An old running injury had developed into bone-on-bone arthritis for our patient. She had a MAKOPlasty partial knee replacement. She reports that her recovery has been amazing. Six months after the operation she was on a hiking trip to Italy, hiking 10 miles a day up hills and on cobbled streets, on and off trains and buses. From day one she started PT and rehab. "I just would encourage anyone, if this is an option for your condition, to do it!"
