Combined Anterior Cruciate Ligament and Medial Collateral Ligament Reconstruction Using a Single Achilles Tendon Allograft.

ABSTRACT: Approaches to management of combined anterior cruciate ligament (ACL) and high-grade medial collateral ligament (MCL) injuries remain controversial. Some studies suggest that with grade III MCL injuries, patients may benefit from concurrent MCL reconstruction to restore stability and prevent increased stress on the ACL graft. We present a technique for simultaneous ACL/MCL reconstructions using a single Achilles tendon allograft.

Achilles Tendon Allograft Preparation Technique for Anterior Cruciate Ligament Reconstruction: A Technical Note.

Project description:Several factors associated with graft preparation for the surgery of the anterior cruciate ligament (ACL) like the wrong thawed, prophylaxis, bone cuts, excessive bone removal as well as positioning problems like a tunnels-graft mismatch, insufficient harvesting of the donor's tendon, size graft limitations (length and diameter), uncontrolled rotation of graft in their longitudinal axis, over or under tensioned graft, fixation mistakes, bone defects, secondary arthrofibrosis or morbidity of the donor site, and others factors importantly affect the outcomes of the ACL surgery. In this sense, the Achilles tendon Allograft is an advantageous technique where many of the previous limitation factors described can be controlled during an appropriate preparation. However, to obtain the maximum potentialities of the graft a detailed knowledge of the preparation is required. Hence, we aimed to describe how to prepare the Achilles tendon Allograft to control the graft's length and diameter, bone removal, and fixation requirements.

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 Reconstruction of the Medial Collateral Ligament and Anterior Cruciate Ligament Using Ipsilateral Quadriceps Tendon-Bone and Bone-Patellar Tendon-Bone Autografts.

Project description:The exclusive autograft choice for medial collateral ligament (MCL) reconstruction that has been described until today is the semitendinosus tendon. However, this has some potential disadvantages in a knee with combined MCL-anterior cruciate ligament (ACL) injury, including weakening of the hamstring's anterior restraining action in an already ACL-injured knee and nonanatomic distal MCL graft insertion when leaving the semitendinosus insertion intact at the pes anserinus during reconstruction. Moreover, because some surgeons prefer to use the hamstring for autologous ACL reconstruction, the contralateral uninjured knee hamstring needs to be harvested as a graft source for the MCL reconstruction if autografts and not allografts are the surgeons' preference. We describe a technique for performing combined reconstruction of the MCL and ACL using ipsilateral quadriceps tendon-bone and bone-patellar tendon-bone autografts. This technique of MCL reconstruction spares the hamstring tendons and benefits from the advantage provided by bone-to-bone healing on the femur with distal and proximal MCL tibial fixation that closely reproduces the native MCL tibia insertion.

Medial Patellofemoral Ligament Reconstruction Using Achilles Tendon Allograft With Bone Block.

Project description:Recurrent patellar instability is a common problem and often leads to a tear of the medial patellofemoral ligament. Multiple reconstruction techniques for the medial patellofemoral ligament (MPFL) exist. This Technical Note presents a technique for performing MPFL reconstruction using Achilles tendon allograft with a bone block. The advantages of this technique include (1) bone-to-bone healing in femoral tunnel; (2) docking the bone block in the femoral tunnel obviates the knee for calculating graft and tunnel length; (3) fixing the femoral side before the patellar side allows graft tensioning under direct visualization and avoids over-constraint; (4) the fanned portion of the Achilles tendon allows broad-based MPFL footprint coverage on the medial patellar ridge; and (5) it avoids the need for bone tunnel drilling in the patella, reducing the risk to penetration of the drill holes into the articular cartilage surface as well as the risk for patellar fracture.

Combined Posterior Cruciate Ligament and Superficial Medial Collateral Ligament Knee Reconstruction: Avoiding Tunnel Convergence.

Project description:Combined posterior cruciate ligament (PCL) and medial collateral ligament (MCL) injuries represent a complex pathology that requires a thorough clinical and radiographic examination to diagnose and identify all injured structures. Anatomic reconstruction of the injured ligaments is recommended, including double-bundle PCL reconstruction and superficial MCL augmentation. In the setting of this complex reconstruction, several technical aspects require consideration and preoperative planning, including the risk of femoral tunnel convergence on the medial aspect of the femoral condyle. This article details our technique for combined anatomic double-bundle PCL reconstruction and superficial MCL augmentation to avoid tunnel convergence. Level I (knee); level II (PCL).

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.

Combined Double-Bundle Anterior Cruciate Ligament Reconstruction and Anterior Cruciate Ligament-Mimicking Anterolateral Structure Reconstruction.

Project description:The outcomes of double-bundle anterior cruciate ligament (ACL) reconstruction leave room for improvement. We hope to augment double-bundle ACL reconstruction with the reconstruction of an ACL-mimicking anterolateral structure (ALS). Thus, we would like to introduce a combined double-bundle ACL reconstruction and ACL-mimicking ALS reconstruction technique. The main indication for this technique is ACL injury with a high degree of pivot shift test, general laxity, or near critical value of the posterior tibial slope. The main steps in this technique include preparation of an isolated graft for the anteromedial bundle of the ACL and a combined graft for the posterolateral bundle of the ACL and ALS, creation of three tibial tunnels and two femoral tunnels, graft placement, and final graft fixation at an adjustable loop. We have obtained promising clinical outcomes with this technique and consider that this report will provide new options in ACL reconstruction.

Anteromedial Portal Anterior Cruciate Ligament Reconstruction With Tibialis Anterior Allograft.

Project description:In an effort to better restore normal joint function and kinematics, recent emphasis has been placed on surgical techniques that provide a more anatomic reconstruction of the anterior cruciate ligament (ACL). With femoral tunnel placement shown to play a vital role in the biomechanics, stability, and clinical outcomes after ACL reconstruction, approaches that better approximate the ACL's native femoral origin have been adopted. The independent anteromedial portal technique is thought to better position the femoral tunnel within the native ACL footprint and leave the graft more posteroinferior on the wall of the lateral femoral condyle than the more traditional transtibial approach. This article outlines the surgical technique for an anteromedial portal ACL reconstruction with a tibialis anterior allograft fixed with the Mitek Femoral and Tibial Intrafix sheath and screw system (DePuy Synthes, Raynham, MA).

Combined Anterior Cruciate Ligament and Anterolateral Ligament Reconstruction.

Project description:Despite technologic advances in the surgical technique for anterior cruciate ligament (ACL) reconstruction, some patients continue to have rotational instability postoperatively. Recently, authors have reported the anatomic and functional characteristics of the anterolateral ligament (ALL), a structure that originates near the lateral epicondyle on the femur and inserts on the tibia between the Gerdy tubercle and the fibular head. Recent biomechanical studies have shown the ALL is an important stabilizer against anterolateral tibial rotation, and its reconstruction has shown excellent initial clinical results. Several techniques have been developed to try to anatomically address this structure in the setting of an ACL reconstruction. This article details a simple anatomic technique to reconstruct the ACL and the ALL of the knee using hamstring tendon autograft and maintaining the semitendinosus insertion.
