Rewritten paragraph: Bone repair comprises two stages: bone growth and bone remodeling. In the initial implantation phase, new bone tissue grows, requiring a scaffold that provides good support and stability to facilitate growth. As the newly formed bone tissue is gradually replaced by mature tissue in the second stage, which may be contradictory, the scaffold must possess certain elastic deformation that ensures strain remains within an optimal range for new bone growth and strengthening. Therefore, it is crucial to determine how biodegradable bone repair scaffolds can meet these different mechanical and biological requirements in both stages to achieve complete bone growth and reconstruction.
