Abstract

Objective To evaluate the association between acute joint injury to the knee and knee osteoarthritis (OA).

Design Prospective cohort. Sample size=1,436. Men and women aged 40 years and older participating in the population-based Clearwater Osteoarthritis Study (1988–current) with biennial physical exams including serial radiographs. Radiologically confirmed knee OA=27%; self-reported knee injury=11%. Lawrence and Kellgren ordinal scale was used to determine radiological evidence of the study outcome, knee OA. Self-reported history of knee injury was used to determine the study exposure.

ResultsIndividuals with a history of knee injury were 7.4 (95% C.I. 5.9–9.4) times as likely to develop knee OA than were those individuals who did not have a history of knee injury.

Conclusion Acute knee joint injury appears to be a risk factor for the development of knee OA. Prevention strategies for OA should be targeted to those individuals with a history of acute knee injury. Copyright 2002 OsteoArthritis Research Society International.
