Knee OA risk factors across the life span
A systematic review and meta-analysis have helped to identify major risk factors for knee osteoarthritis in later life.
It is estimated that knee osteoarthritis (OA) affects around 23 per cent of the global population aged 40 years and over, with the individual lifetime risk for symptomatic knee OA as much as 45 per cent.
Knee OA is a leading cause of disability that also comes at a high cost; in Australia, $3.5 billion is spent annually on treating it and it results in a yearly productivity loss of $424 billion.
