Three classes of proteins exist in articular cartilage: collagens (mostly type II collagen); proteoglycans (primarily aggrecan); and other noncollagenous proteins (including link protein, fibronectin, cartilage oligomeric matrix protein) and the smaller proteoglycans (biglycan, decorin and fibromodulin). The interaction between highly negatively charged cartilage proteoglycans and type II collagen fibrils is responsible for the compressive and tensile strength of the tissue, which resists load in vivo . Abbreviation: COMP, cartilage oligomeric matrix protein.

An injury and/or changes associated with aging might cause the cartilage cushion that covers the bones to wear away, causing pain as the bones of the joint rub together.
In addition, small nerves that branch out from the spinal nerves supply the facet joints. Irritation or pinching of these nerves also can lead to pain. Poor posture, which forces the spine out of alignment, can be a factor in the development of pain from the facet joints.
Trauma, inflammation, infection, and disc degeneration are other suggested causes of facet joint pain.
