Physical inactivity is increasing worldwide despite strong evidence on its detrimental effects on health. Maintaining adequate levels of physical activity is especially difficult in older adults with osteoarthritis and resulting mobility limitations. While total knee replacements have been shown to be successful in relieving pain and improving health-related quality of life, it is not clear that they are successful in increasing physical activity levels. While there are tools that have been used in research that are known to be accurate in measuring physical activity in this population, these tools are expensive and difficult to use. It is not known if the newer personal activity trackers, which are less expensive and easier to use, are accurate to measure physical activity in this population.This study will measure physical activity levels in a group of older adults six months following total knee replacement with three different tools to see which tools are accurate and appropriate for use. Obtaining accurate information on physical activity levels in older adults following total knee replacement is a key step to ensuring this population achieves adequate physical activity levels for health benefits.
