TL;DR: Altered neuromuscular control of the hip and knee during a dynamic landing task and postural stability deficits after ACLR are predictors of a second anterior cruciate ligament injury after an athlete is released to return to sport.

Abstract: BackgroundAthletes who return to sport participation after anterior cruciate ligament reconstruction (ACLR) have a higher risk of a second anterior cruciate ligament injury (either reinjury or contralateral injury) compared with non—anterior cruciate ligament— injured athletes.HypothesesProspective measures of neuromuscular control and postural stability after ACLR will predict relative increased risk for a second anterior cruciate ligament injury.Study DesignCohort study (prognosis); Level of evidence, 2.MethodsFifty-six athletes underwent a prospective biomechanical screening after ACLR using 3-dimensional motion analysis during a drop vertical jump maneuver and postural stability assessment before return to pivoting and cutting sports. After the initial test session, each subject was followed for 12 months for occurrence of a second anterior cruciate ligament injury. Lower extremity joint kinematics, kinetics, and postural stability were assessed and analyzed. Analysis of variance and logistic regressi...

MRI-based tendon bone healing is related to the clinical functional scores at the first year after anterior cruciate ligament reconstruction with hamstring tendon autograft.
TL;DR: The clinical functional scores and the degree of tendon bone healing were gradually improved over time after ACLR and there were significant positive correlations between the level of tendonBone healing and clinical functional score of knee joint at the first year after the operation.

Are Anterior Cruciate Ligament-reconstructed Athletes More Vulnerable to Fatigue than Uninjured Athletes?
Annemie Smeets,Jos Vanrenterghem,Filip Staes,Hilde Vandenneucker,Steven Claes,Sabine Verschueren +5 more
TL;DR: Overall ACLR athletes and uninjured athletes have similar biomechanical and neuromuscular responses to fatigue, and an interaction effect was found suggesting that landing deficits in ACLR Athletes may become clearer in certain tasks when fatigued.

Motion Task Selection for Kinematic Evaluation After Anterior Cruciate Ligament Reconstruction: A Systematic Review
Eldrich Norwin Chua,Man Yi Yeung,Sai-Chuen Fu,Patrick Shu-Hang Yung,Yu Zhang,Hua Feng,Kai-Ming Chan +6 more
TL;DR: The appropriate selection of motion tasks is an integral factor in dynamic stability testing as it evokes different kinematic outcomes in relation to the different stages of ACLR recovery.

Identification of preferred landing leg in athletes previously injured and uninjured: A brief report.
TL;DR: The leg that first contacts the ground during landing may be a useful strategy to classify preferred landing leg in athletes previously injured and uninjured, as improved limb symmetry was present during hop tests.

Anterior cruciate ligament reconstructed individuals demonstrate slower reactions during a dynamic postural task.
TL;DR: To determine whether individuals with a history of anterior cruciate ligament reconstruction (ACLR) exhibit altered neuromotor function compared to healthy controls, it was hypothesized that the ACLR group would have slower postural responses compared tohealthy individuals of similar age.

Biomechanical Measures of Neuromuscular Control and Valgus Loading of the Knee Predict Anterior Cruciate Ligament Injury Risk in Female Athletes A Prospective Study
Timothy E. Hewett,Timothy E. Hewett,Gregory D. Myer,Kevin R. Ford,Robert S. Heidt,Angelo J. Colosimo,Scott G. McLean,Antonie J. van den Bogert,Mark V. Paterno,Paul Succop +9 more
TL;DR: Knee motion and knee loading during a landing task are predictors of anterior cruciate ligament injury risk in female athletes and may help develop simpler measures of neuromuscular control that can be used to direct female athletes to more effective, targeted interventions.
Mechanisms of anterior cruciate ligament injury.
TL;DR: It is confirmed that most noncontact injuries occur with the knee close to extension during a sharp deceleration or landing maneuver, and passive protection of the ACL by the hamstring muscles may be reduced in patients with above-average flexibility.
