van Tunen JAC, et al. - Authors described the occurrence of risk factors for knee and hip osteoarthritis in a population of 29–59-year-olds and projected the correlation between persistent knee/hip pain and these osteoarthritis risk factors. They also ascertained the occurrence of osteoarthritis risk factors, including specific biomechanical risk factors, in those with lengthy persistent knee or hip pain. Findings suggested knee/hip pain was frequently seen within the last month in this population. They noted an association of the multiple known osteoarthritis risk factors with presence of knee/hip pain. In individuals with knee pain, joint injury and previous surgery were more common vs those with hip pain. A trajectory towards symptomatic osteoarthritis later in life was signified by joint injury and overweight during early adulthood. These findings supported the identification of groups at high risk of future symptomatic osteoarthritis.
