Hamstring Braid Graft Technique for Anterior Cruciate Ligament Reconstruction.

ABSTRACT: Hamstring autograft is one of the most used grafts for anterior cruciate ligament (ACL) reconstruction, although there are several graft preparation techniques. It is extremely difficult to mimic the biomechanical properties of the native ACL; thus, it is important to achieve a proper graft configuration, diameter, and length. To avoid reruptures, an optimal and reproducible hamstring autograft is desired. Hamstring autograft has been traditionally devalued when compared with other options such as bone-patellar tendon-bone autograft. The purpose of this Technical Note is to describe in detail a hamstring braid graft configuration that could potentially overcome the past disadvantages of ACL reconstruction.

Four-Strand Hamstring Diamond Braid Technique for Anterior Cruciate Ligament Reconstruction.

Project description:Several factors affect the success of an anterior cruciate ligament reconstruction, including graft origin, type, and morphology. Hamstring and bone-patellar tendon-bone autografts are the most widely used, and there are many different techniques of graft preparation with each. In this Technical Note and accompanying video, a 4-strand hamstring autograft technique is described that uses a simple diamond-type braid to produce a more ovoid morphology with increased cross-sectional area. Increased graft diameters have been associated with higher success rates and more positive long-term outcomes. Therefore, this braiding construct may provide additional tensile strength with increased resistance to failure than grafts that are otherwise undersized using conventional techniques.

Graft Preparation Technique to Optimize Hamstring Graft Diameter for Anterior Cruciate Ligament Reconstruction.

Project description:Hamstring autografts are frequently used for anterior cruciate ligament reconstruction. The inherent variability in graft diameter has been stated as a disadvantage in its use because the presence of smaller graft diameters has been correlated with increased risk of re-rupture. Several techniques have been described to address this concern. Modifications of the basic Graftlink technique allows for increased control over final graft diameter using a standard harvest of the semitendinosus tendon with or without the gracilis tendon, and results in a graft of adequate length and diameter in all patients with rigid cortical fixation on the femur and tibia.

Hamstring Graft Preparation Techniques for Anterior Cruciate Ligament Reconstruction.

Project description:Anterior cruciate ligament reconstruction is one of the most commonly performed procedures in orthopaedics, with more than 125,000 performed in the United States per year. There are several reconstruction graft choices that can be used to reconstruct the native anterior cruciate ligament, with autograft hamstring tendons being one of the most commonly used. Preparation of a hamstring autograft varies depending on patient characteristics and physician preference. The purpose of this Technical Note is to describe in detail different variants of hamstring graft preparation techniques that are commonly used in practice.

Hamstring Graft Biological Preparation for Anterior Cruciate Ligament Reconstruction.

Project description:The all-inside anterior cruciate ligament reconstruction (ACLR) success depends on biologic integration of the graft in the bone tunnel. Sutures wrapping the tendon in the bone tunnel may affect tendon-bone healing in shorter bone tunnels. To achieve better graft integration, we propose a variation of the graft link suture technique wherein the graft is linked chain-like to the femoral and tibial TightRope (Arthrex), which increases the tendon-bone contact area by eliminating sutures from the noose of the graft and thus may allow better graft integration.

Autogenous Hamstring-Bone Graft Preparation for Anterior Cruciate Ligament Reconstruction.

Project description:Despite the popularity of anterior cruciate ligament (ACL) reconstruction procedures, the ideal graft for reconstruction remains a matter of controversy. The ideal graft for ACL reconstruction should have histologic and biomechanical characteristics similar to those of the native ACL; should be quickly and fully incorporated within the bony tunnels; should maintain its viscoelastic properties for a long time; should have minimal donor-site morbidity; should be of sufficient length and diameter; should have minimal adverse effects on the extensor mechanism; should have no risk of rejection or disease transmission; and should be cost-effective and readily available. Synthetic grafts are not widely accepted because of their dangerous complications. The main sources of grafts for ACL reconstruction are allografts and autografts. Each type of graft has its own relative advantages and disadvantages. Allografts are not available in every country, besides being expensive, and there are many concerns regarding disease transmission. Autografts, particularly bone-patellar tendon-bone (BPTB), and hamstring tendon grafts have been the standard for ACL reconstruction. The main advantage of autogenous BPTB grafts is the direct bone-to-bone healing in the tunnel, whereas the main disadvantages of such grafts are related to donor-site morbidity, anterior knee pain, and extensor mechanism dysfunction. The popularity of autogenous hamstring tendon grafts for ACL reconstruction is increasing, but there are still concerns regarding the slow soft tissue-to-bone healing, with delayed healing and incorporation of the graft. We describe a technique for ACL reconstruction with autogenous hamstring-bone graft, aiming to produce a type of graft that combines the main advantages of BPTB and hamstring grafts, with avoidance of the main disadvantages of these 2 most commonly used graft types in ACL reconstruction.

The 5-strand hamstring graft in anterior cruciate ligament reconstruction.

Project description:The use of anterior cruciate ligament reconstruction in the pediatric and adolescent population has been increasing in recent years. Autograft hamstring graft is favored in this population, but these patients often have smaller hamstring tendons that yield smaller final graft constructs. These smaller grafts are associated with an increased need for revision surgery. We describe a technique for obtaining a larger-diameter anterior cruciate ligament graft construct from autologous hamstring graft without allograft supplementation.

Revision Anterior Cruciate Ligament Reconstruction: Tibial Tunnel-First Graft-Sizing Technique.

Project description:Revision anterior cruciate ligament reconstruction (R-ACLR) has become more common as the number of failed primary ACLRs increase. Although increasingly common, R-ACLR has a greater failure rate than a primary reconstruction. Technical errors, particularly in tunnel placement, account for a large proportion of graft failure in R-ACLR as well as re-revision cases. Tunnel placement and trajectory is particularly important in R-ACLR and becomes more challenging with each additional revision attempt. This is in part because any tunnels created for revision may converge with formerly drilled tunnels or face interference hardware creating, complicating proper graft fixation. While there are many approaches to revision ACL surgery, our technique describes a simple, tibial tunnel-first graft-sizing method initially reaming tunnels with very small diameters and sequentially working your way up to more anatomic diameters.

Tibial inlay technique using hamstring graft for posterior cruciate ligament reconstruction and remnant revision.

Project description:The posterior tibial inlay technique is currently accepted as a standard operation for the posterior cruciate ligament-deficient knee. The classical technique requires a graft construct consisting of a bony part to be fitted into the posterior tibial socket. When an autogenous source is chosen, morbidity at the donor site generated by obtaining the graft with a bony part (e.g., bone-patellar tendon-bone or quadriceps tendon-bone) can be more serious than when obtaining the soft-tissue graft (e.g., hamstring). This study describes an alternative use of soft-tissue graft anchored in a bone socket at the posterior tibial margin by a transfixing cancellous screw. The graft is secured on top by a "bone washer" harvested from this bone socket to provide biological bone-tendon-bone healing. The posterior cruciate ligament remnant with integral fibers at the femur can have its tibial part revised, tensioned, and reattached concomitantly. This additional procedure is deemed to enhance joint stability and promote graft healing.

Internal Suture Augmentation Technique to Protect the Anterior Cruciate Ligament Reconstruction Graft.

Project description:The anterior cruciate ligament suture augmentation technique is a method to augment anterior cruciate ligament reconstruction (ACLR) with autologous hamstring tendons using a braided ultrahigh-molecular weight polyester or polyethylene suture or suture tape and fixed on both the femoral and tibial sides independent of the graft to act as a backup or secondary stabilizer until complete integration and ligamentization of the graft take place. The technique is proposed to allow early rehabilitation and return to sports after ACLR and may be advantageous in patients with a high body mass index and in cases with small grafts (7 or 7.5 mm in diameter). In such situations the technique is supposed to decrease the risk of reinjury, as well as the degree of postoperative lengthening or stretching of the graft, in the early postoperative avascular phase. We describe graft preparation with the internal suture augmentation technique in arthroscopic ACLR using a cortical button system on the femoral side and a Bio-Interference Screw (Arthrex, Naples, FL) on the tibial side.
