A new randomized controlled trial out of India has found that vitamin D may be helpful in osteoarthritis of the knee.
Osteoarthritis is a degenerative joint disease. People with osteoarthritis have an imbalance between the synthesis and degradation of articular cartilage, which leads to the wearing away of cartilage. In consequence, people with osteoarthritis suffer from pain, tenderness and stiffness of joints.
For those with the disease, there are no medical remedies to deal with the debilitating aspects of the condition. If the disease has led to significant disability, joint replacement is an option.
How or why osteoarthritis develops is not well understood. Depending on age, sex and definition, anywhere from 4 to 30% of the population suffer from osteoarthritis, so any preventive or therapeutic measures taking on the condition are desperately needed from a public health standpoint.
