Abstract:
Abstract The Anterior cruciate ligament (ACL) is a unique structure and one of the most important ligaments for knee stability, serving as primary restriction for the anterior tibial translation on the femur and secondary restriction to the knee external and internal rotation that is not sustaining weight. The objective of this study was to demonstrate the anatomy and biomechanics of anterior cruciate ligament as well as demonstrate the importance of the anterior cruciate ligament in the stability of the tibial-femoral joint. Literature review was performed using the data bases Scielo, Pubmed and Lilacs having as descriptors: "Anterior Cruciate Ligament", "LCA", "Anatomy" and "biomechanics" from the year 2008 to 2018. The LCA stability for the femorotibial joint and realization of the movement amplitude are in the ability of the anteromedial and posterolateral bands of the same in absorbing the entire load and traction of the joint when in antagonistic movements of the knee flexion and extension, favoring the stability of the tibial-femoral joint. Keywords: Anterior Cruciate Ligament. Anatomy. Knee. Resumo O Ligamento Cruzado Anterior (LCA) é uma estrutura única e um dos mais importantes ligamentos para a estabilidade do joelho, servindo como restrição primária para a translação anterior da tíbia relativa ao fêmur e restrição secundária à rotação externa e interna do joelho que não está sustentando peso. Este estudo teve como objetivo demonstrar a anatomia e a biomecânica do ligamento cruzado anterior bem como demonstrar a importância do ligamento cruzado anterior na estabilidade da articulação tíbio-femoral. Foi realizado revisão da literatura usando as bases de dados Scielo, Lilacs e Pubmed tendo como descritores: “Ligamento Cruzado Anterior”, “LCA”, “Anatomia” e “biomecânica” a partir do ano de 2008 a 2018. A estabilidade do LCA para a articulação femorotibial e realização da amplitude de movimento estão na capacidade das bandas ântero-medial e póstero-lateral do mesmo em absorver toda a carga e tração da articulação quando em movimentos antagônicos de extensão e flexão do joelho, favorecendo na estabilidade da articulação tíbio-femoral.

Abstract:
The knee joint is considered a complex structure, which provides stability and mobility, which is composed of bone, muscle and ligament structures. ACL rupture causes knee joint instability with excessive internal rotation and anterior tibial translation, especially when reaching the last degrees of extension, causing limitations in activities of daily living. This work aims to show the effectiveness of physiotherapy in the treatment of ACL injuries. The method started from a bibliographic review, through books, personal files, websites of medicine and physiotherapy available on the internet, magazines and scientific articles in the health area, aiming to illustrate and theoretically base the work. Articles were selected for the present study, in Portuguese and English. The bibliographic survey was carried out with references to publications between the years 2000 to 2017. The present study revealed the importance of Physiotherapy in the process of rehabilitation of ACL injuries. It demonstrated that most patients respond satisfactorily, and resistance levels can be noticed in a few cases.

Abstract:
Gait analysis is useful for revealing pathologic tibial rotation in children with cerebral palsy (CP), thus guiding interventions of de-rotational osteotomy [1]. Surface marker misplacement may cause an inaccurate definition of the knee flexion axis, which generates downstream artifacts such as cross talk between knee rotation angles and internal rotation errors, misleading these patients’ assessments and surgical interventions [2,3]. Therefore, the purpose of this study was to develop and evaluate a novel method for defining the true knee flexion axis from existing marker trajectories during gait. We hypothesized that the devised method would accurately quantify the offset in the flexion axis due to a systematically misplaced marker and correct the downstream crosstalk and rotation errors of the knee joint angles associated with the marker misplacement.

Abstract:
Kinematic modeling of the knee requires an accurate method to identify the rotational axes [1]. The tibio-femoral joint has two fixed rotational axes: the flexion-extension axis in the femur (FE) and the longitudinal rotational axis in the tibia (LR) [2–4]. Because the knee naturally produces coupled rotation about the LR axis during flexion, attempting to identify the axes from natural flexion alone creates an underdetermined system. A previous study using a mechanical axis finder identified the FE and LR axes by initially identifying the LR axis from pure internal-external (I/E) rotations [4]. Because the major source of error in this method was the visually-based alignment of the axis finder, it should become more repeatable and reliable by utilizing a mathematical optimization to situate the axis finder. Therefore, the two objectives were to develop and validate a new axis finding method, which is based on a mathematical optimization, for identifying the two fixed rotational axes of the tibio-femoral joint.

Abstract:
A validated non-linear 3-D finite element model of human tibiofemoral joint was utilized to investigate the effect of constraint on tibial coupled internal-external and varus-valgus rotations on the passive joint response and force in ligaments under 100N drawer loads at different flexion angles. The model consisted of two bony structures and their articular cartilage layers, menisci and four principal ligaments. For the cruciate ligaments, the results showed that, in the fully unconstrained joint, ACL force decreased with flexion but remained as the primary ligament to resist the posterior femoral load throughout the range of flexion considered. A further significant decrease in ACL force with flexion angle was computed as the joint coupled rotations were constrained. As for PCL ligament, a minor contribution was at full extension under 100N anterior femoral load which further decreased as the coupled rotations were constrained. With joint flexion up to 90°, PCL force, however in contrast to ACL force, substantially increased in both constrained and unconstrained joints. Collateral ligaments, in the unconstrained joint at full extension, were the primary structures to resist the anterior femoral load but had negligible role in posterior-directed load. With joint flexion up to 90°, however, forces in collateral ligaments diminished. Similar trends were computed after fixing coupled tibial rotations with the exception of much greater LCL force and smaller MCL force at full extension under femoral anterior load and larger MCL force in flexion.

The purpose of this study was to develop a cadaveric model for evaluating the relative motion across joint segments in the foot under simulated physiologic loading conditions. The specific aims were to 1) Develop a multi-axis testing platform that simulates three-dimensional (3D) loading conditions through the foot and ankle complex (Achilles load, tibial compression, and internal/external rotation) in a sequential or simultaneous manner, and 2) Evaluate and compare the three-dimensional (3D) kinematics between specific bones of interest in the foot for each individual cadaveric specimen.

Abstract:
Anterior Cruciate Ligament (ACL) rupture is one of the most common serious knee injuries in field and court sports, with an estimated 70% of these injuries being non-contact in nature, often from sudden changes in direction or pivoting [3]. ACL injury results in both short- and long-term consequences for the athlete, which may include surgery, decreased activity levels, elevated pain levels during activities and increased risk of osteoarthritis. Previous studies have shown that knee abduction and tibial internal rotation moments independently strain the ACL, and that these moments have an interaction effect at physiologic load levels, creating strains approaching the reported range of ACL rupture [2, 6–8].

Abstract:
The knee is a complex joint comprised of two main bones (femur and tibia) that articulate in a stable manner through the support of surrounding meniscus, musculature, and ligaments. The anterior cruciate ligament (ACL) is one of the main ligaments connecting the femur to the tibia. The ACL restricts anterior translation of the tibia with respect to the femur and aids in preventing internal and external rotation. The ACL is the most commonly injured ligament in the knee [1] and has been shown to increase the risk of cartilage degeneration leading to osteoarthritis (OA) [2]. The mechanics of the joint are altered following an ACL rupture, but the relations between the resulting joint instability and OA are not well understood.

Abstract:
Over 120,000 anterior cruciate ligament (ACL) injuries occur annually in the United States, mainly affecting the young athletic population. Non-contact injuries are reported to be the predominant mechanism of ACL injury (>70% of ACL injuries), which often occur during landing with high ground reaction forces, muscle forces and segmental inertia. An improved understanding of the mechanisms underlying non-contact ACL injury and inciting events can be used to improve current prevention strategies and decrease the risk of early-onset osteoarthritis. Previous biomechanical and video analysis studies have demonstrated that anterior tibial translation (ATT), knee valgus and internal tibial rotation (ITR) are associated with non-contact ACL injuries [1–3]. While the effects of these factors on ACL injury risk have been extensively studied, there is still controversy and debate about the timing in which these motions occur and reach maximum values during a jump landing task. The current study aimed to investigate interactions between tibio-femoral joint kinematics and ACL strain through a detailed cadaveric simulation of the knee biomechanical response during landing from a jump. For this purpose, instrumented cadaveric limbs were used to simulate bi-pedal landing following a jump utilizing a novel testing apparatus.

Abstract:
The anterior cruciate ligament (ACL) is an important intra-articular structure in the knee joint that prevents excessive anterior tibial translation and resists internal rotational loads. Its rupture is one of the most common injuries of the knee and about 100,000 ACL reconstructions are performed each year in the United States. The current techniques for reconstruction involve replacing the ACL with autografts, most commonly from the hamstrings or patellar tendons, though use of these grafts is associated with various drawbacks, the most prominent of which is donor site morbidity. Over the past 30 years, numerous prosthetic devices for ACL replacement have been made with a wide range of materials. However none of them have demonstrated positive long term results in vivo, and no such devices are currently approved by the FDA for clinical use. Failures of previous devices mostly originate from a lack of biocompatibility due to immunogenic particulation or from mechanical failures causing prosthetic laxity and knee instability as the result of creep or rupture by wear and fatigue.

Abstract:
The ankle joint, comprised of the distal ends of the tibia and fibula as well as talus, is key in permitting movement of the foot and restricting excessive motion during weight-bearing activities. Medial ankle injury occurs as a result of pronation-abduction or pronation-external rotation loading scenarios in which avulsion of the medial malleolus or rupture of the deltoid ligament can result if the force is sufficient [1]. If left untreated, the joint may experience more severe conditions like osteoarthritis [2]. To avoid such consequences, medial ankle injuries — specifically bony injuries — are treated with open reduction and internal fixation via the use of plates, screws, wires, or some combination thereof [1, 3–4]. In this investigation, the mechanical performance of two such devices was compared by creating a 3-dimensional model of an earlier cadaveric study [5], validating the model against the cadaveric data via finite element analysis (FEA), and comparing regions of high stress to regions of experimental failure.

Abstract:
This study investigated movement combinations which may cause injury to the anterior cruciate ligament (ACL). A 3-Dimensional finite element knee joint model, including bones and ligament bundles, was developed. Bone was modeled as rigid, and a transversely isotropic material was applied to the ligament structures. This study incorporates a novel approach for developing bundle specific prestrain within the ligament structures. The bundles were stretched from their zero load lengths to their reference lengths, producing a strain field mimicking in vivo conditions at full knee extension. A failure locus was created by performing multiple knee joint motion combination simulations until ligament failure. The locus shows which movement combinations of internal/external femoral rotation and varus/valgus angle cause failure within the ACL bundles at 25° of knee flexion. The 3D model provided improved accuracy for locating bundle ruptures. By monitoring stresses and strains within the ligament bundles during knee joint orientation simulations, ruptures were virtually diagnosed. The relationship between knee joint orientation and ligament rupture provides a spectrum for the propensity of ACL injury. The results highlight femoral external rotation relative to the tibia as an important factor related to ACL injury. The results also show the posterolateral bundle to be more susceptible to rupture than the anteromedial bundle. These results have various clinical applications. In sports where ACL injuries are prevalent, training programs can be adapted to address the avoidance of harmful knee orientations. Monitoring bundle rupture locations also increases insight for practitioners in identifying more precise injury mechanisms.
