Proteoglycan genes and anterior cruciate ligament injury susceptibility
… gene, have previously been associated with anterior cruciate ligament (ACL) injury susceptibility, specifically in females. Proteoglycans have also been implicated in having important functions in fibrillogenesis and maintaining the structural integrity of ligaments. Moreover, their content …

The effects of osteoarthritis, acute voluntary inactivity and injury on skeletal muscle function, Na+, K+ -ATPase content and isoform abundance
… in humans. Knee osteoarthritis, aging, and anterior cruciate ligament (ACL) injury adversely affects muscle mass, strength, and can lead to a reduction in physical activity. The detrimental functional effects seen in osteoarthritis and ACL injury may be partially attributable to physical …

Localizing longitudinal changes in volumetric bone mineral density after acute knee injury using voxel-based morphometry
… such as patients who have sustained an anterior cruciate ligament (ACL) injury, provides a unique opportunity to investigate early disease mechanisms. Early joint changes after an ACL injury often manifest in the peri-articular bone, which can be accurately captured using X-ray-based …

Do the gluteal muscles influence dynamic knee valgus when single-leg landing?
… risk factor in the development non-contact anterior cruciate ligament ACL injury. Gluteal muscles especially gluteus maximus and medius are believed to have a role in controlling hip motion that is associated with dynamic knee valgus. Landing onto one leg is a common scenario of ACL injury …

Learned Biomechanics Through Feedback: Investigating the Transferability of a Jump Landing Task to a Cutting
… to decrease the risk of anterior cruciate ligament (ACL) injury. Currently, jumplanding feedback interventions have demonstrated the ability to alter movements that increase the risk of ACL injury during landing. Unfortunately, it remains unknown if jump-landing …

The Effects of Oral Contraceptive Use on Ligamentous Injury Incidence in Females: A Potential for Prevention
Female athletes have higher incidence of anterior cruciate ligament (ACL) injury compared to males among sports requiring lower limb agility such as soccer and basketball. Often blamed on sex differences in biomechanics and neuromuscular control, current literature has failed to demonstrate …

Human studies evaluating dGEMRIC as a prognostic tool for knee osteoarthritis
… of patients involving an unloading regimen. Anterior cruciate ligament (ACL) injury has previously been shown to be an important risk factor for the development of OA. Patients who had sustained an ACL injury 20 years earlier, who had not undergone ACL reconstruction, were investigated. …

A CRITICAL EVALUATION OF BIOMECHANICAL RISK FACTORS FOR ACL INJURIES DURING DYNAMIC ACTIVITIES
For injury screening to effectively identify individuals with at-risk behaviours, risk factors should be identified and validated carefully through appropriate prospective study designs. In the context of injury prevention in sport, the main aim of screening is to draw a line between those who are …

Investigating the Effects of Modeling and Imagery on Psychological Factors in the Context of a Hypothetical Anterior Cruciate Ligament Injury
… age of twelve experienced an activity-limiting injury. Of these injuries 35% occurred from sport or physical activity (Canadian Community Health Survey, 2009). Although injuries occur most commonly in sport and exercise activities, it is difficult to study injured athletes with similar injuries …

The effect of the Apos Therapy system on knee biomechanics in recreational athletes at risk of a non-contact anterior cruciate ligament injury
An anterior cruciate ligament (ACL) injury is a catastrophicincident in sports, resulting in an extended period away from athletic participation and even potentially ending a playing career. The disparity between positive laboratory results of neuromuscular training programs and the actual effects …

Knee function, movement pattern and knee osteoarthritis in males 14-16 years after an anterior cruciate ligament injury
… knee osteoarthritis in males 14-16 years after anterior cruciate ligament (ACL) injury. In the first study, 154 male subjects with a 14-year-old ACL injury were investigated. Self-reported knee function and radiographic signs of osteoarthritis were assessed. Most of the subjects (122/154) …

Differences in transverse knee moment in healthy, ACL-deficient, and ACL-reconstructed patients during standing target matching
Anterior cruciate ligament (ACL) injury is a common injury affecting nearly 250,000 Americans a year (Boden et al. 2000). Reconstructive surgery costs add up to approximately $1.5 billion annually not including initial evaluation or post-operative rehabilitation (Boden et al. 2000). The anterior …

BIOMECHANICAL RISK FACTORS FOR ANTERIOR CRUCIATE LIGAMENT INJURY: WHAT DO LANDING TASKS TELL US?
The anterior cruciate ligament (ACL) injury is the most debilitating among the knee structure injuries, in terms of severity and economic burden. It mostly occurs in non-contact situations, during cutting, landing, and pivoting manoeuvres, when the impact to the ground exacerbates the knee load and …

An investigation of the Landing Error Scoring System and clinically assessable sport-related injury risk factors
… Error Scoring System (LESS) is a clinical injury risk screening tool suitable for large-scale screening without expensive equipment. However, psychometric properties, influencing factors, and differences in methodological procedures reported between studies need further exploration to …

An investigation into the anatomical and proteomic properties of the anterolateral ligament (all)
ENGLISH ABSTRACT: The anterolateral ligament (ALL) of the knee has recently been a focus of attention, following suggestions that it plays an important role in internal tibial rotation and is involved in the development of anterolateral rotational instability, particularly after anterior cruciate …

Biomechanical Study of Jumping & Landing Techniques: Ballet vs Non-ballet Athletes
<p>INTRODUCTION: The prevalence of ACL injuries is increasing in previous years. One of the most common studied kinematic risk factors related to ACL injuries is a resultant weak, leg axis alignment known as the dynamic knee valgus angle presented during a vertical drop jump [8, 14, 15]. Hewett et. …

Functional tasks before and after an anterior cruciate ligament (ACL) reconstruction : are there mechanical differences?
Anterior cruciate ligament (ACL) injury is a major cause of significant time loss to sports participation, as well as reportedly leading to an increased risk of osteoarthritis (OA). Knee instability and functional adaptations are likely to occur following injury to the ACL, despite many …

Using a Single inertial measurement unit to measure the knee flexion angle at touchdown in side cutting movements
Joint angles can be an important measure in investigating sport-related injuries as well as in rehabilitation studies. Even though previous researchers have investigated using inertial measurement units to calculate joint angles, only a few studies can be found that were conducted using a single …
