Osteochondral autografts

Comparison of fresh osteochondral autografts and allografts: a canine model.

BACKGROUND Osteochondral autografts and allografts have been widely used in the treatment of isolated grade IV articular cartilage lesions of the knee. However, the authors are not aware of any study that has prospectively compared fresh osteochondral autografts to fresh allografts with regard to imaging, biomechanical testing, and histology. HYPOTHESIS The imaging, biomechanical properties, ...

Osteochondral Autografts and Allografts in the Treatment of Focal Articular Cartilage Lesions

Focal chondral defects of the knee, either due to trauma or other conditions such as osteochondritis dissecans, often fail to heal on their own and may be associated with pain, loss of function, disability, and the long-term complication of osteoarthritis. The ideal resurfacing technique would eliminate symptoms, restore normal biomechanics of the knee joint, and prevent the long-term emergence...

Adrenal Medulla Autografts

In 1959, experiments were begun to provide a more physiological and permanent pacemaker for chronic heart block by placing an autotransplant of either adrenal medulla or thyroid gland into the ventricular myocardium of dogs with complete heart block. The original concept was that the small area of myocardium surrounding the endocrine transplant would be stimulated by relatively high local conce...

Peritoneal autografts in conjunctival replacement.

Twenty-eight rabbits underwent conjunctival replacement with peritoneal autografts. The grafted peritoneum acted as a scaffold for the remaining healthy conjunctiva which gradually replaced the grafted peritoneum. Peritoneum is not an effective conjunctival substitute as it does not survive in its own right. I should like to thank Professor Norman Ashton, FRS for his most helpful guidance and c...
