• ‘Exercise is medicine’: exercise therapy reduces pain and activity limitations in osteoarthritis of the knee and is likely to have the same effects in osteoarthritis of the hip.

• Further research into exercise therapy is needed, since disease-modifying drugs are not available, pain medication can cause side effects, and surgical interventions are preferably applied in an advanced stage of disease.

• Classical exercise therapy is aimed at improving muscle strength, aerobic capacity, range of joint motion, and training of walking and activities of daily living.

• New modalities of targeted exercise therapy are currently being developed, aimed at the correction of low levels of activity and to correct instability of the knee.

• Weight loss, preferably combined with exercise therapy, reduces pain and activity limitations in osteoarthritis patients who are overweight.

• Modalities of exercise therapy adapted to comorbid conditions are currently being developed.
