[The structure of the hyaline cartilage in the plastic substitution of articular surface defects (an electron microscopic study)].

Results of the transplantation of the hyaline (articular) cartilage with the subchondral layer were studied in 100 mature rabbits. The transplants were treated by different methods. It was found that the hyaline cartilage of the articular transplants does not take part in reparative processes. It undergoes either partial or complete resolution. The resolution processes in auto- or allotransplantation of fresh transplants proceed longer and are characterized by gradual death of cell elements and by a destruction of the collagen structures. The demineralized osteochondrous transplants preserved in a week solution of formalin with kanamycin are closer to them in their terms and character of transformation. They are the material which should be recommended as most perspective for arthroplasty.
