Ankylosis, or Anchylosis (from Greek Î±Î³ÎºÏ…Î»Î¿Ï‚, bent, crooked) is a stiffness of a joint, the result of injury or disease. The rigidity may be complete or partial and may be due to inflammation of the tendinous or muscular structures outside the joint or of the tissues of the joint itself. When the structures outside the joint are affected, the term "false" ankylosis has been used in contradistinction to "true" ankylosis, in which the disease is within the joint.
