Do exercise and self-management interventions benefit patients with osteoarthritis of the knee? A metaanalytic review.
OBJECTIVE
Osteoarthritis (OA) is the most prevalent health condition among seniors and it causes significant pain and disability. We assessed the influence of patient education and exercise regimens on the well-being of patients with knee OA.


METHODS
A metaanalysis was conducted on 16 studies reporting exercise and/or self-management interventions for patients with knee OA. The effects on physical and psychological well-being were assessed immediately after the interventions.


RESULTS
Compared to control conditions, exercise regimens led to improvement in physical health (by self-report and direct measures) and in overall impact of OA. Perceived psychological health remained unchanged by the exercise programs. Although the effect sizes for the self-management programs were significant for psychological outcomes and for the overall effect of OA, there was a significant difference between self-management and control groups only in psychological outcomes.


CONCLUSIONS
Overall, both patient education and exercise regimens had a modest, yet clinically important, influence on patients' well-being.
