Frequently asked questions

What are the best exercises for knee arthritis?

The best exercises for knee arthritis combine gentle range-of-motion work, strengthening of muscles around the affected joints, and low-impact aerobic activity such as walking, cycling or swimming. Start gradually and build up over several weeks.

Is it safe to exercise with knee oa?

Yes — for most people with knee oa, regular movement is one of the most effective self-management tools. Some short-term discomfort can be normal, but stop if you have sharp pain or sudden swelling and speak to a physiotherapist.

What exercises should I avoid with knee arthritis?

Avoid high-impact activities that cause sharp joint pain, heavy loaded movements without proper preparation, and anything that triggers swelling lasting more than 24 hours. A physiotherapist can tailor a programme to your joints and goals.

How often should I exercise with knee oa?

Aim for short, regular sessions — most days of the week — rather than long, intense workouts. UK physiotherapy guidance suggests building up to around 150 minutes of moderate activity per week, split into manageable sessions.

Can exercise reduce knee arthritis pain?

Yes — strong evidence shows that consistent exercise reduces pain, stiffness and fatigue in knee arthritis, while improving sleep, mood and overall function. Benefits usually appear within 6–8 weeks of regular practice.
