Consistency Over Intensity: Exercise Eases Osteoarthritis Pain, But Benefits Vary
A large umbrella review of systematic reviews and new trials finds that exercise modestly reduces pain in knee, hip, and hand osteoarthritis (about 6–12 on a 100-point scale) but often does not improve function more than doing nothing or placebo; exercise can be as effective as NSAIDs for knee/hip pain and is usually less effective than total joint replacement for pain and function. Limitations include lumping all exercise types together, not distinguishing supervised vs. unsupervised training, short study durations (~12 weeks), and not accounting for total weekly dose. Despite these caveats, regular exercise likely offers meaningful pain relief and broad health benefits, with long-term adherence and a target around 150 minutes of moderate activity per week providing the greatest gains; the best approach is the activity you can maintain consistently.
