The Arthrex approach to meniscal repair and reconstruction is represented by Arthrex meniscal fixation and transplant products. Meniscal fixation solutions include the Meniscal Cinch, Meniscal Dart and Meniscal Needles. Meniscal Transplant systems include either the Dovetail Meniscal Allograft Set or the use of other miscellaneous Arthrex products to accommodate alternative meniscal transplant techniques. For more detailed information on these products and meniscal repair and meniscal transplant techniques, visit our products and educational resources sections shown below.

Knee

Product

The FiberStitch™ implant is an innovative all-inside meniscal repair system that replaces hard PEEK implants with soft suture sheaths. 2-0 FiberWire® suture provides secure arthroscopic all-suture meniscus repair. The ergonomic handle is designed for single-handed implant delivery and active implant deployment technology minimizes needle exposure beyond the meniscus, eliminating the need to past-point the needle.

FiberStitch™ Implant

The ZoneNavigator System revolutionizes inside-out meniscal repair with single-handed control of needle placement. 2-0 SutureTape with meniscal repair needles are advanced and retracted in 1 cm increments using the ergonomic handle. Cannulas attach to the handle to efficiently target specific zones of the meniscus.
Use the needle catcher to guide needles away from neurovascular structures. The concave, curved retractor efficiently retracts tissue and directs the needles for easy retrieval.

ZoneNavigator™ System

Pass 0 and 2-0 FiberWire® sutures in tight recesses of the knee with the Knee Scorpion suture passer and retriever. With the lowest profile jaw available (3.2 mm), this one-handed, ergonomically designed suture passer eliminates extra steps for suture shuttling and retrieval with reliable FastPass technology. Pass and capture suture in one simple pass and apply multiple suture configurations with the Knee Scorpion suture passer.

Knee Scorpion™ Suture Passer

The Meniscal Cinch II implant offers a linear deployment mechanism to provide ergonomic handling and simplicity. The low-profile cannula allows flexibility in tight locations in the knee and the crimped cannula supports active implant deployment. The 1 mm × 5 mm PEEK implants are secured by 2-0 coreless FiberWire® suture with a pre-tied, modified Weston sliding knot that tensions easily and facilitates secure, low-profile vertical or horizontal suture repairs.

Meniscal Cinch™ II Implant

The Meniscus Repair and Resection Instrument Set contains Arthrex’s most popular instruments to address various meniscus procedures including meniscal root repair, all-suture meniscus repair, or meniscus contouring. For protection, the instruments are held securely within the slotted silicone pads. A removable shelf uncovers an open area for placement of additional instrumentation.

Meniscal Repair and Resection Instrument Set

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.

Meniscal Root Repair

Ramp lesions, which are commonly associated with ACL injuries and are often misdiagnosed,1 disrupt the meniscotibial ligament and the posteromedial meniscus in the meniscocapsular zone. Disruption of the posterior horn of the medial meniscus could lead to excessive forces within the knee joint and surrounding structures.
The QuickPass™ SutureLasso™ suture passer is preloaded with a #2-0 FiberStick™ suture and is available with a left or right 25° curve and 1.5 mm tip.

Meniscus Ramp Lesion

Meniscal Fixation

Meniscal tears are one of the most common problems treated by orthopedic surgeons today. The meniscus plays an important role in knee stability and distribution of forces within the knee joint and therefore should be repaired whenever possible. Due to its poor blood supply and challenging tear patterns, repair of the torn meniscus can present quite a challenge. Arthrex provides a multitude of options — including all-inside, outside-in, and inside-out repair — to surgeons faced with treating the various types of meniscus tears.

For meniscal allograft transplant, the double bone plug technique involves medially implanting the meniscal allograft with rigid fixation at both horn attachments. The technique can also correct meniscal deficiency using bone plugs and minimally invasive suspensory fixation and allows the meniscal allograft to maintain functional hoop stress.

Double Bone Plug

The technique used with the Dovetail Meniscal Transplant Set creates a trapezoidal bone block allograft for a bone-to-bone interlock, requiring no additional bone graft fixation. The soft tissue/meniscus portion of the graft still needs to be sutured/fixed. The instrumentation easily and consistently prepares the patient's recipient trough and the trapezoidal shape of the allograft's bone block.

Dovetail Meniscal Allograft Set

Meniscal Transplant Systems

Meniscal transplant systems are designed for meniscal allograft implantation with rigid fixation at the horn attachments. Specifically, the Dovetail Meniscal Allograft Set fashions a trapezoidal meniscal allograft, which is more easily reproducible, for a bone-to-bone interlock with a patient’s similarly shaped tibial trough. Generally used for lateral meniscus transplants, the dovetail meniscus allograft can also be used for medial meniscus transplants.
