How does rheumatoid arthritis affect the knees?
From the Medical News Today website
Rheumatoid arthritis (RA) is an autoimmune condition, meaning the immune system mistakenly attacks healthy tissues. RA in the knees may severely affect a person’s mobility.
RA commonly affects the joints in the hands, wrists, and knees, causing the lining of the joints to become inflamed and damaged. RA is typically symmetrical, affecting both sides of the body equally.
There are around 1.5 million individuals in the United States with RA. They may have difficulty carrying out everyday activities, and if RA affects their knees, they may find walking, climbing stairs, and general mobility challenging.
If people do not seek treatment for RA, it can cause progressive inflammation, resulting in damage to the joints that can ultimately lead to permanent disability.
