ABSTRACT:
A distal femoral resector guide includes a generally T-shaped body with a saw guide at the distal end and a proximal stem structure. A rod extends from the saw guide and is intended to engage the intercondylar notch. The stem structure may be adjusted in length and includes a proximal end which may be shifted anteriorly and posteriorly with respect to the rest of the stem structure to accommodate distal femurs of differing configurations. A site line may be formed on the top surface of the stem structure and saw guide which includes an elongated groove filled with a material such as oxides of titanium which will glow under the presence of strong light. The inventive guide may be used in conjunction with a laser alignment mechanism to improve the accuracy of resection.
