1. A method for performing a bone resection on a bone surface adjacent the knee joint with a cutting block comprising:

  • placing a cutting block having a cutting guide surface and an inner surface adjacent an anterior-medial quadrant or anterior-lateral quadrant of one of the bones forming the knee joint;

    positioning the cutting guide surface in a proximal-distal direction of the bone to set the depth of the resection prior to attaching the block to the bone;

    setting the angle of the cutting guide surface in one of the varus-valgus or flexion-extension angles prior to attaching the block to the bone;

    pinning the cutting block to the bone with a single pin after setting the angle of a longitudinal axis of said pin at said one of said varus-valgus or flexion-extension angles;

    rotating the cutting block on said pin about said axis to set the other of said varus-valgus or flexion-extension angles of said cutting surface;

    pinning the cutting block to said bone with at least one additional pin after setting said other angle; and

    resecting the bone surface using said cutting guide surface as a guide.
