[Anatomical and histological study of osteochondral and costal cartilage autografts in the dog].

A macroscopic and microscopic anatomical study of the knees of 10 Beagles showed that thin osteo-chondral autografts taken from another joint healed perfectly macroscopically and almost perfectly histologically, if they fitted very well (figure 2). Rib cartilage grafts fitted perfectly to a dog's knee were not successful unless the perichondrium was turned towards the bone, in which case cartilage proliferated on the surface (figure 4). There was very little loss of substance but trans-chondro-osseus perforation also revealed a chondrogenic mode (figure 4). No trace was found in the literature of work concerning a comparison of these two types of grafts in the same experiment.
