The knee is the largest joint in our body, composed of bones, cartilage, ligaments and fluid. The knee joint moves with the help of the muscles and the tendons. Any movement disability is a signal that one or more of these structures are hurt or diseased.

In most cases, the knee conditions are caused by an injury or a trauma to the knee. Some people are more prone to developing knee conditions than the others.

People with osteoporosis or arthritis have also increased chances of having additional problems with their knees.
