ABSTRACT:
An apparatus for forming planar resections on the medial and lateral condyles of a femur includes a caliper feeler and measurement plate to measure for the size of the femoral prosthesis to be received, said caliper feeler and measurement plate adapted to determine a first distance between an anterior surface of the femoral cortex and a plane tangent to a posterior surface of the medial and lateral condyles of a femur. A graduated scale compares the first distance to at least two standard femoral prosthesis sizes and determines the smaller of the at least two standard femoral prosthesis sizes. A graduated scale measures a second distance between the first distance and the size of the smaller standard femoral prosthesis size, so that a thickness or thicknesses can be measured to be resected at the posterior surface of the medial and lateral condyles of the femur by adding the average thickness of the posterior condyles of the smaller standard femoral prosthesis and the second distance.
