I'm glad things are going so well, Mary. I completely agree with your surgeon, that your knee needs time to heal before exercising. My surgeon doesn't allow any PT at all for the first month after a knee replacement. He says your knee needs that time, to start on its journey of healing. For that month, we rest, ice and elevate our leg, and walk around the house. After that month, we just go to PT once every 2 weeks, where we are shown a few new exercises to do at home. His patients all do well and achieve good ROM, as I did, and he hasn't had to do a manipulation to help with ROM for the past 4 years. I think that speaks for itself.
