Causes of knee pain

Usually, knee pain and loss of mobility is caused by the joint’s cartilage lining wearing away. When this happens, the bones rub directly against each other, causing pain and swelling. One of the most common causes is osteoarthritis (OA), which often happens following trauma or direct injury to the knee. Without cartilage, there’s no ‘shock absorber’ between the bones in the joint, so stress builds up in the bones and causes pain and discomfort.
