Thank you for replying. Needless to say I am terrified. Hard with pain meds when I have to do all the driving. I am getting help coming Wed. With my husband thru VA so this will be a Hugh help. Something had to change. He is not happy with that but if I don't get well he will end of in a home this I do not want. I am healthy able to help him just need this knee taken care of properly. We have been married 51 years and I want the best for him. Thanks for encouragement.
