I had TKR on February 23, 2015, and it's amazing what I can do now. I "graduated" from PT last week, after going twice a week. I was pedaling on the bike for about two miles in ten minutes time. They had me doing weights, balancing, stretches, etc. A great program. I can now walk up and down the stairs without problem, walk several miles a day, and am pain free. The swelling is gone. The scar is still there, but is fading. There is a minor issue with numbness on the skin on the outside of my knee, but the area is getting smaller. If I overdo it, the outside edge of my knee will ache a little. I take no pain Meds. I can squat, hop a little, garden, carry things upstairs. If something is really heavy, I'll use the stairs, and put the box down, then put it up a few stairs at a time. It feels great to be able to walk pain free and limp free!
