Try to keep active with general exercise. Weight bearing exercise is recommended for osteoarthritis of the hip or knee joints. The key is to  be sensible, balance the weight-bearing stress by lowering the impact on the joint. Wear supportive shoes with modern cushioning. Using walking poles can significantly reduce the stress through your joints. Cycling and swimming are not thought to be impactful to the joints.  And… we LOVE Pilates here at the good exercise guide!
