Introduction

The terms “arthritis” and “osteoarthritis” are often used interchangeably, but they are not quite the same thing. Arthritis literally means joint inflammation,¹ and osteoarthritis is a type of arthritis.²

Joint problems are far more common than most people realize. The prevalence of arthritis in India alone accounts for 180 million, making it a condition more prevalent than diabetes or heart disease. It leads to chronic pain, joint deformities, and restrict the movements often making everyday activities difficult.³ In 1990, 23.46 million Indians suffered from osteoarthritis, and this number rose to 62.35 million by 2019.⁵

Patients often struggle to understand the difference between these two conditions because several joint conditions fall under the broad “arthritis” category.

Arthritis vs Osteoarthritis: What’s the Difference?

Arthritis is best understood as an umbrella term. It is defined as acute or chronic joint inflammation that often co-exists with pain and structural damage, and more than 100 different types have been identified.⁵ This umbrella includes osteoarthritis, rheumatoid arthritis, psoriatic arthritis, gout, ankylosing spondylitis, and arthritis associated with systemic lupus erythematosus.³

Osteoarthritis is one of the most common types of arthritis worldwide causing chronic pain and disability in adults.⁴ It is a degenerative joint disease in which the tissues within the joint gradually break down over time, and unlike many other forms of arthritis, it is not primarily driven by inflammation.^2,5 In essence, every case of osteoarthritis is a form of arthritis, but not every type of arthritis is osteoarthritis.

Recognizing the Symptoms

Symptoms of Arthritis ⁵	Symptoms of Osteoarthritis ^2,6
Pain, swelling, loss of function, stiffness, deformity, weakness, and instability May be accompanied by fatigue, sleep disturbance, emotional liability, and symptoms related to the underlying systemic illness Pain is typically worse with activity and toward the end of the day	Usually develops gradually, starting in one or a few joints Most commonly affects the hands, knees, hips, neck, and lower back Pain often flares with activity and eases with rest, though it may become more pronounced at night in later stages Morning stiffness, typically lasting <30 minutes A sense that the joint feels loose or unstable Gradual reduction in joint movement

Who Is at Risk?

Several factors can raise the risk of developing arthritis. Risk increases with age, and most types are more common in women, while gout is more common in men. A family history of arthritis, being overweight or obese, joint injuries, infections, and smoking can also contribute to the likelihood of developing the condition.⁷

Certain factors increase the likelihood of developing osteoarthritis. These include aging, being overweight or obese, a history of joint injury or surgery, repetitive overuse of a joint, joints that did not form correctly, and a family history of the condition. Women are at higher risk than men, particularly after age 50, and the condition often develops after menopause.^2,6

When Should Joint Pain Be Evaluated?

Joints should be evaluated for arthritis in case of ⁵

Persistent or worsening joint pain
Pain accompanied by swelling, stiffness, or loss of function
Pain worse with activity and toward the end of the day
Pain alongside fatigue or stiffness

Evaluation of osteoarthritis is done in case of ⁶

Persistent, worsening pain interfering with daily activities
Pain worse with activity, better with rest
Age over 45
Morning stiffness lasting under 30 minutes
Bony joint enlargement
Noticeable limitation in range of motion

Diagnosis and Management

Diagnosis begins with plain radiographs to find out joint space narrowing, osteophytes, and effusion. MRI may be used to get more details on synovitis, erosions, or sacroiliitis.⁵ Arthritis is a clinical diagnosis, confirmed by activity-related pain, age over 45, morning stiffness <30 minutes, bony enlargement, and limited range of motion.⁶

Treatment aims at reducing pain and minimizing the loss of function through non-pharmacologic measures such as avoiding activities that stress the joints, strengthening exercises, weight control, physical therapy, acupuncture, and use of supportive devices such as braces, splints, canes, or crutches. This can be combined with pharmacologic options including oral, topical, or intra-articular medications as required.^5,6

Key Takeaways

Arthritis is a group of joint conditions that involves inflamação. On the other hand, osteoarthritis is one of the types of arthritis resulting from slow joint tissue degeneration over time. Patient understanding towards this differentiation allows them to identify their symptoms bette and engage in moreinformed discussions with doctors about best course of action.

FAQs

Are arthritis and osteoarthritis the same?

No. Out of the more than 100 forms of arthritis, and osteoarthritis is the most common type that is non-inflammatory.

Is it possible to prevent osteoarthritis?

Risk factors such as overweight and overuse of joints, can be managed, but others such as aging and family history cannot be modified.

Can osteoarthritis be cured permanently?

No. Currently there is no cure for osteoarthritis. But a combination of lifestyle changes and treatment can help in managing the pain and preserve function over time.
