Brief description Osteoarthritis (OA) has the largest impact of any chronic disease on burden of disease borne in later life. This has been acknowledged by its listing as the 7th health priority in Australia. Knee OA is the most common reason for a joint replacement, thus imposing a huge financial burden to the community. Treatments which slow-prevent OA progressioning are limited and so prevention must play a key role. Obesity is the most significant, potentially modifiable risk factor for knee OA. The combination of the current epidemic of obesity in Western countries and the aging of the population is likely to have a synergistic effect on the prevalence and incidence of knee OA. Despite the consistent relationship between obesity and OA, little work has been done on the relationship between obesity and biomechanical factors such as knee angle and muscle mass and how these may interact with obesity and weight loss in modifying the risk of knee OA. It may be that weight loss programs could be more effective at reducing the risk of OA if they are combined with programs aimed at correcting muscle weakness and malalignment. This has the potential to promote a better quality of life as people age and to reduce the economic burden of knee OA in the community.
