction of the anterior one third and middle one
Insert the third guide wire just distal to the intended place of plate
insertion. This guide wire is parallel to the distal femoral articular surface
in the frontal plane, is perpendicular to the lateral femoral cortex and
parallel to the plane of the patello-femoral joint.
Note: There is a cannulated variation of the blade plate which has a guide wire
which runs through the blade itself. This cannulated blade makes insertion of
the device in the correct axis easier. This technique is not shown here.
