to all the answers. I think that I'll wait with Lilos surgery and see if it gets worst. Once her knee will reach 3rd stage than I'll do the surgery for sure. Untill than I'll just make sure, that she will not jump up and down from the furnitures. She doesn't seem in pain, so I think that I can put out the surgery for later. But I'll do it for sure, since it might cause athritise (sp?).
