Kildare here, I am doing much better. I was overdoing the exercises early on and that aggravated the swelling and stiffness. I am nearly 5 months post surgery for BTKR and I can see the light at the end of the tunnel. I look back 8 years and recall I had dreaded walking any distance because of osteoarthritis in both knees. Massaging knees from foot to thigh is certainly helping. My wonderful daughter is doing that for me. Also elevating the legs. My PR mentioned that there is a lot of research being done on heat being applied as well as icing. Thank God for bonesmart.org it has been very helpful. God Bless you all.
