Timing of Anterior Cruciate Ligament (ACL) reconstruction
Background: Anterior Cruciate Ligament (ACL) ruptures are common but the ideal timing for ACL reconstruction following injury is unclear. Objectives: To determine if there is a relationship between timing from ACL rupture to surgery and clinical, functional and patient-reported outcomes. To explore …

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 …

Evaluating Stretch-Shortening Cycle Function in Athletes After ACL Reconstruction Using a Repeat Hop Test
… in athletes following anterior cruciate ligament reconstruction (ACLR). The first study compared three methods for estimating landing velocity during RHT kinetic analysis against traditional temporal methods such as flight time. The results demonstrated that kinetic outcomes were highly sensitive …

Differences in Short-Term Sport-Specific Functional Recovery After Primary ACL Reconstruction in the Adolescent Athlete
The general metadata -- e.g., title, author, abstract, subject headings, etc. -- is publicly available, but access to the submitted files is restricted to UT Southwestern campus access and/or authorized UT Southwestern users.

Strength and power assessment in rehabilitation: profiling the athlete’s return to sport journey following ACL reconstruction
… guidelines following anterior cruciate ligament (ACL) reconstruction including criterion-based progressions to protect healing structures, ensure safe restoration of fundamental physical capacities, and guide appropriate return to sports (RTS) activities. The aim of the proposed research was to …

Understanding the Impact of ACL Reconstruction on Normalization Methods and Identifying Predictive Factors of Landing Symmetry
ACL injuries are one of the most common knee injuries1–4, occurring in 1 out of every 3500 individuals in the Unites States5. Over 200,000 ACL reconstruction surgeries occur each year2,6–9. Following a primary ACL tear, the likelihood of experiencing a second tear increases to 10-25%3,10–15. This …

Evaluation of movement variability and knee biomechanics during functional sporting tasks in healthy individuals and individuals following Anterior Cruciate Ligament Injury (ACL) and ACL reconstruction
… Injury to the anterior cruciate ligament (ACL) is a serious problem which can occur during some sporting activities. Knee biomechanics and movement variability (MV) comprise two very important aspects relating to injury risk, where it has been suggested that the latter may play a role in …

Development and Validation of Clinically Feasible Methods to Assess Landing Mechanics in Patients Following Anterior Cruciate Ligament Reconstruction
… to sport after anterior cruciate ligament (ACL) reconstruction surgery currently have a high risk for sustaining a second ACL injury and having early signs of knee osteoarthritis. Assessing lower extremity kinetics and kinematics during landing can provide information about a patient's risk …

Estudio de la plastia de ligamento cruzado anterior, autóloga vs heteróloga
… Objective To evaluate the percentage of patients ACL reconstruction that return to the sports previous activity. Methodology Retrospective study of 512 patients ACL autólogus reconstruction under the same conditions. Results Only 70 % patients with ACL reconstruction return to the sports previous …

Quadriceps Avoidance Characteristics of Persons with a Reconstructed Anterior Cruciate Ligament during a Forward Lunge
Anterior cruciate ligament (ACL) tears are injuries that often require surgery and physical therapy. Previous research have shown that patients after ACL reconstruction develop a compensatory mechanism called quadriceps avoidance where the use of the quadriceps is avoided and greater knee flexion …

Qualitative and quantitative assessment of functional performance before and after reconstruction of anterior cruciate ligament in people from non-elite/professional sporting background
Reconstruction surgery is a very common management option following rupture of an anterior cruciate ligament (ACL). There is currently no study assessing ACL patients following surgery in Egypt (or other Arabic countries) or in people who are not from competitive sports background. The aims of this …

Design and Analysis of a Collagenous Anterior Cruciate Ligament Replacement
The anterior cruciate ligament (ACL) contributes to normal knee function, but it is commonly injured and has poor healing capabilities. Of the current treatments available for ACL reconstruction, none replicate the long-term mechanical properties of the ACL. It was hypothesized that …

The Effects of Oral Contraceptive Use on Ligamentous Injury Incidence in Females: A Potential for Prevention
… 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 specific mechanisms …
-
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 …

The development and evaluation of virtual reality-based training on performance and rehabilitation outcomes
… (Loes et al., 2000; Sancheti et al., 2010). The ACL is the most common knee ligament injury in rugby, soccer, ski, volleyball, gymnastics, and basketball players due to quick deceleration movements such as landing, pivoting, cutting, and changing direction in these sports. Despite increased …

Inverse Dynamic Analysis of ACL Reconstructed Knee Joint Biomechanics During Gait and Cycling Using OpenSim
<p>ACL (anterior cruciate ligament) injuries of the knee joint alter biomechanics and may cause abnormal loading conditions that place patients at a higher risk of developing osteoarthritis (OA). There are multiple types of ACL reconstruction (ACLR), but all types aim to restore anterior tibial …

Osteogenic Scaffolds for Enhanced Graft-Bone Integration in Ligament Tissue Engineering
… are those to the anterior cruciate ligament (ACL). Annually, approximately 350,000 people require surgical ACL reconstruction, accounting for more than $6 billion of health-care costs in the United States alone. An injured ACL loses its functions as it cannot heal with larger injuries and …

Human studies evaluating dGEMRIC as a prognostic tool for knee osteoarthritis
… 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. Notably, these patients showed …

Estimation of in-vivo forces within Anterior Cruciate Ligament in response to increased weightbearing
The knowledge of Anterior Cruciate Ligament (ACL) forces in-vivo is instrumental for understanding ACL injury mechanisms and for improvement of surgical ACL reconstruction. The goal of this thesis was to develop and implement a non-invasive method to determine the ACL forces under physiological …
