Greetings, sorry about your concern.
Rheumatoid arthritis can be stopped if not cured. Before looking at knee just look for inflammatory markers to see the current status of RA. Knee surgery is not always the solution right away. If you can send the x ray for me to look through will definitely help to identify how can you decide on surgery or just exercise. Lab tests to check inflammatory markers are
CRP HIGH, CRP LOW,
VITAMIN D 3 AND HOMOCYSTINE LEVEL
Next Steps
good well planned diet will help cure rheumatoid arthritis. get assistance from a physiotherapist who is expert in postural correction.
