Thanks so much, everyone!
I have been wanting to get back into yoga- I was quite a practitioner, at one point. I put it off when the knee got bad lest I do some damage. Now I really should get out the mat and tapes again (and clear a space on the rug!)
I don't think I need anything heavy-duty yet, neither meds nor surgery- my mom just got her knee replaced and agrees with your wife, Doug- but just wanted to plumb the Wisdom of the 'Cat since I knew that there would be much to learn from y'all!
Kat, thanks for tellimg me about Zheng Gui Shui. I have a friend who owns a health food store- I'll ask her about it.
And thanks to all of you for the support!
