I am around 260lbs and 5'7 and 43. I know I am young but I have hereditary bad knees and both are now arthritic. I can't walk any distance or stand up. I don't have too much pain unless I am weight bearing. I am a prisoner in my own home and don't have any way of getting outside as I am single. I work very little and often have to cancel at the last minute. I saw one orthopaedic surgeon who dismissed me, told me to go swimming and lose weight. It is very slow as I can't move, but I have lost around 20lbs. It's not enough though. I want to know if I would 1) benefit from knee replacements 2) should find a new surgeon who may be more sympathetic. I have auto-immune IBD which has also caused my other joints to be inflamed, especially both ankles, so my knees are really only half the problem. Any advice gratefully received.
