Arthroscopic Centralization Using Knotless Anchors for Extruded Medial Meniscus.

Area of Science:

• Orthopedic surgery
• Knee biomechanics
• Osteoarthritis research

Background:

• Meniscal extrusion indicates failure of load distribution, potentially leading to osteoarthritis progression.
• Current arthroscopic techniques may not fully address medial meniscus (MM) extrusion, particularly in posterior root tears.
• The posteromedial region, a common site of extrusion in MM posterior root tears, is challenging to access arthroscopically.

Purpose of the Study:

• To describe a novel arthroscopic centralization technique for medial meniscus (MM) extrusion.
• To evaluate the efficacy of knotless anchors in reducing MM extrusion at the posteromedial aspect.
• To restore MM function and prevent osteoarthritis progression.

Main Methods:

• Development of an arthroscopic centralization technique utilizing knotless anchors.
• Application of the technique for MM extrusion, specifically targeting the posteromedial region.
• Focus on restoring MM function through efficient extrusion reduction.

Main Results:

• The described arthroscopic technique efficiently reduces MM extrusion.
• Knotless anchors effectively address MM extrusion in the difficult-to-approach posteromedial region.
• Restoration of MM function is achieved, mitigating osteoarthritis progression.

Conclusions:

• This technical note presents an effective arthroscopic approach for MM extrusion using knotless anchors.
• The technique successfully reduces MM extrusion, particularly in challenging posteromedial tears.
• Restoring MM function via this method offers a strategy to prevent osteoarthritis development.
