The 8-Strand Hamstring Autograft in Anterior Cruciate Ligament Reconstruction.

ABSTRACT: Growing participation in youth athletics has resulted in increased numbers of anterior cruciate ligament (ACL) injuries in skeletally immature patients. Use of autogenous graft material has been associated with improved graft survival. However, pediatric patients sometimes possess hamstring tendons that produce smaller-diameter grafts than those prepared with adult autogenous materials. Smaller-diameter grafts may predispose younger patients to graft failure. We describe a technique that increases the diameter of the ACL construct through the use of an 8-strand autologous hamstring tendon graft. The 8-strand ACL autograft is commonly used in all-inside ACL reconstruction surgery.

Five-strand hamstring autograft for anterior cruciate ligament reconstruction.

Project description:Four-strand hamstring autograft is a common choice for anterior cruciate ligament reconstruction. A potential disadvantage of hamstring autograft for anterior cruciate ligament reconstruction is the inherent variability in graft diameter. Multiple studies have shown increased revision rates when using an undersized hamstring graft. Using an EndoButton (Smith & Nephew, Andover, MA) for femoral tunnel fixation, we convert a standard quadrupled hamstring graft into a 5-strand graft by creating 3 equal strands of the typically larger semitendinosus combined with a double-stranded gracilis. This technique may help alleviate some surgeon reluctance to use a hamstring graft by providing an intraoperative "bailout" option for an unexpectedly small tendon. On the basis of current data, increasing the diameter of the graft in these situations may decrease revision rates.

A Bone-Hamstring Autograft for Arthroscopic Anterior Cruciate Ligament Reconstruction.

Project description:We describe a bone-hamstring autograft for anterior cruciate ligament reconstruction (ACLR). The semitendinosus and gracilis tendons are harvested using an open tendon stripper, keeping these distal tibial insertions intact. The bone-hamstring autograft is harvested using an oscillating saw. This modified autograft has the following advantages: (1) It possesses the potential for healing with the femur owing to its bone plug; (2) it is perfectly suited for various single-bundle reconstruction methods including oval-tunnel and rectangular-tunnel ACLR, as well as other flat ACLR methods; and (3) it is an attractive option for both primary ACLR and revision ACLR owing to its unique characteristics.

Anterior Cruciate Ligament Reconstruction Using Hamstring Tendon Autograft With Preserved Insertions.

Project description:We present a technique for anterior cruciate ligament (ACL) reconstruction using hamstring tendon autograft with preserved tibial insertions. The tendons, harvested with an open-ended tendon stripper while their tibial insertions are preserved, are looped around to prepare a quadrupled graft. The femoral tunnel is drilled independently through a transportal technique, whereas the tibial tunnel is drilled in a standard manner. The length of the quadrupled graft and loop of the RetroButton is adjusted so that it matches the calculated length of both tunnels and the intra-articular part of the proposed ACL graft. After the RetroButton is flipped, the graft is manually tensioned with maximal stretch on the free end, which is then sutured to the other end with preserved insertions. We propose that preserving the insertions is more biological and may provide better proprioception. The technique eliminates the need for a tibial-side fixation device, thus reducing the cost of surgery. Furthermore, tibial-side fixation of the free graft is the weakest link in the overall stiffness of the reconstructed ACL, and this technique circumvents this problem. Postoperative mechanical stability and functional outcome with this technique need to be explored and compared with those of ACL reconstruction using free hamstring autograft.

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.

Biologic and Mechanical Augmentation in Anterior Cruciate Ligament Reconstruction: Fibrin Clot Augmentation of 5-Strand Hamstring Autograft.

Project description:Hamstring autografts in anterior cruciate ligament reconstruction have an excellent clinical track record, but some patients have hamstring tendons that yield grafts of smaller diameter, which has been shown to be a significant risk factor for worse outcomes and graft failure. Some authors have advocated augmentation with allograft in these patients. Tripling the semitendinosus yields a completely autogenous 5-strand graft with a larger diameter but still of sufficient length. In addition, imaging studies still show signal heterogeneity within grafts, even autografts, after the healing process, which correlates with worse biomechanical properties. Recent animal studies have shown improved incorporation and better remodeling of soft tissue grafts with the use of an endogenous fibrin clot. We present our technique of biologic and mechanical augmentation of hamstring autografts with fibrin clot and a 5-strand graft.

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.

Bone-Tendon-Autograft Anterior Cruciate Ligament Reconstruction: A New Anterior Cruciate Ligament Graft Option.

Project description:The bone-tendon-bone (BTB) autograft is widely used for anterior cruciate ligament (ACL) reconstruction. However, the primary disadvantages of this technique include postoperative kneeling pain, the risk of perioperative patellar fracture, and graft-tunnel mismatch. Therefore, a single bone plug technique for ACL reconstructions was developed to mitigate the disadvantages of the BTB technique. To differentiate this graft, we have coined the term BTA, for bone-tendon-autograft. The middle third of the patellar tendon is used with a typical width of 10 to 11 mm. A standard tibial tubercle bone plug is harvested. The length of the patellar tendon and graft construct is then measured. If the tendon is >45 mm and the construct at least 70 mm, then we proceed with the BTA technique. At the inferior pole of the patella, electrocautery is used to harvest the tendon from the patella. The advantages of this technique include faster graft harvest and preparation. Obviating the patellar bone plug harvest should eliminate the risk of perioperative patellar fracture and theoretically will mitigate donor site morbidity and kneeling pain, 2 of the most commonly cited complications of the use of BTB autografts for ACL reconstruction. In conclusion, the BTA technique is a reliable technique for ACL reconstruction.

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 Braid Graft Technique for Anterior Cruciate Ligament Reconstruction.

Project description: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.

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.
