Joint pain, stiffness, and reduced mobility are among the most common reasons people seek medical care today. Two major conditions responsible for chronic joint problems are Osteoarthritis (OA) and Rheumatoid Arthritis (RA). Although both affect the joints and cause pain, they differ significantly in their origin, progression, and impact on the body.
At Oxford Hospital, our expert orthopedic surgeons and rheumatologists help patients accurately identify the condition and provide advanced, personalized treatment to restore mobility and improve quality of life.
What Is Osteoarthritis (OA)?
Osteoarthritis is a degenerative joint disease that develops gradually over time due to continuous wear and tear of the joints. It is the most common form of arthritis, especially among older adults. As joints are used repeatedly over the years, the protective cartilage that cushions the ends of bones begins to break down.
Cartilage plays a vital role in smooth joint movement by acting as a shock absorber. When this cartilage deteriorates, bones begin to rub against each other, leading to pain, stiffness, and restricted movement. Osteoarthritis usually affects joints that bear body weight or are used frequently in daily activities.
Common joints affected by osteoarthritis include:
- Knees
- Hips
- Spine
- Hands and fingers
Symptoms of Osteoarthritis
The symptoms of osteoarthritis develop slowly and worsen with time. In the early stages, discomfort may be mild, but without treatment, it can significantly affect daily life.
Key symptoms include:
- Joint pain that increases with activity and improves with rest
- Morning stiffness, usually lasting less than 30 minutes
- Reduced flexibility, making movements like bending or climbing stairs difficult
- Grinding or cracking sounds during joint movement (crepitus)
- Swelling and tenderness around the affected joint
- Bone spurs, which may appear as small hard lumps near the joint
Early diagnosis at Oxford Hospital helps slow disease progression and preserve joint function.
What Is Rheumatoid Arthritis (RA)?
Rheumatoid arthritis is a chronic autoimmune disorder, meaning it occurs when the immune system mistakenly attacks healthy tissues. In RA, the immune system targets the synovium, the lining of the joints, leading to persistent inflammation.
Unlike osteoarthritis, rheumatoid arthritis does not affect just one joint. It often involves multiple joints simultaneously and usually affects both sides of the body equally. If left untreated, ongoing inflammation can damage cartilage, bone, and surrounding tissues, resulting in joint deformities and disability.
RA is a systemic condition, which means it can affect other organs besides joints.
Symptoms of Rheumatoid Arthritis
Rheumatoid arthritis symptoms often appear suddenly and are more severe than those of osteoarthritis. Patients may experience both joint-related and general body symptoms.
Common symptoms include:
- Pain, swelling, and stiffness in multiple joints
- Symmetrical joint involvement (both hands, both knees, etc.)
- Morning stiffness lasting longer than one hour
- Persistent fatigue and weakness
- Low-grade fever
- Loss of appetite and unintentional weight loss
Because RA affects the entire body, early intervention by rheumatology specialists at Oxford Hospital is essential.
Other Health Complications of Rheumatoid Arthritis
If rheumatoid arthritis is not managed properly, it can lead to serious complications beyond the joints. Chronic inflammation increases the risk of several health conditions.
Possible complications include:
- Osteoporosis (weak and brittle bones)
- Carpal tunnel syndrome
- Lung, heart, and blood vessel inflammation
- Increased risk of heart disease
- Cervical spine involvement
- Sjögren’s syndrome (dry eyes and mouth)
- Rarely, certain types of lymphoma
Key Differences Between Osteoarthritis and Rheumatoid Arthritis
While both conditions affect the joints, their causes and patterns differ greatly.
At a glance:
- Cause: OA is due to wear and tear, while RA is an autoimmune disease
- Age of onset: OA usually occurs after 50, RA often begins between 30–60
- Joint pattern: OA is often asymmetrical, RA is symmetrical
- Morning stiffness: Short in OA, prolonged in RA
- Systemic effects: OA affects joints only, RA affects the whole body
Understanding these differences helps doctors at Oxford Hospital choose the most effective treatment approach.
Treatment Options at Oxford Hospital
Currently, there is no permanent cure for osteoarthritis or rheumatoid arthritis. However, early diagnosis and appropriate treatment can control symptoms, slow progression, and improve quality of life.
Non-Surgical Treatment Options
- Pain-relief and anti-inflammatory medications
- Disease-modifying drugs for RA
- Biologic therapies
- Physiotherapy and rehabilitation
- Lifestyle changes and weight management
Surgical Treatment Options
In advanced cases where joint damage is severe:
- Arthroscopic procedures
- Partial or total joint replacement surgery
- Advanced robotic-assisted joint replacement
Oxford Hospital offers end-to-end arthritis care, from diagnosis to recovery.

Conclusion
Osteoarthritis and rheumatoid arthritis may share similar symptoms, but they are fundamentally different conditions. Osteoarthritis develops due to joint degeneration, whereas rheumatoid arthritis results from immune system dysfunction.
Timely diagnosis and expert treatment can prevent long-term joint damage and disability. If you are experiencing persistent joint pain, stiffness, or swelling, consult the specialists at Oxford Hospital and take the first step toward a healthier, more active life.
