What is osteoarthritis?

What is osteoarthritis?

Osteoarthritis is a condition caused by the degeneration of the articular cartilage, which acts as a shock absorber. When the cartilage thins or wears down, the joint surfaces rub against each other, causing pain.

Key characteristics of osteoarthritis:

  • Most common in older adults or those who use their joints for extended periods.
  • Often affects the knees, hips, and spine.
  • Pain is usually worse with activity and improves with rest.
  • Morning stiffness is common but improves quickly.

Osteoarthritis develops gradually with age and use, but its severity can be slowed with proper care.


What is inflammatory arthritis?

Inflammatory arthritis is a group of diseases caused by inflammation of the joints, which may be due to an autoimmune disorder or infection.

Examples of common types of inflammatory arthritis include:

  • Rheumatoid arthritis
  • Gouty arthritis
  • Infectious arthritis

Key characteristics of inflammatory arthritis:

  • Can occur at any age.
  • The joint is swollen, red, warm, and noticeably tender.
  • Morning stiffness often lasts for more than 30 minutes.
  • May experience fatigue or pain in multiple joints simultaneously.

Arthritis requires accurate diagnosis and treatment because if left untreated, it can lead to permanent joint damage.

What to do if you can't distinguish between the two?

The symptoms of osteoarthritis and arthritis may be similar in the early stages. Accurate diagnosis requires:

  • A thorough medical history and physical examination.
  • Medical imaging tests.
  • Blood tests in some cases.

Consulting an orthopedic specialist will help determine the underlying cause and ensure the most appropriate treatment.
