SANDY JO MALMON LIVED WITH T PAIN OF AN ARTHRITIC KNEE FOR 12 YEARS. SHE WORE A BRACE AND WALKED WI A CANE. EVEN HER CAREER AS A CELLIST WAS IMPACTED.>>WHEN I WOULD GET UP FROM PLAYING MY KNEE WOULD STAY IN , THE POSITION OF SITTING. IT WOULD NOT STRAIGHT NOW UNTIL 45 SECONDS LATER. EMILY: SHE WENT TO DR. JEFF ZARIN IN THE DEPARTMENT OF ORTHOPEDICS AT TUFTS MEDICAL CENTER AND WAS THEIR FIRST PATIENT APPROVED FOR ROBOTIC ASSISTED KNEE REPLACEMENT SURGERY. THE MAKO MACHINE TAKES UP ABOUT THE SPACE OF A PERSON IN THE OPERATING ROOM. DR. ZARIN USES THE SAME IMPLANTS HE ALWAYS DID BUT NOW, HE CAN PLACE THEM MUCH MORE PRECISELY.>>IT IS ALMOST LIKE HAVING X-RAY VISION FOR ME. REPORTER: THE ADVANTAGE IS THE SPECIFIC PREP WORK THE TECHNOLOGY ALLOW A CT SCAN CREATES THIS 3D MODEL. ZARIN CAN CHECK ALIGNMENT AND CORRECT IMBALANCES DOWN TO THE MILLIMETER, ALL BEFORE SURGERY>>MEASURE HOW TIGHT THEIR LIGAMENTS ARE AND HOW TIGHT THEIR LEG IS, THEN I CAN MAKE ADJUSTMENTS TO THE LEG AND THE TENSION IN THE SYSTEM. REPORTER ONCE HE’S DECIDED ON HIS PLAN, ZARIN AND MAKO’S ROBOTIC ARM GET TO WORK. ZARIN GUIDES IT AS HE CHECKS THE SCREEN. YOU CAN SEE THE BLUE RECTANGLE, THAT’S THE INSTRUMENT USED TO REMOVE THE PORTION OF BONE HIGHLIGHTED IN GREEN. NOTICE THE THIN GREEN LINES OUTSIDE THE LEG, BOUNDARIES MAKO WILL NOT LET HIM CROSS IT DOES NOT LET ME MAKE A MISTAKE AND TERMING OF GETTING OUT OF PLANE. IF I TRY TO PUT THE CUTTING TOOL IN A BAD PLACE OR OUT OF ALIGNMENT, BY A DEGREE OR MILLIMETER, IT. ME. REPORTER: THAT KIND OF PRECISION IS WHAT ZARIN SAYS COULD MEAN BETTER OUTCOMES FOR PATIENTS LIKE SANDY. HER SURGERY WENT VERY SMOOTHLY AND SHE’S ON THE ROAD TO RECOVERY, HOPING TO PLAY HER CELLO AGAIN SOON EMILY: DR. ZARIN HAS 50 MORE MAKO ASSISTED KNEE SURGERIES SCHEDULED FOR THE REST OF THE YEAR. HE SAYS ANECDOTALLY THE TECHNOLOGY APPEARS TO MEAN BETTER OUTCOMES FOR PATIENTS BUT THEY DO NEED MORE HARD DATA TO CONFIRM THAT. HE’S NOW WORKING ON A RESEARCH GRANT TO STUDY THE RESULTS. BEN: FASCINATING. EMILY: HE IS SO PASSIONATE ABOUT IT. IT COULD BE THE FUTURE OF SURGERY.
