It truly is mind over matter Sam. Just keep doing what they tell you and more if you can. I had bi lateral knee replacement a year ago March, walked out on my own, never used a cain or walker, was back wheeling in less than three weeks. I think yours will take more rehab, due to all the repair work. They just cut mine off, hammered the new ones and stiched me up, 10 inch scars down the center of both legs. In less than two months was better than I had been in 20 years, ride my bicycle 120 miles a week. they have come so far recently on surgery, it is amazing. Glad all went well for you/
