Kinetics During the Tuck Jump Assessment and Biomechanical Deficits in Female Athletes 12 Months After ACLR Surgery.

Background: Residual interlimb deficits after anterior cruciate ligament reconstruction (ACLR) can lead to functional maladaptation and increase the risk of reinjury. The tuck jump assessment (TJA) may offer a more effective evaluation of ACLR status as compared with traditional tasks owing to increased risk of altered landing mechanics, asymmetrical landing, and increased knee valgus attributed to the cyclical nature of the task. However, it remains unclear whether altered TJA kinetics resolve over time or persist through return-to-play phases of rehabilitation.

Lower ACLR Failure Rates in Bone-Soft Tissue Versus Soft Tissue-Only Allografts in Adults: A Systematic Review and Meta-analysis.

Background: While allografts are commonly used for anterior cruciate ligament reconstruction (ACLR), evidence to guide specific allograft selection is lacking.

Purpose: To compare clinical and graft failure rates after ACLR using soft tissue-only allografts and bone-soft tissue allografts in adults.

Study Design: Systematic review and meta-analysis; Level of evidence, 4.

Evaluation of drop vertical jump kinematics and kinetics using 3D markerless motion capture in a large cohort.

Introduction: 3D Markerless motion capture technologies have advanced significantly over the last few decades to overcome limitations of marker-based systems, which require significant cost, time, and specialization. As markerless motion capture technologies develop and mature, there is increasing demand from the biomechanics community to provide kinematic and kinetic data with similar levels of reliability and accuracy as current reference standard marker-based 3D motion capture methods. The purpose of this study was to evaluate how a novel markerless system trained with both hand-labeled and synthetic data compares to lower extremity kinematic and kinetic measurements from a reference marker-based system during the drop vertical jump (DVJ) task.

Sport-Related Injury and Performance Enhancing Substance Use by Young Athletes.

Background: Legal performance enhancing substance (PES) use is increasing in young athletes and may lead to banned PES use. This study examines legal PES use and consideration of banned PES use in young athletes with a season-ending injury (SEI) compared to young athletes with non-SEI/no previous injury.

Hypothesis: Young athletes sustaining SEI or concussions have increased odds of reporting legal PES use and consideration of banned PES use compared with non-SEI or no injury.

Localized electrocortical activity as a function of single-leg squat phases and its relationship to knee frontal plane stability.

This study investigated differences in electroencephalography (EEG) activity within motor-related brain areas during three phases of a single-leg squat (SLS)-i.e., descending, holding, and ascending phases.

Associations Between Brain Metabolites Measured With MR Spectroscopy and Head Impacts in High School American Football Athletes.

Background: While changes in brain metabolites after injury have been reported, relationships between metabolite changes and head impacts are less characterized.

Purpose: To investigate alterations in neurochemistry in high school athletes as a function of head impacts, concussion, and the use of a jugular vein compression (JVC) collar.

Study Type: Prospective controlled trial.

Youth Sport Specialization: Current Concepts and Clinical Guides.

The concept of youth sport specialization has evolved over the past decade, from a focus on the risk of overuse injury to a broader awareness of its effects on mental health, social well-being, quality of life, growth and maturation, sport performance, and long-term athletic success. This review article considers a recently revised definition of youth sport specialization, as well as guidelines and consensus statements from various sports medicine organizations, with practical applications for young athletes.

Qualitative and quantitative return-to-sport test battery and second anterior cruciate ligament injury risk factors.

Objective: To determine risk factors for second anterior cruciate ligament (ACL) injury following primary ACL reconstruction (ACLR) using return-to-sport (RTS) tests consisting of qualitative and quantitative measures in young athletes.

Methods: A case-control study design was used, and a retrospective review of adolescent athletes after primary ACLR was performed. All athletes completed an RTS test consisting of qualitative and quantitative assessments and psychological assessments with the Tampa Scale of Kinesiophobia.

Effect of Age and Sex on Anterior Cruciate Ligament Functional Tests Approximately 6 Months After Anterior Cruciate Ligament Reconstruction.

Purpose: To examine age- and sex-related differences in postoperative functional outcomes at approximately 6 months after anterior cruciate ligament reconstruction (ACLR).

Methods: In this study, patients who underwent primary ACLR performed a series of return-to-sport functional tests at 5 to 8 months after surgery. Functional tests included strength tests (knee extensors, knee flexors, hip abductors, and hip extensors), a balance test (Y-balance composite score), and hop tests (single, triple, crossover, and 6-m timed hop tests).

Research Letter: Concussion-Related General Startle Suppression in Adolescent Athletes.

Objectives: We investigated the acoustic startle reflex in recently concussed adolescent athletes compared to healthy controls and those with concussion history (>1 year prior) but no current symptoms. We hypothesized that individuals with recent concussion would have a suppressed startle response compared to healthy controls.
