I just had my right knee replaced on the 1st of March. I would have not had a problem sewing, except for the fact that I just wasn't in the mood to. If I am not in the mood I better not do it, cuz I will make a mess of what I am doing. I have been back to driving for the last week with no problems and am doing the PT 2 and 3 times per week. Also am going up and down basement stairs since week 2 and riding a stationary bike since the 2nd week. If you are determined you will do just fine.
