Inferior Medial Geniculate Artery Branch as an Anatomical Landmark for Hamstring Harvest During Anterior Cruciate Ligament Reconstruction.

ABSTRACT: Graft harvesting is often a challenging step of anterior cruciate ligament reconstructions. Accurate isolation of the hamstring tendons at the pes anserinus is crucial to successful graft harvesting. We describe a technique of using a branch of the inferior medial geniculate artery overlying the pes anserinus insertion as an anatomical landmark to localize the hamstring tendons for harvest. By using this vessel as an anatomical landmark, the incision length was decreased and the time required to harvest reduced. This is a highly reproducible technique and will be beneficial for soft tissue harvesting surgeons to ease hamstring graft harvesting.

Combined Anterior Cruciate Ligament, Medial Collateral Ligament, and Posterior Oblique Ligament Reconstruction Through Single Tibial Tunnel Using Hamstring Tendon Autografts.

Project description:Combined anterior cruciate ligament (ACL) and medial collateral ligament (MCL) injuries are the most common type of combined ligamentous injury of the knee. The optimal treatment for these combined injuries is controversial. Combined ACL and MCL-posterior oblique ligament (POL) reconstruction avoids late anteromedial rotatory instability and chronic valgus instability of the knee and decreases the increased stress on the ACL graft. Graft choice (hamstring tendon autograft, quadriceps bone-patellar tendon-bone autograft, or Achilles tendon allograft) and anatomic restoration of the medial and posteromedial corner of the knee are challenges of this combined reconstruction. This article describes a technique that allows combined ACL and MCL-POL reconstruction. The hamstring tendons from the contralateral limb are tripled and used as the ACL graft. The gracilis tendon from the ipsilateral limb is doubled and used as the MCL-POL graft. The semitendinosus tendon of the ipsilateral limb is preserved. After ACL reconstruction, the MCL-POL graft is suspended on the ACL graft at the distal end of the tibial tunnel and the graft limbs are used for open reconstruction of the MCL and POL. Three interference screws (Arthrex, Naples, FL) and 1 metal staple are used for graft fixation of this combined 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.

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.

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.

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 8-Strand Hamstring Autograft in Anterior Cruciate Ligament Reconstruction.

Project description: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.

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.

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.

Anatomical Single-Bundle Transtibial Anterior Cruciate Ligament Reconstruction.

Project description:Anatomical anterior cruciate ligament (ACL) reconstruction is a reasonable transition from isometric ACL reconstruction to obtain better clinical outcomes, and most authors believe that it can only be performed through the medial portal technique. However, in our clinical practice, we found that anatomical ACL reconstruction can be performed easily and accurately by creating a tibial tunnel, which is accomplished by setting the tibial tunnel with correct angulation to the sagittal plane and tibial axis. Hence, we introduce this special transtibial anatomical ACL reconstruction technique, in which the most critical step is the creation of a shallow tibial tunnel with a proximal projection to the anatomical location of the femoral tunnel. This technique is indicated for primary ACL reconstructions in skeletally mature patients. We believe this Technical Note will give a special view on anatomical ACL reconstruction.
