A newly published CDC study reports that a person’s lifetime risk for developing symptomatic knee osteoarthritis (OA) is nearly one in two, or 46%. The study authors also found that nearly 2 of 3 obese adults will develop painful knee osteoarthritis during their lifetime. Lifetime risk is the risk of developing a condition over the course of a lifetime. In this study, we defined lifetime risk as the likelihood of developing symptomatic osteoarthritis in at least one knee by age 85. The study provides what are likely the first lifetime risk estimates of knee osteoarthritis in the United States. Knee osteoarthritis—a common form of arthritis that wears away the cartilage cushioning the knee joint—is a leading cause of arthritis disability. In 2006, $18 billion were spent on hospital costs associated with total knee replacements. CDC led the study of lifetime risk and used data from the Johnston County Osteoarthritis (JoCo) Project, a study of approximately 3,200 residents, aged 45 years and older, in rural North Carolina. The JoCo Project, which receives CDC funding, is conducted by researchers at the Thurston Arthritis Research Center at the University of North Carolina, Chapel Hill. The JoCo Project is one of the largest long-term studies of knee and hip osteoarthritis in the United States, and is one of the first to include both blacks and whites.
