Knee Osteoarthritis - Epidemiology Forecast - 2036

Knee Osteoarthritis Insights and Trends

• Knee osteoarthritis can affect both men and women; research suggests that women are almost twice as likely to develop osteoarthritis as men. About 63% of knee osteoarthritis cases in the US were contributed by the female population.
• Almost 10% of adults in the UK have been clinically diagnosed with Osteoarthritis. This is comparable to about 11.5% in the US and a slightly higher global prevalence of about 16%. The total number of cases of Osteoarthritis in the UK has increased over the years.
• Based on severity, most patients described their pain as mild, followed by moderate, and a smaller percentage reported severe pain.
• Increasing obesity and sedentary lifestyles contribute to the increasing prevalence of knee osteoarthritis globally.
• Those with multiple joints affected by synovial inflammation are more likely to have significant symptoms like higher levels of hand pain and stiffness.

Knee Osteoarthritis Epidemiology Forecast in the 7MM

• 2025 Prevalent Cases of Knee Osteoarthritis: ~51,495,300
• Knee Osteoarthritis Growth Rate (2026-2036): 1.8% CAGR

DelveInsight's 'Knee Osteoarthritis - Epidemiology Forecast - 2036' report delivers an in-depth understanding of the Knee Osteoarthritis, historical and forecasted epidemiology, in the United States, EU4 (Germany, Spain, Italy, and France), and the United Kingdom, and Japan.

Knee Osteoarthritis Understanding and Diagnosis Algorithm

Knee Osteoarthritis Overview and Diagnosis

Knee osteoarthritis, also known as degenerative joint disease, is typically the result of wear and tear and progressive loss of articular cartilage. It is most common in the elderly and can be divided into primary and secondary. Primary osteoarthritis is articular degeneration without any apparent underlying reason. Secondary osteoarthritis is the consequence of either an abnormal concentration of force across the joint, as with post-traumatic causes, or abnormal articular cartilage, such as rheumatoid arthritis. The symptoms of knee osteoarthritis develop gradually because it takes time for the cartilage to wear down and change how the joints work.

Knee Osteoarthritis Diagnosis

There is currently no standard lab test to verify the presence of knee osteoarthritis. Instead of a single lab test, physicians commonly use five diagnostic tools to determine if a patient has knee osteoarthritis or another medical condition. These tools are patient interviews, physical examinations, x-rays, MRIs, and lab tests for other conditions.

Knee Osteoarthritis Epidemiology

Key Findings from Knee Osteoarthritis Epidemiological Analysis and Forecast

• Amongst EU4 and the UK, in 2025, the highest proportion of age-specific cases was observed in those aged 70 years and above, followed by the age groups of 60-69 and 50-59 years.
• Among EU4 and the UK, Germany had the highest prevalence of cases of knee osteoarthritis, followed by France. In contrast, Italy had the lowest number of cases.
• In Japan, the age group of 70 years and above accounted for the highest cases. In contrast, the fewest cases were found in the age group of 18-39 years.
• In 2025, Germany had nearly 6,972,900 diagnosed prevalent cases of knee osteoarthritis.
• According to estimates, the United States accounted for the largest share of diagnosed prevalent knee osteoarthritis cases in 2025 within the 7MM.
