Summary
Osteoarthritis (OA) is the single biggest cause of disability in Western society. Despite this, relatively little is known about the factors that effect disease progression. This will be the first extended follow up study of cartilage volume in people with early OA. This study will build on our existing work where we have developed a cohort study of adults with early knee OA. These people were initially recruited in 1997-8. An extensive data base of potential risk factors for OA has been collect ....Osteoarthritis (OA) is the single biggest cause of disability in Western society. Despite this, relatively little is known about the factors that effect disease progression. This will be the first extended follow up study of cartilage volume in people with early OA. This study will build on our existing work where we have developed a cohort study of adults with early knee OA. These people were initially recruited in 1997-8. An extensive data base of potential risk factors for OA has been collected and both X-rays of the knee and MRI have been performed at baseline and 2 years. Extending the follow up from 2 to 5 years will allow not only more precise estimation of rates of cartilage loss and assessment of risk factors, but also enable assessment of the assumption of linearity of cartilage volume loss. It will also be possible to partition the observed variability in rates of loss into true between-subject variability and within subject residual variability. This partitioning will provide valuable information for the design of future studies in OA, similar to the establishment of statistical design principles for patterns of loss in bone mineral density.Read moreRead less

However, there is a risk of injury during this participation and efforts need to be undertaken to reduce this risk so that spor is safe for all. Sports injury prevention efforts to date in Australia have been severely hampered by a lack of evidence supporting currently advocated countermeasures. This concern has been recognised by both the NHMRC and the Commonwealth Department of Health and Ageing. It is imperative that we formally evaluate the effectiveness of sports injury countermeasures in the context of broad community level participation in sport, in contrast to previous research focussed on professional sport, and begin to deliver the preventive measures to the community. Australian football is a popular sport throughout Australia and it is associated with more medically-treated injuries than any other sport. Knee injuries are particularly common and can have severe consequences. One of the most commonly recommended knee injury prevention strategies is a well-designed exercise training program. Despite their potential to significantly reduce injury rates, the effectiveness of exercise training programs to prevent knee injuries in football, and indeed in most other sports, has not previously been assessed but has been identified as a priority research area by the NHMRC. This project will determine the effectiveness of exercise training programs for preventing knee injuries in community-level football players by monitoring injury rates, player behaviours and player attitudes before and after the training programs are implemented.Read moreRead less
