OBJECTIVES: Anterior Cruciate Ligament (ACL) deficiency may result in abnormal lower limb loading with increased foot pronation. This study evaluated spatiotemporal parameters and plantar pressure distribution during walking in participants with and without an ACL rupture. DESIGN: Cross-sectional. METHODS: Plantar pressure was measured in 42 unilateral ACL deficient (ACLD) participants and 32 healthy controls while walking barefoot. Spatiotemporal parameters, pressure distribution and center of pressure (CoP) during foot roll off were determined...

BACKGROUND: Anterior cruciate ligament (ACL) reconstruction with ST autograft is sometimes unsuccessful because of harvested thin graft. Magnetic resonance imaging (MRI) can be a useful tool to evaluate the thickness of the graft. This study is performed to evaluate whether there is any correlation between diameters and cross-sectional area (CSA) of the semitendinosus tendon (ST) on the preoperative magnetic MRI and the diameter of the 4-stranded ST autograft in ACL reconstruction. MATERIALS AND METHODS: Seventy patients who underwent single-bundle ACL reconstruction with 4-stranded ST for full-thickness ACL ruptures were included in this study...

BACKGROUND: Anterior cruciate ligament (ACL) reconstruction using tendon or ligament autograft is the gold standard surgical treatment for acute ruptures; however, this is still associated with subsequent problems and variable outcomes. Renewed interest in healing of injured ACL tissue has led to new surgical repair techniques. CASE DESCRIPTION: We report the case of one of the first patients to undergo this novel procedure of ACL repair with internal bracing. An internal brace is a bridging concept using braided suture tape and knotless bone anchors to reinforce ligament strength...

Reverse Segond fracture is originally described as an indirect radiographic clue for a specific injury complex of the knee joint that includes posterior cruciate ligament (PCL) rupture and medial meniscal tear. Herein, we describe a case with reverse Segond fracture associated with PCL avulsion fracture instead of PCL rupture. According to current literature review, reverse Segond fracture is not only associated with PCL and medial meniscal injuries, but also frequently associated with anterior cruciate ligament (ACL) and medial collateral ligament (MCL) injuries...

OBJECTIVES: The extracellular matrix (ECM) of ligaments continuously undergoes remodelling in order to maintain tissue homeostasis. Several key mediators of ECM remodelling were chosen for investigation in the present study. It is thought that polymorphisms within genes encoding signalling molecules may contribute to inter-individual variation in the responses to mechanical loading, potentially altering risk of injury. DESIGN: A genetic association study was conducted on 232 asymptomatic controls (CON) and 234 participants with surgically diagnosed anterior cruciate ligament (ACL) ruptures; of which 135 participants reported a non-contact mechanism of injury (NON subgroup)...

INTRODUCTION: The use of the semitendinosus tendon alone for anterior cruciate ligament reconstruction keeps the gracilis muscle intact and decreases anterior pain in comparison with the use of the patellar tendon. Recently, Lubowitz described a new all-inside technique with an ST4 tendon fixed with a cortical button in both femoral and tibial sides. We hypothesized that this type of graft with cortical button fixation provides well-controlled residual anterior tibial translation (<3mm)...

Lesions of the anterior cruciate ligament (ACL) are common; the current gold standard of treatment for such lesions is ACL reconstruction. Tibial-sided soft-tissue avulsion is a rare subtype of ACL injuries. Unlike femoral-sided ACL repair, surgery for acute tibial-sided ACL ruptures has been neither reported nor described. This technical note presents a method for primary anatomic ACL reinsertion for an acute distal soft-tissue avulsion-type ACL injury, using a transosseous pull-out repair technique. Our technique, as an alternative to reconstruction, has the potential to enhance healing due to marrow stimulation (tibial tunneling)...

Ramp lesions of the medial meniscus are commonly associated with anterior cruciate ligament ruptures and consist of longitudinal peripheral tears of the posterior horn of the medial meniscus. Given the frequency of partial-thickness tears, they can be difficult to diagnose arthroscopically from the anterior compartment. We describe a classification of the different types of ramp lesions depending on both tear pattern (partial- or full-thickness tear) and associated meniscotibial ligament disruption. An original technique of arthroscopic suture placement through a single posteromedial portal with a 25° curved suture hook device is described...

BACKGROUND: This paper reports the outcomes of patients undergoing ACL reconstruction using a TransLateral single bundle, all-inside hamstring technique at a minimum of two year follow-up. METHODS: The semitendinosus alone is harvested, quadrupled and attached in series to two adjustable suspensory fixation devices. Femoral and tibial sockets are produced using a retrograde drill. The graft is deployed, fixed and tensioned on both tibia and femur. Patients were evaluated preoperatively using the KOOS, Lysholm and Tegner scores and at six, 12 and 24months postoperatively...

Familial predisposition is among the major genetic risk factors for non-contact musculoskeletal tissue injuries. Personal genome sequence shows that different polymorphism profiles may account for the number and the degree of injuries and the recovery time. Genotyping studies allow investigation into genome factors with potential impact on pathogenesis of non-contact ligament injuries. We have studied a family with twin sibling males surgically diagnosed of an anterior cruciate ligament non-contact rupture and non-affected progenitors (father and mother) were subjected to whole exome sequencing (WES) analysis...

Osteoarthritis (OA), the most common musculoskeletal disease in the United States, is characterized by cartilage breakdown, pain, and restricted movement. Post-traumatic OA (PTOA) occurs subsequent to traumatic joint injury, such as anterior cruciate ligament (ACL) rupture, and makes up 12% of the overall disease burden, with healthcare costs of approximately $3 billion/year. The current paradigm for PTOA is based on the observation that joint injury affects multiple tissues, all of which may contribute to subsequent joint failure...

PURPOSE: The purpose of the study was to report the functional outcome following anterior cruciate ligament (ACL) reconstruction in patients who decide when to resume work and normal sporting activity post-operatively. The hypothesis tested was that patient-based decision to return to work and sport was possible without compromising functional outcome and increased the rate of repeat rupture in comparison with the existing literature. METHODS: This was a monocentric, retrospective study...

BACKGROUND: Recommendations for bone tunnel placement during anterior cruciate ligament (ACL) reconstruction have become more precise. However, these recommendations differ neither with the choice of graft nor with the method of fixation used. The influence of the method of femoral fixation used on the biomechanical function of a soft tissue ACL graft remains unknown. HYPOTHESIS: Our null hypothesis was that adding femoral aperture fixation to femoral cortical fixation, using the same bone tunnels, will not alter the control of anterior translation (AT) and internal rotation (IR) during ACL reconstruction using a hamstring graft...

INTRODUCTION: For successful anterior cruciate ligament (ACL) reconstruction, revascularisation and histological maturation are necessary, as their failure can cause graft rupture. PURPOSE: The purpose of this study was to describe differences in the histological maturation of early failed plasty (less than 12 months after surgery) and late failed plasty (more than 12 months after surgery) in patients with re-rupture after ACL reconstruction with hamstring tendons...

CONTEXT: The most commonly injured body part for skiing was found to be the knee. The rupture of the anterior cruciate ligament (ACL) was the most frequent diagnosis. ACL ruptures are determined by several extrinsic and intrinsic risk factors, including those which are hormonal, neuromuscular, anatomical or genetic. OBJECTIVES: To examine the association of both COL1A1 rs1800012 (+1245G/T) and COL1A1 rs1107946 (-1997G/T) polymorphisms, individually and as haplotypes, with anterior cruciate ligament ruptures in recreational Polish skiers...

Anterior cruciate ligament (ACL) tears are a common knee injury with a known but poorly understood association with secondary joint injuries and post-traumatic osteoarthritis (OA). Female sex and age are known risk factors for ACL injury but these variables are rarely explored in mouse models of injury. This study aimed to further characterise a non-surgical ACL injury model to determine its clinical relevance across a wider range of mouse specifications. Cadaveric and anaesthetised C57BL/6 mice (9-52 weeks of age) underwent joint loading to investigate the effects of age, sex and body mass on ACL injury mechanisms...

In this study, we examined early time-dependent changes in articular cartilage and synovium in response to tibial compression and sought the plausible origin of cells that respond to compression in the healer (LGXSM-6) and non-healer (LGXSM-33) recombinant inbred mouse strains. The right knee of 13-week old male mice was subjected to tibial compression using 9N axial loading. The contralateral left knee served as a control. Knees were harvested at 5, 9 and 14 days post-injury. Histological changes in cartilage and synovium, immunofluorescence pattern of CD44, aggrecan, type-II collagen, cartilage oligomeric matrix protein and the aggrecan neo-epitope NITEGE, and cell apoptosis (by TUNEL) were examined...

Mid-substance rupture of the canine cranial cruciate ligament rupture (CR) and associated stifle osteoarthritis (OA) is an important veterinary health problem. CR causes stifle joint instability and contralateral CR often develops. The dog is an important model for human anterior cruciate ligament (ACL) rupture, where rupture of graft repair or the contralateral ACL is also common. This suggests that both genetic and environmental factors may increase ligament rupture risk. We investigated use of bone marrow-derived mesenchymal stem cells (BM-MSCs) to reduce systemic and stifle joint inflammatory responses in dogs with CR...

INTRODUCTION: Medical history and physical examination are expected to provide the basic knowledge allowing diagnosis of a disease and thus enabling to plan the course of treatment. OBJECTIVE: This study aimed to examine this hypothesis by comparing pre-operative diagnosis of meniscal and anterior cruciate ligament (ACL) injuries to final surgical findings. MATERIAL AND METHODS: We prospectively compared the pre-surgical diagnosis to the arthroscopic findings in 753 arthroscopic procedures...
