Abstract
Extrusion of the lateral meniscus has been reported after posterior root tear or radial tear, partial meniscectomy, and meniscoplasty of discoid meniscus. It has also been shown to be associated with the development of osteoarthritis. This technical note describes a new arthroscopic technique to centralize and stabilize the mid body of the lateral meniscus to restore and maintain the lateral meniscus function by repairing/preventing extrusion of the meniscus. A JuggerKnot Soft Anchor (Biomet, Warsaw, IN), loaded with a MaxBraid suture (Biomet), was placed on the lateral edge of the lateral tibial plateau, just anterior to the popliteal hiatus, through a midlateral portal. A Micro Suture Lasso Small Curve with Nitinol Wire Loop (Arthrex, Naples, FL) was used to pass 2 limbs of the MaxBraid suture through the meniscus at the margin between the meniscus and the capsule. Another anchor was inserted on the lateral edge of the lateral tibial plateau, 1 cm anterior to the first anchor, and the same procedure was repeated. The sutures were then tied by use of a self-locking sliding knot, achieving centralization and secure stabilization of the lateral meniscus.
