Establishment of a Rat Pull-Out Repair Model Demonstrating Fibrous Meniscus-Bone Healing and Suppression of Meniscal Extrusion After Medial Meniscus Posterior Root Tear

Key Points

• The research aims to create a reliable model to study the repair of medial meniscus posterior root tears and the associated healing mechanisms.
• Developed a rat pull-out repair model for medial meniscus posterior root tear.
• Assessed biological and biomechanical aspects of meniscus-bone healing.
• Evaluated differences in postoperative loading and rehabilitation conditions.
• Demonstrated effective fibrous healing of meniscus to bone.
• Showed reduced meniscal extrusion post-repair.
• Validated the model as a preclinical platform for future research.
