At Johns Hopkins, several studies are currently underway to examine the role of factors such as physical activity, weight loss and arthritis education in reducing osteoarthritis-induced knee pain. We are also seeking to identify attributes of knee osteoarthritis disability. Johns Hopkins researchers are also analyzing the effects of alternative, non-operative treatments on osteoarthritis. One such treatment is glucosamine, a substance manufactured by the human body to build and repair cartilage, tendon and ligaments. Also available in the form of a dietary supplement, glucosamine has shown promise in relieving the pain of osteoarthritis. A long-term goal of Johns Hopkins researchers is to find disease markers that will allow for the early detection of osteoarthritis and possibly lead to the development of agents that will slow down or halt disease progression. |
