  • Comparative analysis of different animal species, bone types, and defect creation methods.
  • Evaluation of scaffold, cell, and bioactive agent usage across studies.

    • Main Results:

    • Significant variability exists in reported animal models for long bone regeneration.
    • Differences in species, defect size, bone location, and surgical techniques complicate model selection.
    • No single model is universally optimal, necessitating careful consideration of research goals.

    Conclusions:

    • Selecting an appropriate in vivo model is essential for advancing skeletal tissue engineering.
    • Researchers must critically assess model parameters against their specific research questions.
    • Standardization and critical evaluation of models will enhance the reliability of bone regeneration research.
