    A SIZE 6 PS TRIATHLON BEADED FEMUR WAS PRESS-FIT INTO A PATIENT BUT THE CUTS MADE TO THE FEMUR BY THE MAKO WERE FOR A SIZE 5. THIS WAS NOT REALIZED UNTIL THE SURGEON VIEWED HIS POST OP FILMS AND SAW THE OBVIOUS CLEAR SPACE BETWEEN THE ANTERIOR FLANGE OF THE FEMORAL IMPLANT WITH THE ANTERIOR CONTEXT OF THE PATIENT¿S FEMUR. AT THE TIME THIS WAS BEING TYPED THE PLAN IS TO REVISE THE FEMUR AND POLY INSERT ON MARCH 4TH AT 6:30AM TO THE CORRECT SIZE 5 FEMORAL COMPONENT.
