The Arthrex approach to meniscal repair and reconstruction is represented by meniscal fixation and transplant products, like the FiberStitch™ implant and the ZoneNavigator™ system with meniscal needles. Transplant systems include the Dovetail Meniscal Allograft Set and other products to accommodate alternative meniscal transplant techniques. For more detailed information on these products and meniscal repair and meniscal transplant techniques, visit our product and educational resources sections shown below.

Product

A product of relentless innovation, the FiberStitch 1.5 implant features a new, low-profile delivery needle, resulting in less tissue morbidity and smaller implants and providing stronger fixation compared to previous FiberStitch implants.1 The proven superiority of FiberStitch all-suture anchors for all-inside meniscal repair is evident when compared to traditional PEEK implant systems.2 Made with 2-0 coreless FiberWire® suture, soft anchors provide secure arthroscopic all-inside knotless meniscal repair.

FiberStitch™ 1.5 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

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

A knotless all-suture anchor, the SutureLoc implant is specifically designed for joint-line fixation of the meniscal root. This revolutionary anchor eliminates the need for a posterior medial portal, which is commonly used in direct tibial fixation techniques, making the repair more reproducible. The 2.4 mm cannulated drill pin leaves more bone intact while delivering the SutureLasso™ wire directly to the footprint of the meniscal root. Once the anchor has been passed, the 2 repair sutures can be passed through the tissue in a variety of stitch patterns. The knotless implant is retensionable, allowing surgeons to dial in their repair.
Features and Benefits
<ul>
 <li>Double-loaded knotless mechanism allows for 2 repair stitches with only 1 anchor pass, reducing steps from previous techniques</li>
 <li>Soft, all-suture implant</li>
 <li>Minimal bone removal with a smaller, 2.4 mm drill pin and no need to decorticate</li>
 <li>Simple, reproducible suture passing</li>
 <li>Suture tension can be controlled and adjusted under direct visualization</li>
 <li>Repair sutures are converted in line, eliminating the potential for the suture to cut into bone</li>
 <li>236.8 N of pull-out strength and 0.34 mm of cyclic displacement1</li>

Meniscal Fixation

Human

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

Secondary (C)

The segmental meniscus transplant technique addresses failed repair of the meniscus while avoiding total replacement. Patients who have irreparable defects can benefit from a partial replacement, completed using the segmental meniscus transplant technique, which provides the same tibiofemoral joint compartment biomechanics as an intact meniscus.1-3 This technique helps preserve the native biomechanical loading principles of the knee while keeping intact native hoop fibers.

Segmental Meniscus Transplant

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.
