Knee Arthritis: Is Rest Actually Making It Worse?
Many people with knee arthritis stop walking because they fear cartilage damage. But is complete rest really protecting the knee? In this video, Dr Naveen Thiyagu explains why knee osteoarthritis is not simply “wear and tear,” why movement matters, and how the right dose of exercise may improve pain, stiffness, walking ability, and confidence. We also discuss a recent 2026 randomized trial on aerobic exercise intensity in knee osteoarthritis — including its findings and important limitations. *Key message:* Knee arthritis does not always mean stop moving. It often means start moving intelligently.
