When an articular cartilage is divided by incision or by being implicated in a fracture involving the articular end of a bone, it is repaired by ordinary cicatricial fibrous tissue derived from the proliferating cells of the perichondrium. Cartilage being a non-vascular tissue, the reparative process goes on slowly, and it may be many weeks before it is complete.

That the bullet which a drunken half-breed had sent into his chest two weeks before had nicked the arch of the aorta, thus forming an aneurism, was a statement by Cardigan which did not sound especially wicked or convincing to him. "Aorta" and "aneurism" held about as much significance for him as his perichondrium or the process of his stylomastoid.

The young bone is replaced by granulation tissue, so that large clear areas are seen with the X-rays. The symptoms are referred to the joint, because it is there that the muscles are inserted and drag on the perichondrium when movement occurs; swelling is most marked in the vicinity of the joint, and it may be added to by effusion into the synovial cavity.
