Purpose: This study examined the effects of exercise programs on the pain and quality of life in patients with knee osteoarthritis. Methods: Electronic bibliographic databases of KiSTi, KoreaMed, KISS and KERIS were searched to identify studies of randomized controlled trials and non-randomized controlled trials. As a result, 1213 publications identified and 16 studies met inclusion and exclusion criteria. All studies examined for quality assessment of studies using Cochrane's risk of bias. Results: The 16 studies were eligible for inclusion criteria, then the meta-analysis was conducted to examine effectiveness of exercise programs on pain and quality of life in patients with knee osteoarthritis. The meta- analysis based on the random effect model showed that the exercise program was beneficial in decreasing pain (effect size .69; 95% confidence interval 0.45~0.91). Also, the exercise programs have been shown to be effective in significantly improving the quality of life. However, it was not statistically significant due to severe deviations of studies (effect size 1.06; 95% confidence interval -0.34~2.46). Conclusion: Exercise programs had positive effects on pain relief and improvement of the quality of life in patients with knee osteoarthritis, although the quality of life was not statistically significant due to severe deviations of studies.
