A study was conducted to find whether there existed any substantial link between knee/ hip injury in young adult life and subsequent development of osteoarthritis in the injured joints.
The study was done on 1321 men and women (the mean age of the participants at the start of study was 26 years and at follow-up was between 61-69 years) and they were followed-up for around 36 years. At the end of the study the diagnosis of osteoarthritis was done on the basis of clinical criteria or radiological findings (where available).
During the study researchers found that out of 1321 participants, 141 reported joint injury in adolescence or young adulthood (either in the knee, or hip or both). Out of these 96 developed osteoarthritis of hip or knee. Also the risk of developing osteoarthritis by the age of 65 years was 13.9% in those who had knee injury as compared to just 6% in those with no injury.
Hence, the study proves that people who have a history of joint injury in their early life have a significantly increased risk of developing osteoarthritis later on. Therefore, these people should definitely be targeted for the primary prevention of osteoarthritis
