Move to Improve: How Knee Osteoarthritis Patients Can Use Exercise to Enhance Quality of Life.

Symptomatic knee osteoarthritis (OA) is a prevalent chronic degenerative disease that is associated with impaired quality of life and physical functioning. Although there is no cure for knee OA, regular exercise participation consistently results in improvements in quality of life, physical function, and knee OA symptoms. Findings from contemporary randomized controlled trials also demonstrate that lifestyle interventions involving modification of exercise and dietary behaviors yield superior improvements in relevant quality of life outcomes relative to either intervention alone.
