Abstract:

BACKGROUND: Advanced platelet-rich fibrin has been studied and prepared by scholars. Advanced platelet-rich fibrin has been proven to promote the regeneration and repair of autologous soft and hard tissues through animal experiments.

OBJECTIVE: To prepare advanced platelet-rich fibrin membrane and observe the histological changes of the diced cartilage grafts wrapped in advanced platelet-rich fibrin membrane and autogenous fascia.

METHODS: The following same procedures were carried out in 12 New Zealand rabbits: preparation of advanced platelet-rich fibrin membrane, collection of cartilage tissue of the left ear and the fascia tissue of the right hind limb of the rabbit. There were three types of cartilage grafts: diced cartilage; diced cartilage wrapped with autogenous fascia; diced cartilage grafts wrapped with advanced platelet-rich fibrin membrane. The grafts then were placed into subcutaneous pockets prepared on the backs of the same rabbits. The grafts were removed, and subjected to general observation and histopathologic examination 4 months after surgery.

RESULTS AND CONCLUSION: (1) The thickness of diced cartilage grafts wrapped with autogenous fascia and advanced platelet-rich fibrin membrane was thicker than diced cartilage grafts; the shape of the grafts was more rounded; and the surface was flatter. (2) The chondrocyte survival rate and regeneration potential of diced cartilage grafts wrapped with advanced platelet-rich fibrin membrane were significantly better than the other two grafts (P < 0.05). There was no statistical difference in the other histological parameters among the three types of cartilage grafts. (3) The results show that advanced platelet-rich fibrin membrane can improve the survival rate of diced cartilage and graft shaping and reduce the resorption of diced cartilage after transplantation.
