Knee osteoarthritis is no longer a condition seen only in older adults. In recent years, it has been rising rapidly among younger individuals due to sedentary lifestyles, obesity, and sports-related injuries.
• From 1990 to 2020, the number of people worldwide living with osteoarthritis increased from 256 million to 595 million — a 132% increase.
• People aged 27–45 now account for up to 25.5% of cases.
• Approximately 30% of individuals aged 20–40 are experiencing knee-related joint problems.
Common contributing factors today include:
• Prolonged sitting and physical inactivity
• Overweight and obesity
• Improper exercise habits
• Untreated or poorly managed sports injuries
According to projections, by 2050, the prevalence of knee osteoarthritis may increase by another 74.9%, becoming a major burden on public health and healthcare systems.
Don’t wait until pain appears to start caring for your knees. Staying active, maintaining a healthy weight, and seeking early medical evaluation when symptoms arise are key to protecting joint health in the long term.
