All-inside anterior cruciate ligament

PURPOSE: To investigate the effects of ramp lesion (RL) and its repair on knee instability in patients with anterior cruciate ligament (ACL) injury by quantitatively assessing anteroposterior and rotational knee instability before and after ACL reconstruction. METHODS: All primary double-bundle ACL reconstruction using hamstring autografts between 2016 and 2021 were evaluated retrospectively. Patients with RLs without other meniscal injuries were included in Group R, whereas those with isolated ACL injuries constituted Group C...

Medial meniscal ramp injury has gained the attention of orthopaedic surgeons in recent years. It consists of a tear of the peripheral insertion of the posterior horn of the medial meniscus. Its prevalence in anterior cruciate ligament reconstruction varies between 9% and 40% according to different studies. Ramp lesions cannot always be diagnosed using magnetic resonance imaging scans. To identify ramp lesions, the arthroscope should be introduced into the posteromedial compartment of the knee during the routine examination of the knee (Gillquist maneuver)...

In pediatric anterior cruciate ligament reconstruction, many factors should be considered: (1) risk of growth disturbance; (2) high risk of re-tear; (3) determination of the skeletal age, which is sometimes challenging; and (4) no single technique indicated for all patients. The choice of the technique mostly depends on the patients' age and growth potential. Whereas prepubescent patients can be safely treated with physeal sparing techniques (i.e., the Kocher-Micheli technique or its modifications), in postpubescent patients physeal respecting or adult-type reconstructions are generally indicated...

Lateral meniscus tears at the junction of the Wrisberg ligament and posterior horn are meniscocapsular injuries often seen with injury to the anterior cruciate ligament. Such lateral meniscus posterior horn lesions have been termed zip lesions. The lateral meniscus posterior horn is the major restraint for the pivot shift maneuver. Considering the morphology of condyles, lateral meniscus preservation and repair of unstable meniscocapsular posterior tear are needed to prevent future osteoarthritis. In this Technical Note, we aim to classify zip lesions of the posterior horn of the lateral meniscus...

PURPOSE: The aim of this study was to assess how gender might affect the clinical outcome and survival of meniscal allograft transplantation (MAT). METHODS: A total of 358 patients (23.2% women, 76.8% men) were treated with fresh-frozen nonirradiated allografts implantated arthroscopically using a single- or double-tunnel technique without bone plugs and peripheral suture to the capsule with 'all-inside' stitches. RESULTS: Patients were evaluated at baseline and 2-year follow-up with the Lysholm score, visual analogue scale (VAS) pain, the Knee Osteoarthritis Outcome Score (KOOS) subscales and Tegner score...

Numerous studies on meniscal tears have been published, a pathology that continues to evolve in terms of treatment and patient outcomes. As our understanding of anatomy and biomechanics improves, new entities have emerged. The lateral meniscus, especially its posterior attachment, tends to be overlooked due to its greater mobility compared to the medial meniscus. Evaluating the instability of the posterior horn poses a challenge, even during arthroscopy, therefore, it is crucial to understand the posterior menisco-synovial detachment lesions, which are indeed real and, to date, haven't received enough attention in the existing literature...

The anterior cruciate ligament (ACL) is the primary soft-tissue structure for anterior stabilization of the knee and is one of the most frequently injured structures. The incidence of ACL injuries in children and adolescents ranges from 92 to 151 per 100,000 person-years. The choice of surgical treatment for this population group is controversial, with a widespread concern that adult reconstruction techniques may damage the epiphyseal plate, compromise growth, or cause deformity. In this article, we describe a physeal-sparing, all-inside ACL reconstruction technique for skeletally immature patients...

INTRODUCTION: Ramp lesions, often associated with anterior cruciate ligament (ACL) injuries, exhibit a varied incidence rate of 9-42%, increasing with delayed ACL reconstruction. These lesions, resulting from abnormal tibial movements and semimembranosus muscle contraction, are challenging to diagnose due to their hidden nature in standard magnetic resonance imaging and arthroscopy procedures. CASE REPORT: This report examines the case of a ramp lesion in the context of a multi-ligament injured knee of a 34-year-old male...

BACKGROUND: There is ongoing debate about the best way to manage ramp lesions at the time of anterior cruciate ligament (ACL) reconstruction (ACLR). Type 3 lesions are not visible by the transnotch approach without superior debridement, making the management debate even more problematic. PURPOSE/HYPOTHESIS: The purpose of this study was to evaluate the rate of secondary surgical interventions according to the management method of a type 3 ramp lesion concomitant with primary ACLR...

OBJECTIVE: All-inside and standard techniques with 4-strand hamstrings graft have been widely used in anterior cruciate ligament (ACL) reconstruction. However, the graft diameter of less than 8 mm will significantly increase the rate of surgical failure, and the 6-strand graft can solve this problem. The purpose of this study is to compare all-inside ACL reconstruction using suspensory cortical button fixation on both tibia and femur with standard ACL reconstruction using suspensory femoral fixation and a bioabsorbable tibial interference screw with a 6-strand hamstring tendon autograft in postoperative clinical outcomes...

Anterior cruciate ligament reconstructions are often performed with associated procedures, most commonly for associated meniscal tears. The lateral meniscal root tear is a commonly associated injury, which increases rotational instability and results in altered tibiofemoral biomechanics. Lateral meniscectomy results in poorer functional and long-term outcomes, making repair vital. The position of the lateral root tear makes its repair technique complicated. Because of the proximity to vessels posteriorly, the all-inside technique is considered potentially unsafe, and current transtibial repair techniques fail to appose the body with the root remnant...

BACKGROUND: The aims of this study were to describe a lateral extra-articular tenodesis (LET) using no additional hardware and compare the tibiofemoral kinematics of anterior cruciate ligament (ACL) reconstruction augmented with either the LET or a standard anatomic anterolateral ligament (ALL) reconstruction using intra-tunnel fixation. METHODS: Ten cadaveric knees were mounted on a robotic testing system and underwent a kinematic assessment of anterior tibial translation and internal tibial rotation under a simulated pivot-shift in the following states: ACL-intact, ACL-sectioned, ACL-sectioned/anterolateral complex (ALC)-sectioned, ACL-reconstructed/ALC-sectioned, ACL-reconstructed/ALL-reconstructed, and ACL-reconstructed/LET...

PURPOSE: To compare clinical outcomes of the all-inside technique with the transtibial technique in anterior cruciate ligament reconstruction based on available literature on this topic. METHODS: According to the PRISMA checklist, we conducted a systematic search for randomized controlled trials and Cohort studies. Our comprehensive search encompassed PubMed, Embase, Cochrane Library, and Web of Science. We included RCTs and cohort studies that compared the two techniques with a minimal one-year follow-up...

Our main objective was to examine the curative effect of all inside technique and traditional technique in anterior cruciate ligament (ACL) reconstruction. In our retrospective study at the First People's Hospital of Jiashan County, we analyzed 88 participants with ACL injuries (50 males, 38 females, average age 27 years). They were randomly divided into two groups: traditional ACL reconstruction (42 participants) and all inside ACL reconstruction (46 participants). We measured and recorded the Visual Analog Scores (VAS), International Knee Documentation Committee (IKDC), Lysholm scores, operation time, graft diameter and length between the traditional technique group and all inside technique group...

PURPOSE: To (1) evaluate the clinical and radiographic outcomes of patients with primary anterior cruciate ligament reconstruction (ACLR) with type II posterior lateral meniscus root tear (PLMRT) repair and (2) identify whether increased anterior tibial subluxation of the lateral compartment (ATSLC) and steeper posterior tibial slope (PTS) are associated with sagittal lateral meniscal extrusion (LME). METHODS: Patients who underwent primary anatomic ACLR with concomitant type II PLMRTs using the all-inside side-to-side repair technique between November 2014 and September 2020 were identified...

PURPOSE: The aim of this study is to assess the dynamics of the tear site of meniscal ramp lesions, particularly considering knee flexion angles, and validate anchor fixation using an all-inside device. METHODS: Eight Thiel-embalmed paired cadaveric knees with their whole bodies were used in this study. The ramp lesions were created arthroscopically, and ramp lesion dynamics were evaluated by gradually extending the knee from 90° of knee flexion. Changes in the gap and step-off (0: no step-off; 1: cross-sectional overlap exists; and 2: tibial articular surface exposed) were evaluated at 90°, 60°, 30°, and 10° of knee flexion...

BACKGROUND: There is no clear consensus regarding the superiority of a combined anterior cruciate ligament reconstruction (ACLR) with anterolateral ligament reconstruction (ALLR) versus an isolated ACLR. In this study, we compared the postoperative stability profile, complications, and patient-reported outcomes of these procedures. METHODS: Twenty-one patients with an anterior cruciate ligament (ACL) tear who were either treated by an isolated all-inside ACLR (n = 21) or a combined all-inside ACLR and ALLR (n = 20) were included...

INTRODUCTION: Ipsilateral fracture of the femur and tibia, known by the moniker "floating knee," is a serious injury that primarily results from high-energy trauma. Up to 53% of patients with floating knee injuries have concurrent ligamentous injuries, with the anterior cruciate ligament (ACL) as the most commonly affected ligament. Approximately 10% of multi-ligament knee injuries consist of injuries to both the ACL and posterolateral corner (PLC); however, the literature reporting the management of this patient population is sparse, particularly, with a lack of consensus on the timing and protocol of surgical treatment...

BACKGROUND: Anterior Cruciate Ligament (ACL) injuries are common in the active population of the Armed Forces. Symptomatic instability prompts individuals to seek a cure or a sheltered appointment. Despite the increasing numbers of ACL reconstructions performed, the outcomes have not been so spectacular with only a meager percentage of our patients returning to preinjury levels of activity. With the premise that an all-inside ACL reconstruction is likely to result in better functional outcomes, the aim of this study was to compare the short-term functional outcomes of a large consecutive series of patients undergoing ACL reconstruction using the translateral all-inside ACL reconstruction technique (AI) and standard anteromedial portal technique (AM) with a minimum follow-up of one year...

There is emerging evidence in biomechanical studies that suture augmentation of a soft-tissue graft can improve its elongation, stiffness, and load to failure. However, all biomechanical studies have the intrinsic drawback of not considering loosening, accommodation, and mainly, healing. In the past, many very strong and stiff synthetic grafts produced poor results for anterior cruciate ligament reconstruction, and synthetic material inside the joint was abandoned for awhile. Recent studies have shown that it is possible to use synthetic material to augment the graft instead of being the graft itself...
