Arthroscopic centralization of an extruded lateral meniscus

Area of Science:

• Orthopedic Surgery
• Knee Arthroscopy
• Meniscal Repair

Background:

• Lateral meniscus extrusion is associated with posterior root tears, radial tears, partial meniscectomies, and discoid meniscus procedures.
• Meniscus extrusion can contribute to the development of osteoarthritis.
• Restoring lateral meniscus function is crucial for knee joint health.

Purpose of the Study:

• To describe a new arthroscopic technique for centralizing and stabilizing the mid-body of the lateral meniscus.
• To repair and prevent lateral meniscus extrusion.
• To restore and maintain lateral meniscus function.

Main Methods:

• Arthroscopic placement of two JuggerKnot Soft Anchors on the lateral tibial plateau.
• Use of MaxBraid suture passed through the meniscus margin using a Micro Suture Lasso.
• Tying sutures with a self-locking sliding knot for secure stabilization.

Main Results:

• Successful centralization and stabilization of the lateral meniscus mid-body.
• The technique effectively addresses lateral meniscus extrusion.
• Provides a method to restore and maintain meniscus function.

Conclusions:

• The described arthroscopic technique offers a viable solution for lateral meniscus extrusion.
• This method can help prevent osteoarthritis progression associated with meniscus extrusion.
• It provides surgeons with a new tool for meniscal repair and stabilization.
