Arthroscopic Centralization of the Extruded Meniscus With Posterior Root Tear: A Technique Using Meniscotibial...

Meniscal root tears have been shown to significantly impact tibiofemoral mechanics and contribute to accelerated development of osteoarthritis. A common finding in conjunction with a meniscal root tear is extrusion of the meniscus. Meniscal extrusion is an independent risk factor for tibiofemoral cartilage loss and the progression of osteoarthritis. Meniscus centralization was first introduced to directly address extrusion alongside root repair techniques. To date, reported techniques for meniscus centralization generally involve anchoring the meniscus directly to the tibia in some fashion, which can limit the normal anatomic motion of the meniscus. We present a technique for meniscus centralization that aims to maintain natural meniscal motion by utilizing the meniscotibial ligaments.
