This 2000 NIH conference summary synthesizes expert consensus on what osteoarthritis actually is — pathologically, biomechanically, and biochemically — and catalogues the systemic and local risk factors that drive disease onset and progression, with emphasis on weight-bearing joints.
When evaluating a patient with early knee OA or at high risk (obese, post-injury, family history), target modifiable factors directly: even modest weight loss (~11 lbs) halves incident knee OA risk in women, and quadriceps strengthening reduces both prevalence and symptom odds — making these first-line prevention conversations, not afterthoughts.
Vitamin D deficiency is an underappreciated contributor to OA progression and worth checking in patients with rapidly progressive disease.
