Medial meniscus posterior root tear: a comprehensive review

Area of Science:

• Orthopedics
• Sports Medicine
• Biomechanical Engineering

Background:

• Medial meniscus posterior root tear (MMPRT) impairs knee function by affecting hoop strain, contact pressure, and kinematics.
• While various repair techniques exist, standardization and optimization of MMPRT treatment are lacking.
• Surgical planning requires consideration of pullout strength, degenerative changes, and alignment.

Purpose of the Study:

• To review and summarize current literature on MMPRT diagnosis and treatment strategies.
• To focus on controversies regarding the restoration of meniscus function and optimal suture techniques.
• To provide a comprehensive overview from basic science to surgical applications.

Main Methods:

• Literature review of diagnostic and treatment strategies for MMPRT.
• Analysis of studies focusing on surgical repair techniques, including suture anchors and pullout sutures.
• Evaluation of biomechanical and clinical evidence regarding functional restoration and arthritis prevention.

Main Results:

• Several MMPRT repair techniques demonstrate successful healing.
• Current trends favor repair using suture anchors or pullout sutures for indicated patients.
• Debates persist regarding the restoration of hoop tension and post-repair arthritis prevention.

Conclusions:

• Standardization of MMPRT treatment is needed.
• Further biomechanical and clinical studies are essential to address current debates.
• Optimizing repair techniques is key to restoring meniscus function and preventing knee arthritis.
