Summary
Transtibial meniscal root repair with centralization restores hoop stress and reduces extrusion, improving knee function. This technique offers durable relief and joint preservation for appropriate patients.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Biomechanical Engineering
Background:
- Meniscal root tears disrupt knee joint mechanics, increasing contact pressures and osteoarthritis progression.
- Prompt diagnosis and treatment are crucial to prevent degenerative changes after root tears.
Purpose of the Study:
- To describe and evaluate the efficacy of anatomic transtibial meniscal root repair with centralization.
- To assess the technique's ability to restore meniscal function and prevent extrusion.
Main Methods:
- Anatomic transtibial repair using luggage-tag sutures and knotless anchors.
- Meniscus centralization technique with a mid-coronal tibial plateau anchor to prevent extrusion.
- Knee flexion at 90° for suture tensioning and fixation.
Main Results:
- The technique restores hoop stresses and reduces meniscal extrusion.
- Patients report improved pain, function, and activity levels post-repair.
- Outcomes are superior compared to meniscectomy or nonoperative management.
Conclusions:
- Transtibial meniscal root repair with centralization is a reproducible technique for joint preservation.
- The method effectively restores meniscal function, minimizes extrusion, and delays osteoarthritis.
- Durable symptom relief and joint preservation are achievable in appropriately selected patients.
