Chris and Cariad: I sent the link to this thread to him so he could read about your recovery adventure stories, I think he is less anxious about that now, or at any rate more informed. I hope so. We have no knee brace, but will keep an eye out for same. He isn't on prednisone, today I learn that prednisone and prednisalone are different. [you truly need a medical degree to work all this out].Re Glucosamine. Yes well. I am from an old established hippy type family, and we are always on at Gregory to drink less diet coke and more tea, (he calls it "the tea propaganda machine") and to take things like Glucosamine. He resists. But I got his permission to try it after this surgery. I actually might try the liquid variety which I have heard is very good. But I will take it to DH's renal doctor first for the okay, good call. I bet you anything you like that after the dust has settled, it covers the once opened container of glucosamine.
