What is Rheumatoid Arthritis and How Is It Different from Osteoarthritis?

Chances are if you are experiencing joint pain, morning rigidity, or swelling in your joints for a significant period of time, you have heard of rheumatoid arthritis (RA) and osteoarthritis (OA). Both conditions are a form of arthritis affecting your joints, and both can interfere with day to day living; however, they are very different in terms of causal agents, disease progression, and treatment. Understanding these differences is not just useful information, it is important to get the proper diagnosis and treatment to relieve your symptoms.
At Aastha Joints Clinic in Surat, we see many patients who confuse RA and OA. Many individuals delay getting treatment or simply ignore their symptoms because they are not aware of what type of arthritis they have. This complete guide will take you through everything you need to know to compare RA vs OA so that you can take the necessary steps to move without pain.

What is Rheumatoid Arthritis (RA)?

Rheumatoid arthritis (RA) is a chronic autoimmune disorder in which your immune system attacks the lining of your joints, leading to pain, inflammation and ultimately damage to those joints.
RA differs from osteoarthritis in that it is inflammatory – not caused by wear and tear. In RA, the symptoms usually start in small joints, like fingers and wrists, and will usually, but not always, affect both sides of the body in the same manner.

Key Features:
• An autoimmune disease causes the body to attack its own joints
• This disease occurs most often in women, aged 30-60.
• Symptoms include morning stiffness, joint swelling, fatigue, and a low-grade fever.
• If untreated, RA can cause permanent deformities in the joints and may involve other organs.

Why It Matters:
RA is a progressive disease that robs you of more than just your joints. Left untreated, the disease can have an impact on your life and ability to live independently. It is worth noting that most people who can show early detection and treatment of the disease can live normal active lives.

What is Osteoarthritis (OA)?

Osteoarthritis (OA) is the most common type of arthritis. Some people refer to it as “wear-and-tear” arthritis. Rheumatoid arthritis is an issue with the immune system. So, OA is mechanical and degenerative. OA occurs when the cartilage between the joints slowly wears away.

Cartilage is like a shock absorber; it allows your joints to move smoothly. When it starts to come apart, bones start rubbing. When this happens, you start to have affected joints that are painful, stiff, swollen, and grind.
Key Characteristics:

Mechanically caused: Typical due to wear-and-tear, aging, joint injury and/or obesity.
Commonly affected joints: Knees, hips, lower back, neck, hands, and base of the thumb.
Onset age: Typically starts after 45 years of age, more common as you get older.
Symptoms: Pain that worsens with activity, stiffness (worse after rest), limited range of motion, and bone spurs.
Progression: cartilage slowly continues to decline, creates friction and eventually bones touch one another and cause chronic pain and stiff joints.

OA does not involve the immune system, and clients usually have one side worse than the other side.

Rheumatoid Arthritis vs Osteoarthritis: Key Differences

Rheumatoid Arthritis (RA) and Osteoarthritis (OA) both affect the joints but in very different ways. It is important to understand these differences to ensure a proper diagnosis and treatment.

RA is considered an autoimmune disease as the immune system mistakenly attacks healthy joint tissue, causing inflammatory swelling and eventually damage to the joint over time. Typically, it starts between the ages of 30 and 60 and affects smaller joints, such as fingers, wrists, and feet, on both sides of the body. Other signs of RA include morning stiffness that lasts more than one hour, fatigue, and sometimes a fever or weight loss. If untreated RA can cause deformity and damage to internal organs.

OA, or osteoarthritis, is a degenerative joint disease that occurs due to normal wear and tear associated with aging. It commonly begins after the age of 45 and happens primarily in large joints that support weight, such as knees, hips, and spine. Typically one side of the body will be worse than the other. Pain is worse with movement and better with rest. Morning stiffness will not last long (less than 30 minutes). Unlike RA, OA does not cause fatigue or systemic feelings of fever.

Swelling that occurs with RA is also different in an important way. RA swelling is soft, warm, and results from swelling from inflammation; OA swelling is hard and bony from the breakdown of the cartilage and the production of bone spurs.

RA requires immune-modulatory medication and regular monitoring, whereas OA is managed with lifestyle modification, physiotherapy and, if required, procedures such as arthroscopy and/or joint replacement.

At Aastha Joints Clinic, we carefully consider these differences to ensure we get you the correct diagnosis and address your type of arthritis, not just your symptoms, in pemrograman!

How Doctors Diagnose Rheumatoid Arthritis and Osteoarthritis

For treatment to be successful, it is important to get the correct diagnosis. We at Aastha Joints Clinic use a combination of clinical assessment, diagnostic tests, and imaging procedures to determine what type of arthritis you may have.

RA:
• Blood tests for a rheumatoid factor (RF), anti-CCP antibodies, ESR, and CRP levels.

• Imaging tests such as X-rays, ultrasounds, or MRIs to look for signs of joint inflammation and joint erosion.

OA:
• X-rays will show degeneration as cartilage loss, bone spurs forming and narrow joint space.

• Physical Exam: will show tenderness, creaking sounds (crepitus), and how well the joints move.

Our orthopedic surgeon is very proficient in distinguishing between these conditions and customizing the treatment for each of these conditions.

Treatment Differences Between Rheumatoid Arthritis and Osteoarthritis

RA and OA are treated differently because they have different diseases.

RA Treatment:
• Medicines: DMARDs (Disease Modifying Anti-Rheumatics), corticosteroids, and biologics.
• Lifestyle: Exercise, maintain a balanced diet, smoke cessation.
• Monitoring: Regular check-ups to monitor visuals of markers of inflammation.

OA Treatment:
• Conservative Management: Weight management, physiotherapy, anti-inflammatory medications.
• Joint Injections: Hyaluronic acid or corticosteroids for pain to relieve inflammation
• Surgical Options: ACL tear surgery, arthroscopic surgery, and joint replacement when damage is severe

At Aastha Joints, our knee specialists provide ACL tear surgery and minimally invasive joint care for patients struggling with mobility due to OA.

Can You Have Both Rheumatoid Arthritis and Osteoarthritis?

Yes, it is possible to have both conditions. In fact, some older adults with long-standing RA can develop secondary OA due to joint damage. Distinguishing between the two becomes essential for tailoring the correct treatment plan.
