Procedure

There has been a renewed interest in ACL primary repairs as the treatment for Sherman type I and type II ACL ruptures. Careful analysis of historical data has revealed that certain ACL tear subgroups, especially proximal tears with good tissue quality, have positive clinical outcomes with primary ACL repair.1
Studies reporting outcomes of remnant-preserving ACL surgeries have shown encouraging results and a greater potential for early healing and better functional outcomes compared with remnant-resecting surgeries.2 Preservation of the native ACL using the primary repair technique can achieve short-term clinical success and result in good clinical outcomes at 3-year follow-up in this carefully selected patient population.3
Arthroscopic primary repair is minimally invasive because no grafts need to be harvested, no graft tunnels or sockets need to be drilled, and revision surgery, if necessary, is more analogous to primary reconstructions.4 The goal of the procedure is to preserve the remnant native ligament. By doing this, the native nerve endings and blood supply are preserved.5

Quadriceps tendon grafts offer unique benefits for cruciate ligament reconstruction, such as a predictably large diameter, low morbidity,1 and a preferable stiffness profile for knee ligament reconstruction.
The QuadPro™ tendon harvester is designed to harvest a quadriceps or patellar tendon graft using a minimally invasive technique.2-4 The sharp tip cores out an approximate cylindrical graft. The harvester's ergonomically designed handle features graduations on the clear shaft to allow visualization of approximate graft length during harvesting. Available in four sizes (8 mm to 11 mm), the QuadPro tendon harvester can accommodate each patient’s unique needs as well as the surgeon’s preference for graft diameter.
The FiberTag® TightRope® implant facilitates attachment of single-ended grafts, such as quadriceps tendon grafts, to the ACL TightRope RT and ABS implants. FiberTag suture is integrated into the TightRope implant for a strong, consistent connection between the suture and TightRope loop. A simplified suturing technique, along with innovative packaging and the GraftClamp graft preparation instrument, make preparing quadriceps tendon grafts faster and more reproducible than ever.

Quad Tendon Autograft ACL Reconstruction

Arthrex offers a comprehensive selection of fixation devices for a variety of bone-patellar tendon-bone (BTB) graft techniques. These options include adjustable, continuous-loop suspensory fixation, and interference screws in a variety of materials. The TightRope® implant, which has been used in 2 million procedures globally,1 was designed to simplify ACL reconstruction and facilitate advanced techniques, such as the GraftLink® technique. BioComposite FastThread™ interference screws, which are composed of time-tested material with more than a decade of clinical success and implantation, allow for faster screw insertion and better graft protection.2

BTB Autograft ACL Reconstruction 

Arthrex offers the most advanced techniques and instruments for hamstring harvesting and preparation for ACL reconstruction. A reproducible harvest can be performed through a traditional anterior or posterior approach using the minimally invasive hamstring harvest technique and specialized tendon strippers.
The GraftLink®&nbsp;technique provides an anatomic, minimally invasive, and reproducible ACL reconstruction procedure. When used in combination with anatomic guides, the FlipCutter® III drill allows independent femoral and tibial "retrodrilling" to create sockets while maintaining the cortices to maximize fixation. Femoral and tibial TightRope® II implants, with a proprietary 5-point locking system, make the GraftLink technique the most reproducible ACL reconstruction available.
Anatomic: Independent tibial and femoral socket preparation with FlipCutter III reamer and/or low-profile reamers facilitate unconstrained placement of the ACL graft.
Minimally Invasive: Socket preparation with the FlipCutter III reamer limits soft-tissue dissection and helps preserve bone and periosteum.
Reproducible: The GraftPro® graft prep system simplifies graft preparation; the tapered graft and adjustable ACL TightRope II buttons facilitate graft passing, fine tuning of graft depth, and graft tensioning from the femoral and tibial sides.

Hamstring Autograft ACL Reconstruction

For primary and revision ligament repairs and reconstruction procedures, a variety of tendon allografts—including a wide portfolio of presutured tendons—are available. &nbsp;Allograft tendons provide many benefits compared to autograft tendons in reconstructive procedures, including less donor-site morbidity,1,2 fewer incisions, shorter operative time,1,2 larger and predictable graft sizes,2 and decreased postoperative pain and stiffness.2&nbsp;
 
Choose from sterile or aseptically processed tendons. Sterile tendons from our tissue bank alliance partners are rendered sterile without biomechanical or biochemical changes to the tissue.&nbsp;
 
Presutured constructs are an off-the-shelf solution requiring minimal preparation time while providing surgeons with a high-quality, consistent, sterile, and strong allograft tendon.&nbsp;

Allograft ACL Reconstruction

Harnessing the power of biologics to provide all necessary components of healing, the BioACL™ technique uses the patient’s own bone collected using the GraftNet™ device and mixed with autologous bioactive fluid.&nbsp;
Using the Angel® system or Arthrex ACP® double-syringe system, concentrated platelet-rich plasma (cPRP) is obtained from bone marrow aspirate (BMA) or whole blood. The autologous mixture is then delivered into the bone tunnels created during an ACL reconstruction. In conjunction with the QuadLink™ technique, the BioACL technique provides the ultimate anatomic, minimally invasive, and reproducible approach for biologically augmented ACL reconstructions.

BioACL™ Technique

ACL Reconstruction

A technique gaining popularity, PCL repair is generally indicated for bony avulsions that can occur on either the femur or tibia.&nbsp;
PCL injuries can happen during sports-related activities or high-velocity, traumatic accidents. Applications for operative treatment of PCL tears include acute injuries, tears in active young patients, and either isolated grade 3 tears or a combined injury, such as grade 2 tears with posterolateral corner instability.
PCL tears can be treated with innovative, minimally invasive procedures using the PCL Repair TightRope® implant and FiberRing™ sutures.

Posterior Cruciate Ligament (PCL) Repair 

PCL Repair 

PCL injuries occur during sports-related activities or high-velocity, traumatic accidents. Indications for operative treatment of PCL tears include acute injuries, active young patients, and either isolated grade 3 tears or combined injuries, such as a grade 2 injury with posterolateral corner instability. 

Arthrex developed several techniques for isolated PCL injuries—including PCL inlay reconstruction, double-bundle PCL reconstruction, and the transtibial PCL RetroConstruction™ procedure—that can be combined with multiligament or posterolateral corner reconstruction.&nbsp;
Additionally, a comprehensive line of PCL reconstruction instrumentation is available for a variety of PCL reconstruction techniques, as well as autografts and allografts and single- or double-bundle options.

Posterior Cruciate Ligament (PCL) Reconstruction

PCL Reconstruction

Relatively uncommon knee injuries, tibial spine avulsion fractures typically occur in children and adolescents.1 Despite the low incidence of tibial spine avulsion fractures, they deserve ample attention to ensure knee function and stability are correctly restored.
Innovative FiberRing™ sutures provide a simple and reproducible technique for securing the distal remnant to achieve anatomic reduction. The ACL Repair TightRope® implant offers titratable knotless fixation to ensure ACL length is appropriately restored and maintained.
Finally, the ACL InternalBrace™ ligament augmentation button accommodates the InternalBrace technique to help prevent excess range of motion during the healing phase and potentially reduce the chances of secondary injury.2,3
