Knees are often taken for granted until they start to be painful. They are the reason that we are allowed to bend, sit, walk, run and stand or sit in an upright position. The hip is one of the largest weight-bearing joints in the body. Joints are formed by the ends of two or more bones connected by tissue called cartilage. Healthy cartilage serves a protective cushion, allowing smooth. Low-friction movement of the joint. If the cartilage becomes damaged by disease or injury, the tissues around the joint become inflamed, causing pain. With time, the cartilage wears away, allowing the rough edges of bone to rub against each other, causing more pain.
