Association of physical activity with physical function and quality of life in people with hip and knee osteoarthritis: longitudinal analysis of a population-based cohort
Authors' conclusion
These findings raise awareness of the importance of maintaining exercise/physical activity long term to optimize HRQoL and physical function.
