Associated Anterior Cruciate Ligament and Fibular Collateral Ligament Reconstruction With Single Femoral Tunnel and Asymmetric Hamstring Tendon Graft.

ABSTRACT: A technique for associated anterior cruciate ligament and fibular collateral ligament reconstruction is shown, using a single hamstring tendon graft, which is prepared asymmetrically, leaving one-third of the length with a single diameter and two-thirds with a double diameter. A single femoral tunnel is created, using an interference screw for fixation and isolation of the grafts. A suspension device is used for tibial fixation, allowing for length adjustment according to the graft's length. The objective of this Technical Note is to provide the orthopaedic surgeon with a resource for anterior cruciate ligament and fibular collateral ligament reconstruction even with short grafts, saving bone stock and avoiding the need for allografts.

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.

Combined Anterior Cruciate Ligament and Posterolateral Corner Reconstruction by Hamstring Tendon Autografts Through a Single Femoral Tunnel by Graft-to-Graft Suspension and Fixation.

Project description:An untreated posterolateral corner (PLC) injury in patients with a torn anterior cruciate ligament (ACL) may be a leading cause of ACL reconstruction failure. Combined ACL and PLC reconstruction is discussed in few studies in the literature. Femoral tunnel intersection in combined reconstruction has been reported to be high. Short grafts may render combined reconstruction undoable. This Technical Note describes a technique that allows a combined ACL and PLC reconstruction. The ACL graft is a 4-stranded hamstring tendon graft from 1 limb. The PLC graft is a doubled semitendinosus tendon graft from the contralateral side. One femoral tunnel is used connecting the femoral attachment of the PLC on the lateral wall of the lateral femoral condyle to the anatomic femoral ACL footprint on the medial wall of the lateral femoral condyle. The PLC graft is suspended on the ACL graft to be anchored on the cortex of the lateral femoral condyle with added fixation by an interference screw (Arthrex, Naples, FL). The PLC graft limbs are used for open reconstruction of the fibular collateral ligament, popliteus tendon, and popliteofibular ligament. This Technical Note describes a technique of combined ACL and PLC reconstruction with hamstring tendon autografts through a single femoral tunnel using graft-to-graft suspension and fixation.

Anatomic Double-Bundle Anterior Cruciate Ligament Reconstruction with Hamstring Tendon Autograft through Single Femoral Tunnel and Single Branched Tibial Tunnel.

Project description:Conventional single-bundle anterior cruciate ligament (ACL) reconstruction cannot improve the rotational stability of the knee. Traditional double-bundle ACL reconstruction requires is demanding, complex, time- and implant consuming, and associated with a high incidence of complications. Double-bundle ACL reconstruction using a free quadriceps tendon autograft through 3 independent tunnels provides some advantage, but the antegrade graft passage, tibial tunnel confluence, and graft site morbidity represent disadvantages. This Technical Note describes a modification of double-bundle ACL reconstruction using the hamstring tendon autograft through a single branched tibial tunnel and a single femoral tunnel using 2 interference screws (Arthrex, Naples, FL). The gracilis tendon autograft is passed through tibial tunnel stem to the posterolateral tibial tunnel branch to the posterolateral position in the femoral tunnel. The semitendinosus tendon autograft is passed through the tibial tunnel stem to the anteromedial tibial tunnel branch to the anteromedial position in the femoral tunnel. Both grafts are fixed by 2 interference screws: 1 at the femoral tunnel and 1 at the tibial tunnel stem with the knee at 20° flexion.

Anatomical Arthroscopic Anterior Talofibular Ligament and Calcaneofibular Ligament Reconstruction Using an Autogenic Hamstring Tendon: Safe Creation of Anatomical Fibular Tunnel.

Project description:Ankle sprains are the most common lower extremity injuries associated with sports activity. Although ligament repair techniques are popular, reconstruction methods using free tendons are considered when the ligament remnant is insufficiently strong, when high-demand athletes sustain repeat ankle sprains, or in revision cases after repair. Recently, some arthroscopic reconstruction techniques have been reported. The distal fibular end is thin; therefore, surgeons must be careful while drilling the fibular tunnel. This report indicates the safe creation method of an anatomical fibular tunnel during anatomical arthroscopic reconstruction of the anterior talofibular ligament and calcaneofibular ligament. This also provides a stronger reconstruction using a 2-strand tendon graft for the anterior talofibular ligament substitute, which is thought to have less risk for postoperative graft failure.

Fatigue Behavior of Nitinol Anterior Cruciate Ligament Graft and Inappropriate Femoral Tunnel Placement: Single-Stage Revision Anterior Cruciate Ligament Reconstruction Surgery.

Project description:Anterior cruciate ligament (ACL) injury is the most common ligament injury in the knee, and progressive instability and disability may develop in a significant number of patients. The incidence of ACL reconstruction is rapidly increasing, as is the number of failures. Although ACL reconstruction is a common procedure, less than satisfactory outcomes have been reported to occur in up to 25% of patients. The reasons for clinical failure after ACL reconstruction are numerous but can be broadly separated into 3 categories: technical, biological, and mechanical failures. It is generally thought that poor tunnel positioning (especially the femoral tunnel) is the most common technical error. Revision ACL reconstruction can be performed in 1 or 2 stages. The decision to perform a multistage approach is based on the position and size of the original tunnels. The varied success rates and associated advantages and disadvantages of each method have resulted in controversy as to the best treatment for revision ACL surgery. We describe our preferred operative technique to remove a fractured nitinol synthetic ACL graft and manage single-stage revision ACL reconstruction without bone grafting.

Anterior Cruciate Ligament Reconstruction with 4-Strand Hamstring Tendon Construct May be Biomechanically Superior to 5-Strand Hamstring Tendon Construct When Using Femoral Suspensory Fixation

Project description:Purpose To compare stiffness, strain, and load to failure of 4- versus 5-strand hamstring anterior cruciate ligament reconstruction human tendon allografts with femoral suspensory and tibial interference screw fixation Methods Allograft hamstring tendons were used to create 10 four-strand (4S) and 10 five-strand (5S) grafts. Grafts were fixed to a uniaxial electromechanical load system via a femoral cortical suspensory button and a bioabsorbable interference screw in bone analogue. Grafts were cycled from 100 Newtons (N) to 250 N for 1,000 repetitions at 0.5 hertz before load to failure testing. Cyclic displacement was defined as the difference in graft length from the first 20 to 30 cycles compared with the last 10 cycles. Trials were recorded on a high-definition camera to allow for digital image correlation analysis. Results Cyclic displacement more than 1,000 cycles was significantly lower in the 4S compared with the 5S group (0.87 vs 1.11 mm, P = .037). Digital image correlation analysis confirmed that the fifth strand elongated more than the other 4 strands in the 5S constructs (6.1% vs 3.9%, P = .032). Load to failure was greater in the 4S compared with the 5S group but not statistically significant (762 vs 707 N, P = .35). Stiffness was similar between constructs (138.5 vs 138.3 N/mm, P = .96) Conclusions Compared with cyclically loaded 4S hamstring grafts, the 5S grafts had significantly increased displacement over time in a model of femoral suspensory and tibial interference screw fixation. Clinical Relevance Anterior cruciate ligament reconstruction with hamstring tendon autograft is a commonly performed surgery with excellent outcomes. It has been shown that graft diameter influences these outcomes. As surgeons use larger grafts, it is important to investigate how these constructs may affect the outcomes of surgery.

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.

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.
