advice the expert Katy Holden is senior musculoskeletal physiotherapist at london Bridge Hospital Q I have been diagnosed with osteoarthritis in my foot, and I am concerned that I will have to give up rambling. Is this definitely the case? Douglas, via email Katy Holden answers: osteoarthritis (oa) is a condition that affects the joints as we growolder, and it is estimated that 8.5 million people in the uK have it. The joint surfaces are usually covered by a layer of cartilage to protect the bone, and oais the loss of the protective cartilage layer at the end of the bones (the joint surfaces). The loss of this protective layer can lead to the joint motion not being as smooth as it was before, and can also cause pain and stiffness. it may seem counterintuitive to exercise with a stiff and painful joint; however, physical activity is a proven way to manage the symptoms of oa. it is important, though, that you try to maintain the flexibility in your leg and foot by performingregular stretches. i would encourage you to continue rambling, but ensure that you buildup yourwalking fitness sensibly and that you do not push through pain when your foot isalready aggravated.
