Abstract:

BACKGROUND: The methods used to repair articular cartilage defects currently have the cons and pros. Fibrocartilages are commonly used to repair tissues, and the fibrocartilage lacks of the tissue biomechanical properties and chemical properties of normal hyaline cartilage.
OBJECTIVE: To investigate the feasibility of biological osteochondral xenogenic graft transplantation to repair articular cartilage defects.
METHODS: The normal goats were randomly divided into two groups. The donor pig knee joints were the experimental group. Cylindrical osteochondral with the diameter of 4.5 mm and length of 10 mm were collected with the Smith & Nephew osteochondral transplantation device, and the patented technology was used for deantigen. The donor goat knee joint osteochondrals were the control group and preserved with cryopreservation. The lesions on femoral trochlea and weight-bearing surface of medial condyle were selected respectively for osteochondral implantation, and the animals were sacrificed at 16 and 32 weeks after operation for the general and pathological section observation.
RESULTS AND CONCLUSION: General observation in the experimental showed that the lesions were covered by fibroid tissue; some cartilage of the grafts turned yellow and there was clear boundary between the surface and the peripheral cartilages; the general and section observation under microscope showed that lesions of the control group were covered by the grafts basically, and cracks could be seen on the edge of the transplant part. The results show that there is difference between effects of biological osteochondral xenogenic graft transplantation and osteochondral allograft transplantation for the repairing of articular cartilage defects, and osteochondral allograft transplantation bas better effect.
