I have had both knees done a year apart. My doctor had me start exercises about six weeks before surgery to make sure all muscles were strong. Went home about 9 hours after surgery. Did not even need to use a walker. Was driving in a week. I had full range of motion in 2 weeks. Use lots of ice, do the PT and a lot of walking and exercise at home. I was back to normal in about 8 weeks. I am one of the lucky ones who can get down on my knees to work if I have to, just can’t stay down too long.
