Knotless Medial Meniscus Posterior Root Repair

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Knee Biomechanics

Background:

• Medial meniscus posterior root tears are prevalent, particularly in Asian populations.
• These injuries disrupt knee biomechanics and can lead to arthritis if not addressed.
• Suture tapes offer robust tissue grip for meniscus repair.

Purpose of the Study:

• To describe an arthroscopic technique for repairing medial meniscus posterior root tears.
• To highlight methods for improved visualization and accurate suture anchor placement.
• To present a simplified repair method avoiding traditional drilling and knot tying.

Main Methods:

• Utilized a 70° arthroscope and a transseptal portal for enhanced posterior compartment visualization.
• Created a high posteromedial portal to optimize suture anchor trajectory.
• Employed a knotless suture anchor for fixation at the anatomic attachment site.

Main Results:

• The described technique facilitates secure fixation of the posterior root.
• Improved visualization aids in precise placement of the repair construct.
• Eliminates the need for transtibial drilling and complex knot tying.

Conclusions:

• This arthroscopic approach offers an effective method for medial meniscus posterior root tear repair.
• The technique simplifies the procedure by utilizing a knotless anchor and specialized portals.
• Restoring knee biomechanics through timely repair can help prevent arthritic degeneration.
