I am suffering from rheumatoid arthritis from past 9-10 years, my right knee got severely affected by it and it doesn't move in any direction it just got stuck and looks like a bended stick. My Dr. Who is an rheumatologist suggests me to get a knee replacement surgery as soon as possible but a surgeon told me that i would not get a knee replace as i am only 25 but i have rheumatoid arthritis in almost all my joints and my left knee has started affecting by it. And the surgeon told me that he would not conduct a total knee replacement surgery on my knee but he can operate my knee and make it straight like a straight stick of wood as my leg is slightly bended from knee but what is the benefit as my other knee has also started affecting by rheumatoid arthritis. What should i do ?

MRI and CT scan showed normal reports.sometimes increased pain causes a bit of a lump or swelling.have tried physiotherapy, homeopathy, heat patches, exercises nothing seems to help.how would I know if it's a spinal block compilation.?
