AudreyH, Hi, I had double knee replacement many years ago. I tried a lot of things before the surgery, injections, etc. If I remember water therapy helped me the most. I enrolled at a YWCA, with my doctor prescribing it. Have you tried water therapy yet? If you have not, I would try it. If there are no classes that you can find, I suggest purchasing a book on the subject and finding a swimming pool to do the water exercises in. Don't be afraid, I put my surgery off for a long time, because I just did not want to have artificial knees. But when it got to the point that I could not walk, I did what I had to do. Investigate, because there are new knee replacements, that bend immediately after the operation, I am told. Much better than the ones I received, when my knees were replaced. I had to have therapy because my knees were in the shape of a V and had to be pressed down into an I, which was very interesting indeed. But I could not walk around like a duck with them in a V. I was walking three weeks after the surgery. You will be fine, it's just the anticipation. Read some of my other posts on this subject, for additional information. I made a promise that I have to keep, but there is something else that could help you. Cheers.
