Compatibility of composite biomaterials in repairing bone tissue damage in sports competitions

Abstract

In sports competitions, bone tissue injury seriously affects athletes’ exercise levels, and some even cause lifelong regrets. With the continuous development of modern medicine, sports medicine has also been rapidly improved, and many tissue engineering techniques have been applied in the field of sports medicine. Used for the treatment of sports injuries, but the repair of bone injuries has always been a thorny issue in the medical field. This article mainly studies the compatibility of composite bio-nanomaterials in the repair of bone tissue damage in sports competitions. The method of constructing bone tissue engineering scaffolds is used to repair bone tissue damage, and the use of protein adsorption and wireless sensor compatibility methods to achieve composite bio-nanomaterials compatible, after 15 days of culture of PCL/PLA/HA nano scaffolds in vitro, stain the protein and observe the binding peptide sequence of the protein, and test the absorbance value. The results of the study showed that the growth rate of surface-bound peptides of nanomaterials was 1.2%, the absorbance value was 540 nm, and the hemolysis value of the experimental group was less than 5%. Biological compatibility is mainly related to the binding peptides on the cell surface, through intracellular and extracellular molecular signal transduction, and has a clear spatiotemporal sequence to optimize bone repair and recovery functions. Therefore, the use of synthetic nanomaterials to repair bone damage is a future trend, and biocompatibility is the key to this research.
