"Rheumatoid" is a medical word almost always used in the phrase "rheumatoid arthritis" - a disease where a person's own immune system attacks their joints by mistake, causing pain, swelling, and stiffness, often in the hands, wrists, and knees. This is different from the more common "," which comes from wear and tear over time, not the immune system. You will mostly meet this word in medical contexts - doctors, health articles, or when someone talks about a family member's illness.
