Knee Osteoarthritis Isn't Inevitable, Even With a Family History Knee osteoarthritis affects more than 30 million adults in the US, and it's often assumed to be an unavoidable consequence of aging or genetics. New guidance from Washington University School of Medicine challenges that assumption, highlighting genuinely practical, evidence based steps that can meaningfully reduce both risk and severity. What's actually happening in the joint: Knee osteoarthritis develops as cartilage, the tissue that cushions bones in the joint and allows smooth movement, gradually breaks down over time. As this protective layer thins, pain and stiffness can develop and worsen progressively. Beyond the joint itself, why this matters more broadly: Osteoarthritis can significantly affect activity levels, fall risk, mood, and overall quality of life. Difficulty moving can lead to missed work and lost income, and discourage physical activity altogether, which in turn raises the risk of other chronic conditions including heart disease, cancer, and diabetes.
