Subchondral cyst formation is characteristic of osteoarthritis and can be routinely found on x-rays. A subchondral cyst is a fluid-filled sac that extrudes from the joint, consisting of thickened joint material (mostly hyaluronic acid, a substance found in the normal joint fluid that serves to lubricate the joint). Subchondral bone is the layer of bone just below the cartilage.
A ganglion cyst is a sac filled with a jellylike fluid that originates from a tendon sheath or joint capsule. The word âganglionâ means knot and is used to describe the knot-like mass or lump that forms below the surface of the skin.
