What Is the Difference between Osteoarthritis and Rheumatoid Arthritis?

The biggest snag I run into when I tell people that I have rheumatoid arthritis is that people often don’t know what that is. Usually, the response is something like, “So? My grandma has that.” Now, obviously it’s possible that grandmas have rheumatoid arthritis. I know quite a few who do. But this is usually said with the implication that everyone gets rheumatoid arthritis as they get older, which isn’t true. Instead, quite a few people get osteoarthritis as they age. So let’s figure this out and talk about osteoarthritis vs rheumatoid arthritis.

Arthritis patient and blogging Kate the (Almost) Great shares the answer to the question she gets the most: What's the difference between osteoarthritis and rheumatoid arthritis? She also shares who can get each and symptoms of each, as well as resources.

Osteoarthritis vs Rheumatoid Arthritis: What’s the Difference?

Osteoarthritis – Osteoarthritis is the type of arthritis that most people think about when they think about arthritis. Essentially, it’s general wear-and-tear of the joints. “It occurs when the protective cartilage on the ends of your bones wears down over time” (x). According to the Mayo Clinic, “the slick surface of the cartilage becomes rough. Eventually, if the cartilage wears down completely, you may be left with bone rubbing on bone” (x).

Rheumatoid arthritis – Rheumatoid arthritis is an autoimmune disease in which the immune system mistakenly attacks the body, mostly the joints but it can also attack organs, eyes, and skin (x).

The Mayo Clinic says, “Unlike the wear-and-tear damage of osteoarthritis, rheumatoid arthritis affects the lining of your joints, causing a painful swelling that can eventually result in bone erosion and joint deformity (x). The inflammation associated with rheumatoid arthritis is what can damage other parts of the body as well” (x).

While osteoarthritis only affects the joints, in 40% of rheumatoid arthritis patients, other parts of the body are affected, as well (x).

Who Has Osteoarthritis or Rheumatoid Arthritis?

Who might have osteoarthritis? According to the Mayo Clinic, some risk factors of osteoarthritis are age (which is why people tend to associate it with older people), obesity, joint injuries, genetics, or bone deformities (x). Additionally, having other bone or joint issues can lead to osteoarthritis (x). It should be noted that these are risk factors and not guarantees or limitations. You don’t need to be over 50 to have osteoarthritis. I know people who have it who were/are athletes or were in car accidents. And my ankle condition actually puts me at risk for osteoarthritis in my ankle.

What Is Considered a Chronic Illness? And Other Chronic Illness Basics

Who might have rheumatoid arthritis? According to the Mayo Clinic, some risk factors of rheumatoid arthritis are gender, age, family history, smoking, environmental exposures, and obesity (x). Women are more likely to have it than men, RA is more likely to develop between the ages of 40 and 60, and a family history of autoimmune diseases makes you more likely to have RA (x).

When I was diagnosed, I was the only family member on my dad’s side (that we know of) who had an autoimmune disease, but since then, others have been diagnosed with different autoimmune diseases. Additionally, certain environmental exposures such as asbestos and silica can lead to RA, although this is poorly understood (x).

6 Tips for How To Accept a Chronic Illness

Signs You Have Arthritis

Osteoarthritis symptoms: According to the Mayo Clinic, symptoms include pain during or after movement, joint tenderness when pressure is applied, joint stiffness first thing in the morning or after a period of inactivity, loss of flexibility, feeling or hearing a grating sensation when the joint moves, or bone spurs (x).

Specific joints with osteoarthritis might react slightly differently. For example, hip arthritis symptoms include pain in the groin area or sometimes on the inside of the knee or thigh (x). Knee osteoarthritis feels like grating or scraping when moving the knee (x). In the fingers, you might develop bone spurs around the affected joints, which can cause swelling, tenderness, and redness (x).

As you can see, symptoms can vary depending on the affected joint, so be sure to bring up your symptoms to your doctor, even if you think they might not be relevant.

Rheumatoid arthritis symptoms: According to the Mayo Clinic, rheumatoid arthritis symptoms include joints that are tender, warm, and swollen; joint stiffness that is worst in the morning and after periods of inactivity; and fever, fatigue, and weight loss (x). Usually, in RA patients, more than one joint is affected, including the small joints like the wrist, certain joints in the hand, and the feet (x).

Additionally, often the same joints on both sides of the body are affected (x). For example, both of my knees bother me. Only one has needed surgery, but both are affected. There are other RA symptoms that come from long-term high levels of inflammation in the body, such as eye dryness, mouth dryness, gum irritation, inflammation in the lungs, inflammation in blood vessels, and anemia (x).

Personally, a lot of my other chronic illnesses are due to my RA. It took 9 years since symptoms started before I received my diagnosis, and then it took another 2.5 years before I found a treatment that worked for me.

Resources for Arthritis Patients

Looking for some support whether you have osteo or rheumatoid arthritis? Here are some resources:

Arthritis Foundation – The Arthritis Foundation “helps conquer everyday battles through life-changing information and resources, access to optimal care, advancements in science and community connections. Our goal is to chart a winning course, guiding families in developing personalized plans for living a full life – and making each day another stride towards a cure. We also publish Arthritis Today, the award-winning magazine that reaches 4.2 million readers” (x). They work on advocacy, scientific discovery, helping and supporting arthritis patients, and connecting the arthritis community.

Arthritis National Research Foundation – The Arthritis National Research Foundation focuses mostly on, well, research! More specifically, “The Arthritis National Research Foundation provides arthritis research grants to scientists at major universities and research institutes across America. One- and two-year arthritis research grants allow these newer scientists to develop their important research to a stage where it can be continued and further supported by other national agencies” (x).

FAQ: Have you tried [insert supplement here]? As FAQ: Have you tried [insert supplement here]?

As with all things, what’s true for me might not be true for others. I’m sure there are plenty of RA patients who do respond well to supplements; I’m just not one of them. 

Additionally, at one point, I refer to being on chemo since 2012. As always, the chemo I’m referring to is Rituxan, which is my RA treatment. I do not have cancer nor have I ever claimed to. 

Video: Kate talks to the camera. Text at the beginning reads “FAQ: Have you tried [insert supplement here]?” and other text later reads “*24” to correct when she says “symptoms for 21 years”. There are captions.

Week 19 of #2026Weekly I’m not going to lie - my Week 19 of #2026Weekly 

I’m not going to lie - my life now focuses even more on maintaining my body. Trying to avoid foot surgery + keep my bone density up so I don’t break another bone for a while on top of all the other things I do to manage my 10+ illnesses … it’s a lot of work. I did go to actual work this week lol but my camera roll is all chronic illness stuff this week. 

1️⃣ The machine that will hopefully prevent surgery!!! Every day, I do 40 minutes of this ultrasound machine (20 min on 1 fracture, 20 min on the other) and it will speed up healing 🤞🏻🤞🏻🤞🏻 
2️⃣ Continuing my exercise routine per my endocrinologist. Up to 30 minutes of Pilates 4 days a week … and since I don’t do exercises requiring pressure on my feet, the cast comes off.

SHARING YOUR HEALTH EXPERIENCES PUBLICLY⁣⁣⁣ ⁣ I sh SHARING YOUR HEALTH EXPERIENCES PUBLICLY⁣⁣⁣
⁣
I share my personal health experiences online, which I find it somewhat easy to do because I've been talking publicly - albeit to a smaller audience - since my health problems started in 2001. ⁣⁣⁣
⁣
If you share something online, you need to be prepared for people to ask questions or argue with you. Should they? No. Will that stop them? Also do. ⁣
⁣
That's one of the reasons that talking online about what can be trauma is not easy or for everyone. That's why it's important to practice self-care and to consciously think about what you want to share online before you do it. ⁣⁣⁣
⁣
For example, I generally only talk publicly about a health situation once it has passed, especially if it's an emergency. I also make sure that I'm in a good place mentally before I talk about it. That way, I don't share things I'll regret sharing publicly later. It also helps me be less anxious about sharing these details.⁣⁣⁣
⁣
And I don't share everything! There's lot of stuff that I haven't talked about not only online but with people in real life. It might seem like I share everything I've experienced, but I don't. ⁣
