Ecchondroses.—These may be defined as small localovergrowths of cartilage. They are best studied along theedges of articular cartilages, the laryngeal cartilages, andthe triangular cartilage of the nose. Ecchondroses are especially common in the knee-joint,and often in association with the condition termed rheu-matoid arthritis. They are frequent in the joints of indi-viduals who have passed the meridian of life, and they occuras small projecting prominences along the margins of thearticular cartilage. Often the edge of the cartilage is pro-.

When these nodules are examined, many of thempresent on their outer surface a convex outline, but onthe inner aspect—that looking towards the joint—they areconcave, the concavity being produced by friction duringthe movements of the joint, or by pressure when theparts are at rest. Occasionally erosion of the ecchondrosismay extend so deeply that by some extra movement otthe joint the pedicle is broken, and the detached noduleeither falls as a loose body into the joint-cavity, or itmay be retained in position by its attachments to thefibrous structures of the articulation.
