Active youth are vulnerable to knee injury and subsequent osteoarthritis. Improved understanding of the association between health-related outcomes and history of joint injury could inform osteoarthritis prevention strategies. The purpose of this historical cohort study is to examine the association between youth sport-related knee injury and various clinical, physiological, behavioral, and functional health-related outcomes, 3-10 yr postinjury. ⋯ Youth that suffer a sport-related knee injury demonstrate on average more negative health-related outcomes consistent with future osteoarthritis compared with uninjured matched controls 3-10 yr after injury. These negative outcomes differ by sex and time since injury.
