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. Repairing a torn meniscus, with its poor blood supply and challenging tear patterns, can present quite a challenge. Arthrex provides multiple options for meniscus repair, including the revolutionary all-suture FiberStitch™ implant for all-inside meniscus repair and the ZoneNavigator™ system with 0.9 mm SutureTape for inside-out meniscus repairs. The Knee Scorpion™ suture passer can be used to arthroscopically place suture for a meniscus-based all-suture repair.

Procedure

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. Use the ergonomic handle to advance and retract 2-0 SutureTape with meniscal repair needles in 1 cm increments. 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.

Inside/Out Meniscal Repair

The ZoneNavigator™ System revolutionizes inside-out meniscal repair with single-handed control of needle placement. Use the ergonomic handle to advance and retract 2-0 SutureTape with meniscal repair needles in 1 cm increments.

The low-profile 3.2 mm Knee Scorpion™ jaw allows the passage of 0 and 2-0 FiberWire® suture in tight recesses of the knee. The one-handed, ergonomically designed suture passer is offered with reliable FastPass technology. FastPass Scorpion™ technology allows passing suture through tissue and capturing the suture in one simple pass, eliminating the need for the extra steps of suture retrieval and suture shuttling. Multiple different suture configurations are possible using the Knee Scorpion suture passer.

The Meniscal Cinch II technique 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 Technique

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 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 Arthrex offers multiple implant systems for meniscal root repair.&nbsp;
The SutureLoc™ implant allows for direct tibial fixation of the meniscal root. 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. Traditional transtibial implant systems using a FlipCutter® II reamer and multiple fixation options are also available.
A complete system for meniscal root repair includes the meniscal root marking hooks and the Knee Scorpion™ suture passer. Two meniscal root marking hooks are available, so surgeons can choose their preferred hook.&nbsp;
The point-to-point guide allows surgeons to directly target their drill location at the meniscal root footprint, while the over-the-back marking hook sits securely over the back of the tibia to allow stable drilling tunnel preparation. Use the low-profile Knee Scorpion suture passer to simplify suture passing in tight recesses of the knee.

Treat a wide range of meniscal pathologies with the latest innovation in meniscal repair—all-inside meniscus repair using FiberStitch™ all-suture implants. In this procedure, soft all-suture sheaths replace traditional hard plastic PEEK anchors to provide a secure repair. Four different FiberStitch needle configurations are offered to address various tear patterns. Arthrex techniques and implants that address meniscus pathology include inside-out meniscus repair using the ZoneNavigator™ system with 0.9 mm SutureTape; meniscus-based, all-suture repair with the Knee Scorpion™ suture passer; all-suture meniscus ramp lesion repair; the Meniscal Root Repair System; and additional techniques for meniscus extrusion.

The Double Bone Plug technique for meniscal tear/deficiency utilizes bone plugs that can either be prepared freehand or by using a coring reamer. The freehand technique is performed using rongeurs and a high speed burr. For detailed information about this technique and/or Arthrex products utilized in this technique, visit the educational resources tab or products tab below. The double bone plug technique for meniscal allograft reconstruction provides a method for implanting the meniscal allograft medially with rigid fixation at both horn attachments. It has been demonstrated that bony fixation and bony healing at the attachment site allows for the maintenance of functional hoop stress by the meniscal allograft.

Double Bone Plug Meniscal Transplant

The dovetail technique simplifies graft preparation with a time-saving series of cuts preparing the bone component of the graft to sit securely in the recipient semi-trapezoidal slot created in the tibia. A matching semi-trapezoidal shaped recipient slot created in the tibia with a series of step drills, rasps and dilators matches the bone block preparation. Subsequent peripheral graft fixation to the capsular rim with 2-0 FiberWire® achieves the goal of creating a solid meniscal allograft construct. Preferably performed for lateral meniscal incompetence, the dovetail technique anatomically recreates the normal lateral meniscal relationships within the knee.
