Preclinical models for orthopedic research and bone tissue engineering.

Area of Science:

• Orthopedics
• Bone Tissue Engineering
• Preclinical Research

Background:

• Rodent models are crucial for evaluating orthopedic treatments and bone regeneration strategies.
• Existing literature lacks a comprehensive overview of commonly used preclinical models in bone research.
• Practical insights into animal surgery and experimental design are often missing in methodological papers.

Purpose of the Study:

• To broadly define and discuss preclinical rodent models used in orthopedics and bone tissue engineering.
• To provide practical commentary on animal surgery and in vivo experimental design.
• To serve as a primer for researchers new to preclinical bone studies.

Main Methods:

• Review of existing literature on preclinical rodent models for orthopedics and bone tissue engineering.
• Categorization of models including implantation, fracture, and critical defect models.
• Inclusion of practical experience in animal surgery and in vivo experimental design.

Main Results:

• Discussion of various rodent models, from biocompatibility testing to fracture healing.
• Highlighting key methodological papers and providing expert commentary.
• Brief overview of outcome measures and power calculations for study design.

Conclusions:

• The choice of preclinical model significantly impacts the relevance and informativeness of research outcomes.
• This review offers a valuable resource for researchers selecting appropriate models for preclinical bone studies.
• Emphasizes the importance of considering experimental design and outcome measures for robust bone research.
