Arthritis Statistics

From 2.5 million YLDs in 2019 tied to knee osteoarthritis worldwide to 1.71 billion YLDs from musculoskeletal conditions globally, this page shows why arthritis is a disability engine and what it costs people in real terms. It also links treatments and behavior strategies to measurable outcomes, from ACR and EULAR guideline recommendations for exercise and methotrexate to study findings like worse adherence when costs hit and pain improvements of about 1 point on a 0 to 10 scale after effective non-surgical knee OA care.

Arthritis and related rheumatic diseases caused 1.71 billion years lived with disability (YLDs) from musculoskeletal conditions in the Global Burden of Disease 2019 study, while osteoarthritis alone was linked to 2.5 million YLDs in 2019 from knee disease worldwide. Costs and care gaps are just as striking, with $72 billion in direct osteoarthritis spending in the US in 2017 and evidence that many patients still struggle with access, adherence, and effective self management. Let’s look at the dataset behind these figures, including treatment recommendations and real world outcomes that show where prevention and care are working and where they fall short.
