Does exercise therapy treat osteoarthritis?

Osteoarthritis changes the tissues around a joint and may cause pain, stiffness and reduced confidence with movement. Carefully selected exercise helps the muscles support the joint and keeps useful movement available. It can also make everyday tasks, such as standing, climbing stairs or walking, more manageable.

The programme depends on the joint involved, your symptoms and your general health. It may include range-of-motion work, strengthening, balance practice and low-impact aerobic activity. Exercise should be progressed gradually; the goal is a sustainable routine, not pushing through intense joint pain.

Start with a level you can repeat and allow time for your body to adapt. A physiotherapist can teach joint-friendly technique, choose alternatives during a flare and build strength around the affected area. Water-based exercise, cycling or walking may be useful for some people, while others need more targeted strengthening.

Pair exercise with the wider plan recommended for you, which may include weight-management support, pain relief or activity changes. Read more about Exercise Therapy to understand how a programme can be structured.

Contact a clinician if pain, swelling or stiffness is steadily limiting sleep, work or basic movement, or if the joint repeatedly gives way. Prompt assessment is needed after an injury that causes deformity or an inability to bear weight. A hot, very swollen joint with fever needs urgent medical attention.

Ask which exercises suit the affected joint, how much discomfort is acceptable, and how to modify activity during a flare. Clarify how often to practise, what improvement should look like, and whether weakness, locking or swelling suggests another problem.
