How effective is exercise therapy for osteoarthritis?

Osteoarthritis affects the tissues around a joint as well as the joint surface. A tailored programme may train muscles supporting the knee, hip, hand, or another affected area, alongside mobility and balance exercises. Stronger muscles can reduce the work demanded of a painful joint during stairs, standing, or reaching.

Exercise does not restore worn joint tissue, but it can improve how the joint is loaded and how you move around it. Mild effort or short-lived soreness may be manageable, while a clear flare that lasts should prompt an adjustment.

Ask a physiotherapist to match the starting level to your joint symptoms, other health conditions, and usual activities. Begin with controlled repetitions or short activity periods, then build gradually as recovery becomes easier. Include strength, range-of-motion, and suitable aerobic work rather than focusing only on the painful joint.

Use supports, footwear, or activity changes if they help you exercise with less strain. Notice practical gains such as dressing, walking, or getting out of a chair.

Seek medical advice for a hot, markedly swollen, or suddenly painful joint, especially with fever or feeling unwell. Arrange review after a fall or injury, or when the joint repeatedly gives way, locks, or loses function. Stop an exercise causing sudden severe pain and ask how to modify it.

Which joint movements and muscle groups need priority? How should I judge a useful training response versus an aggravation? What activity can I use on difficult days, and how will we progress the plan?
