http://www.sanctifly.com/articles/what-exactly-is-arthritis/ Arthritis, in basic terms, entails joint inflammation. A joint is where two or more bones meet, for example, the hip or knee. The bones of a joint are addressed with a smooth, elastic material called cartilage. The cartilage plays as cushion to the bones, which enables the joint to act without pain.
