2025 Review of 217 Trials Backs Aerobic Exercise for Knee Osteoarthritis

Summary
A 2025 BMJ review of 217 randomized trials covering about 15,700 people found aerobic exercise delivered the most consistent gains in knee osteoarthritis pain, function, walking and quality of life.
Walking, cycling and water-based exercise ranked above strengthening, flexibility, mind-body, movement-control and mixed programs, leading the authors to call aerobic activity a first-line intervention.
The study also stressed limits: most comparisons were indirect, long-term evidence was sparse and only 40 trials reported safety, so patients were urged not to push through sharp pain.
For day-to-day management, the report points to 10-20 minute level walks, low-resistance cycling, water exercise, simple leg and hip strengthening, and tai chi, which a 2022 40-person trial also linked to symptom relief.
The broader message is that knee osteoarthritis affects the whole joint, and regular low-impact movement plus weight management can reduce strain and preserve mobility even though worn cartilage does not regrow.
Since a massive 2025 study proves low-impact aerobics beats resting for knee osteoarthritis, have we been treating joint pain completely wrong all along?
If resting a painful knee actually worsens osteoarthritis, could AI-guided virtual physical therapy be the ultimate secret to breaking the stiffness cycle safely?
Beyond simple wear and tear, how do hidden inflammatory factors and obesity hormones quietly accelerate knee osteoarthritis despite regular exercise?
