Subadequate fitting of the current OTS femoral component sizes on the ML axis. The red dots represent the femoral system, named “P1” sizes, each dot represents one patient femur The 2 red lines were drawn at 3 mm from each size, for a given femoral AP dimension. The dots within the red lines are the one that have an appropriate fit the ones falling out have instead an inadequate fit in ML minus (overhang) or plus (underhang). It is assumed a perfect fit scenario falls for a given AP for a ML tolerance of +—3 mm
