Prevalence of Osteoarthritis
Osteoarthritis is one of the most common joint disorders worldwide. Its impact ranges from mild intermittent discomfort to severe pain, stiffness, and loss of mobility.
How common it is
- Global prevalence: approximately 10% of men and 18% of women over 60 years old have symptomatic osteoarthritis.
- Age-related increase: osteoarthritis becomes more common with age and is very frequent in older adults.
- Most affected joints: knees are most common, followed by hips, hands, and spine.
- Functional impact: osteoarthritis is a leading cause of pain, disability, reduced mobility, and lost productivity.
How it differs from other arthritis types
Osteoarthritis is distinct from other forms of arthritis such as rheumatoid arthritis (an autoimmune inflammatory condition), gout (crystal-induced), or psoriatic arthritis. While OA is primarily a degenerative disease, these other conditions involve systemic inflammation.
Why symptoms vary
The impact of osteoarthritis varies widely. In some individuals, it causes mild discomfort and minimal functional limitation. In others, it can lead to severe pain, mobility issues, and the need for assistive devices or surgical intervention. Early diagnosis and appropriate management are crucial to maintaining function and quality of life.
