Comparative biochemical analysis of platelet-rich plasma-chitosan and platelet-rich fibrin-chitosan for treating tibial bone defects in rabbits

Both combinations enhanced bone regeneration. However, PRF-Chitosan is a better combination for bone repair than PRP-Chitosan. There were some limitations of this study, such as a small sample size, only male rabbits were used, and a lack of mechanical testing; these limitations should be addressed in future studies. The insights gained from the present study may open a new approach to the use of a combination of biomaterials for bone healing, which should be further investigated clinically and in other animal models as a future scope.
