Aw...thank you. It took me so long to get to the point of accepting an operation...so now I have to live through the recovery to the best of my ability. But now that you mention it, I will ask a younger friend to help me upload those pictures. Actually the knee doesn't look different than the other knee but it sure is painful when I move. And that's my question to the doctor who is incommunicado now because he's so famous/popular in these parts -- he has a large staff but I'm guessing the best they can tell me is that, 'yes, there can be side effects from the operation -- people progress at different rates, etc.' So we'll see, I'll let you know. I can't figure why I can't figure how to upload the photos, however, I'll work on it. But the swelling doesn't show much at all, so it's a waste of time for me to upload it, but anyway maybe I'll learn how to upload photos from this phone. It's the pain there by the knee that bothers me and I wonder why.
