Among people with knee osteoarthritis, land-based therapeutic exercise provides short-term benefit that is sustained for at least 2-6 months after cessation.
Pooled results from 44 trials indicated that exercise significantly reduced pain (12/100 points; 95% CI 10-15) and improved physical function (10/100 points; 95% CI 8-13) to a moderate degree immediately after treatment.
Evidence from 13 studies revealed that exercise significantly improved quality of life immediately after treatment with small effect (4/100 points; 95% CI 2-5).
12 studies showed significantly reduced knee pain 2-6 months after cessation of formal exercise programmes (6/100 points; 95% CI 3-9).
