Graft Reorientation and Lateral Extra-articular Tenodesis in Revision Surgery for Persistent Rotational Instability of a Verticalized Anterior Cruciate Ligament Graft.

Persistent rotational instability after anterior cruciate ligament reconstruction is a relatively common postoperative complication, typically associated with graft verticalization due to improper femoral tunnel placement, especially with classic transtibial femoral tunnel techniques. This article describes a technique designed to reorient a verticalized anterior cruciate ligament graft at its femoral insertion to a more anatomic position in the coronal and sagittal planes, aiming to restore knee stability without the need for a complete revision operation. Additionally, a lateral extra-articular tenodesis with fascia lata is added to reinforce rotational stability.

The Proportion of Meniscus Tears Considered Repairable, and Thus Repaired, Increased During a Single Surgeon's Practice of 20 Years.

Purpose: The purpose of this study was to evaluate practice patterns of a single surgeon with respect to meniscectomy and meniscal repair over a 20-year period at a single institution.

Methods: A cross-sectional descriptive study was carried out by reviewing the surgical data from the past 20 years (2002-2021) of patients who underwent arthroscopic primary meniscal surgery. Age, sex, knee and meniscus affected, morphology of the meniscal tear, meniscal radial location, location on the axial plane, tissue quality, and associated injuries were recorded.

Anterior Cruciate Ligament Revision Surgery Associated to Lateral Collateral and Anterolateral Ligaments Reconstruction With Single Achilles Tendon Allograft and Single Femoral Tunnel.

Lateral collateral ligament (LC) injuries that go unnoticed when associated with an anterior cruciate ligament (ACL) tear can increase stress forces on the ACL graft causing its failure. Furthermore, it is a main stabilizer to varus stress and external rotation. On the other hand, the reinforcement of anterolateral structures during ACL reconstruction has regained popularity in recent years, because evidence has shown that it increases the control of rotational laxity and decreases ACL graft failures, especially in revision surgery.

Anterior Cruciate Ligament Reconstruction Using Combined Graft of Hamstring and Fascia Lata With Extra-articular Tenodesis. A Technique in Case of Insufficient Hamstrings.

A technique for augmentation of the anterior cruciate ligament (ACL) with hamstring graft and lateral extra-articular tenodesis is presented. The patient is positioned supine with the knee flexed 90°. First, intra-articular injuries are addressed arthroscopically, and then autologous hamstring tendons are harvested and measured; the present technique is a resource for cases with a very small graft diameter (less than 8 mm), due to thin tendons or to tendon breakage, even after tripling the hamstring graft, which is prepared using a facia lata strip long enough to fit the lengths of the femoral tunnel, the anterior cruciate ligament graft, and the tibial tunnel.

Physeal Sparing Anterior Cruciate Ligament Reconstruction in Skeletally Immature Patients Bridging the Tibial Physis With Two Divergent Tunnels.

A technique for anterior cruciate ligament (ACL) reconstruction in patients with open physis is presented. The patient is positioned supine with the knee flexed 90°. After intraarticular injuries are addressed, an autologous hamstring graft is harvested and prepared using a suspension device attached in its expansion device.

The Finochietto Sign as a Pathognomonic Finding of Ramp Lesion of the Medial Meniscus.

Ramp lesions are considered hidden injuries of the medial meniscus and are very difficult to diagnose. The Finochietto jump sign is a very specific finding that could be considered pathognomonic regarding ramp lesions. This sign consists of a sudden jerk that appears when the free edge of the posterior horn of the medial meniscus is dislocated anteriorly due to the medial condyle interposition when an anterior drawer test is performed on a knee with a ramp lesion, especially when it is associated with an anterior cruciate ligament tear.

Obesity and Meniscal Transplant Failure: A Retrospective Cohort Study.

The purpose of this study was to analyze the effect of obesity and other clinical factors on the outcome of meniscal allograft transplantation (MAT) with transosseous fixation. A retrospective cohort study was performed on patients who underwent a MAT between 2002 and 2017. All the participants had a minimum follow-up period of 24 months.

Non anatomic reinsertion after amputation of the anterior horn of the lateral meniscus.

Anatomical reinsertion is the optimal treatment for meniscal root injuries. However, in chronic settings, tissue fraying of the meniscal root may impede it. This study describes a salvage technical procedure performed in 3 cases of chronic anterior root avulsion of the lateral meniscus with profuse tissue degeneration in which remnant debridement resulted in amputation of the root.

One-Third of Meniscal Tears Are Repairable: An Epidemiological Study Evaluating Meniscal Tear Patterns in Stable and Unstable Knees.

Purpose: To analyze, in a long series of patients with knee injuries, the meniscal tear patterns in both stable and unstable knees to ascertain the exact proportion of such injuries that could have been repaired.

Methods: A descriptive cross-sectional study was undertaken by reviewing the clinical reports of arthroscopic knee operations carried out in 1 hospital. A total of 2,066 consecutive patients were included in the study.

Arthroscopic Treatment of Concurrent Avulsion Fracture of Anterior and Posterior Cruciate Ligament with Suspension Device.

Introduction: Simultaneous avulsion fractures of the insertion of both cruciate ligaments of the knee are extremely uncommon lesions and their treatment remains difficult. The purpose of this paper is to show an arthroscopic repair technique of simultaneous tibial avulsion fracture of both cruciate ligaments of the knee such by using an adjustable length suspension device.

Case Report: A 25-year-oldmale patient was treated by arthroscopic reduction and fixation of both bony avulsion of cruciate ligaments of the knee with a sliding and adjustable length suspension device (ZipTight, Biomet, Warsaw, IN, USA).

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

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.

"Over the Top" Augmentation for Partial Anterior Cruciate Ligament Tears Using Suspension Device for Tibial Fixation.

A technique for augmentation of the partial anterior cruciate ligament is presented. The patient is positioned supine with the knee flexed 90°. After addressing intra-articular injuries, the autologous semitendinosus tendon is harvested and measured in a doubled manner; after that, the tibial tunnel is performed in the outside-in direction, of the same diameter of the doubled graft.

Associated Reconstruction of Anterior Cruciate and Anterolateral Ligaments With Single Asymmetric Hamstring Tendons Graft.

The anterior cruciate ligament (ACL) rupture is a common disease that accounts for 250,000 cases/year in the United States. The anterolateral ligament (ALL) has been suggested to be an important restraint for rotational instability, and its reconstruction provides a reinforcement to the ACL reconstruction in this aspect, especially in high-demand athletes and in knees with high-grade pivot shift. Different techniques for associated ACL and ALL reconstruction have been described, but the ideal technique remains unclear.

Transosseous Posterior Meniscal Root Reinsertion Using Knotless Anchor for Tibial Fixation.

A technique for posterior meniscal root reinsertion is presented. With the arthroscope in the central transtendinous portal for a better view, a 5-mm transtibial tunnel is created with the aid of an anterior cruciate ligament guide open to 45°. A suture device, which consists of a long needle with an eyelet on its tip, is introduced through the tunnel with a suture thread inserted through the eyelet, while the meniscus is stabilized with a grasper inserted through the anterior portal.

Posterior Cruciate Ligament Reconstruction With Hamstring Tendons Using a Suspensory Device for Tibial Fixation and Interference Screw for Femoral Fixation.

A technique for posterior cruciate ligament reconstruction is presented. Autologous hamstring tendons are selected as a graft. An interference screw is used for femoral fixation.

Symptomatic Bilateral Torn Discoid Medial Meniscus Treated with Saucerization and Suture.

Discoid meniscus is an anatomical congenital anomaly more often found in the lateral meniscus. A discoid medial meniscus is a very rare anomaly, and even more rare is to diagnose a bilateral discoid medial meniscus although the real prevalence of this situation is unknown because not all the discoid medial menisci are symptomatic and if the contralateral knee is not symptomatic then it is not usually studied. The standard treatment of this kind of pathology is partial meniscectomy.
