The knees are happy but are still swollen so they have good moments and so, so moments. They are starting to bend very easy now so that is so cool. The pain I have now you can ice and get rid of but bone on bone is there until the arthritic joints are gone. So if you are wondering should I, I know only you can answer the question but for me it was YES. I still have problems but I can sleep all night, go for a walk, move around the apartment and am planning a trip. At times I think you question yourself - at least I did. Like will this really worth all this. Remember I am looking backward and then I look into the furture and see a wonderful tomorrow. Take care and do remember we care so please post and let us know how you are doing. This is a hard jouney and a difficult one, but don't be afraid. You are not alone. Take care Tashia
