Abstract
The present invention relates to a method and instruments for resection of the distal femur. The instruments include a distal femoral resector and a femoral alignment guide/rod. The distal femoral resector is designed to be attached to the distal femur on a plane filed on the anterior femoral cortex. The distal femoral resector includes a feeler gauge laterally adjustable to adapt to the intercondylar notch of the particular patient and further includes a rotating rod having openings therethrough for fastening pins, which rotating rod is designed to facilitate the placement of the resector on the anterior femoral cortex in a flush manner. The femoral alignment guide/rod includes a plate insertable within a slot in the resector designed for the insertion of the cutting tool and further includes a pivotable rod which may be utilized to align the resector with the mechanical axis of the leg. The rod may then be pivoted to a position facilitating the insertion of a fastening pin through the resector. The method of operating using these instruments is also disclosed.
