Embodiments of the present invention allow unlimited rotational alignmentbetween two boundaries for alignment with anatomic landmarks while stillreferencing both posterior condyles for A/P sizing of the distal femur. Inparticular embodiments, the system provides at least one movable paddle thatprovides a reference point from the condyles so that the measuring assemblycan be aligned to be parallel with the epicondylar axis. Once the measuringassembly is properly angled, the A/P length of the bone can then be measuredfrom a proper reference point.
