Meniscal Root Repair

Meniscal root avulsions are a challenging injury causing meniscal extrusion and loss of hoop stress distribution, which can lead to the development of knee arthritis.¹ Securing the meniscus in a small bone socket has proven to be an effective means to restore hoop stresses and improve outcomes.² The FlipCutter^® II reamer and meniscal root marking hook allow for a minimally invasive RetroConstruction repair technique that helps preserve bone while securely fixing meniscal tissue.

A complete system for meniscal root repair includes the meniscal root marking hooks, the Knee Scorpion™ suture passer, and meniscal root repair kit with PEEK SwiveLock anchor. Arthrex offers two meniscus root marking hooks based on surgeon preference. The over-the-back marking hook sits securely over the back of the tibia to allow stable drilling using a 6 mm FlipCutter^® II reamer for socket preparation. The point-to-point guide allows surgeons to directly target their drill location at the meniscal root footprint. The low-profile Knee Scorpion instrument simplifies suture passing in tight recesses of the knee. Complete knotless fixation of the sutures with the 4.75 mm PEEK SwiveLock anchor.
