Background: Knee abduction moment during landing has been associated with anterior cruciate ligament (ACL) injury. However, accurately capturing this measurement is expensive and technically rigorous. Less complex variables that lend themselves to easier clinical integration are desirable.

Background: The triple hop for distance test commonly uses a limb symmetry index (LSI) 'pass' threshold of >90% for total hop distance following anterior cruciate ligament reconstruction (ACLR). However, understanding the manner in which athletes generate and dissipate forces during consecutive hops within the test may provide greater insight into residual limb deficits. The aim of the study was to examine reactive strength ratios (RSR) of individual hops during a triple hop test in a cohort of ACLR patients at discharge prior to return-to-sport.

The purpose of this clinical trial was to examine whether internal jugular vein compression (JVC)-using an externally worn neck collar-modulated the relationships between differential head impact exposure levels and pre- to postseason changes in diffusion tensor imaging (DTI)-derived diffusivity and anisotropy metrics of white matter following a season of American tackle football. Male high-school athletes (n = 284) were prospectively assigned to a non-collar group or a collar group. Magnetic resonance imaging data were collected from participants pre- and postseason and head impact exposure was monitored by accelerometers during every practice and game throughout the competitive season.

Femoroacetabular impingement (FAI) is a common anatomical variant in ballet dancers. Cam morphology (a subtype of FAI) and increased alpha angles have been identified as risk factors for hip pain. Ultrasound has recently been used to measure alpha angles in the diagnosis of cam morphology, but its utility remains understudied.

Sports medicine clinicians face conflicts of interest in providing medical care to athletes. Using a survey of college football players, this study evaluates whether athletes are aware of these conflicts of interest, whether these conflicts affect athlete trust in their health care providers, or whether conflicts or athletes' trust in stakeholders are associated with athletes' injury reporting behaviors.

Background/aim: There is a lack of consistency in return to sport (RTS) assessments, in particular hop tests to predict who will sustain a reinjury following anterior cruciate ligament (ACL) reconstruction. Inconsistent test battery content and methodological heterogeneity might contribute to variable associations between hop test performance and subsequent injury. Our aim was to investigate whether commonly used hop tests are administered in a consistent manner and in accordance with reported guidelines.

Background: The physeal-sparing iliotibial band (ITB) anterior cruciate ligament (ACL) reconstruction (ACLR) is a well-established technique for treating skeletally immature patients with ACL rupture. However, the long-term implications of the procedure on the intricacies of kinetic and kinematic function of the knee have not been comprehensively investigated.
Purpose: To assess the short-, mid-, and long-term effects of ITB ACLR on kinetic and kinematic parameters of knee functions.

Background: The functional elbow range of motion in children and adolescents has not been previously reported. In adults, a functional motion arc of 30 to 130 degrees of elbow flexion and 50 degrees of pronation to 50 degrees of supination is well established. Contemporary tasks such as cellular phone use and keyboarding require greater elbow flexion and pronation than the functional motion arc.

We performed a retrospective study of patients seen at a specialty pediatric concussion clinic. Patients were 18 years of age or younger, examined within 10 days of concussion, and received care until full recovery.

Examining association between serial participation in youth organized sports (OS) and concurrent cardiometabolic risk factors, with long-term health status, will aid understanding the role of OS participation. Combining data from a prospective study and a follow-up survey, we aimed to determine association between youth OS participation and cardiometabolic risk factors with health and physical activity (PA) in young adulthood. Cardiometabolic risk factors were monitored yearly, and OS involvement through middle school, high school, and college, together with current status was recorded 12 years after the initial study began; 462 participants completed follow-up.

Background: Concussion prognosis is a challenging clinical task. Identification of measures useful for persistent symptom risk can help optimize treatment pathways and allow clinicians to offer appropriate anticipatory guidance.
Research Question: Can a multifaceted single/dual-task postural control assessment within one week of a diagnosed concussion identify the odds of developing persistent post-concussion symptoms (PPCS; symptoms that persist for more than 28 days post-concussion)?
Methods: We conducted a prospective cohort study of youth and young adult athletes who were evaluated within 7 days of injury, and followed until they no longer reported concussion symptoms.

Public concern is growing about the short- and long-term effects of pediatric mild traumatic brain injury (mTBI). This concern is amplified because pediatric mTBI has the potential to go undiagnosed in acute care settings, placing children at increased risk for reinjury prior to complete recovery. The management of mTBI can be particularly challenging due to the lack of validated biomarkers that clinicians can use to objectively diagnose pediatric mTBI, predict risk for prolonged recovery, or demonstrate mTBI recovery.
