Rewritten paragraph: In fact, bone repair comprises two stages: bone growth and bone remodeling. The first stage involves the growth of new bone tissue in the initial implantation phase, where a scaffold with good support and stability is necessary to facilitate new bone growth. During the second stage, the scaffold’s newly formed bone tissue gradually transforms into mature bone tissue with load-bearing capacity under stress and strain. This requires the scaffold to possess certain elastic deformation, ensuring that the strain remains within an optimal range for new bone growth and strengthening. It is evident that the mechanical properties required for scaffolds in both stages of bone repair are different, if not contradictory. Therefore, resolving how biodegradable bone repair scaffolds can meet these different mechanical and biological requirements in both stages is crucial in achieving complete bone growth and reconstruction.
