Meniscus Centralization in Medial Meniscus Posterior Root Repair

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Biomechanical Engineering

Background:

• Meniscal root tears, affecting 60-70 per 100,000 people, are increasingly recognized.
• Meniscal extrusion (>3 mm) associated with root tears contributes to degenerative cartilage damage and increased tibiofemoral stress.

Purpose of the Study:

• To evaluate the efficacy of medial meniscus centralization during posterior root repair.
• To assess the impact on meniscal extrusion and knee osteoarthritis progression.

Main Methods:

• Medial meniscus posterior root repair using a pullout technique.
• Meniscus body centralization with a knotless anchor and additional all-inside sutures for stability.

Main Results:

• Significant reduction in meniscal extrusion observed at 2- and 3-year follow-up.
• No cases of conversion to total knee arthroplasty were reported.

Conclusions:

• Medial meniscus centralization effectively restores meniscus anatomy and function.
• This technique helps prevent osteoarthritis progression by improving tibiofemoral contact surfaces.
