Recent research has underscored the importance of teachers' responses to students' peer victimization as well as students' expectations for how their teacher responds to this victimization. However, little research has examined the extent to which teachers and their students have a shared understanding of their teacher's efforts, or lack of efforts, to manage peer victimization. This study addressed this issue using longitudinal data collected on 410 students (47.

- - This study aimed to explore how ankle dorsiflexion (ankle-DF) affects knee and hip movement in females who have undergone ACL reconstruction, assessing 23 participants over 6 months post-surgery.
- - Results showed that lower ankle-DF in the injured leg was linked to increased knee abduction during jumping, while greater ankle-DF in the uninjured leg was associated with more knee and hip flexion.
- - Overall, the findings suggest that reduced ankle motion impacts knee and hip movements differently in the affected and unaffected legs after ACLR.
Background: Aberrant walking-gait and jump-landing biomechanics may influence the development of post-traumatic osteoarthritis and increase the risk of a second anterior cruciate ligament injury, respectively. It remains unknown if individuals who demonstrate altered walking-gait biomechanics demonstrate similar altered biomechanics during jump-landing. Our aim was to determine associations in peak knee biomechanics and limb-symmetry indices between walking-gait and jump-landing tasks in individuals with a unilateral anterior cruciate ligament reconstruction.
View Article and Find Full Text PDFContext: Aberrant biomechanics may affect force attenuation at the knee during dynamic activities, potentially increasing the risk of sustaining a knee injury or hastening the development of osteoarthritis after anterior cruciate ligament reconstruction (ACLR). Impaired quadriceps neuromuscular function has been hypothesized to influence the development of aberrant biomechanics.
Objective: To determine the association between quadriceps neuromuscular function (strength, voluntary activation, and spinal-reflex and corticomotor excitability) and sagittal-plane knee biomechanics during jump landings in individuals with ACLR.
Objective: To determine whether walking speed, collected at 6 and 12 months following anterior cruciate ligament reconstruction (ACLR), is associated with inter-extremity differences in proteoglycan density, measured via T1ρ magnetic resonance imaging, in tibiofemoral articular cartilage 12 months following ACLR.
Methods: Twenty-one individuals with a unilateral patellar-tendon autograft ACLR (10 women and 11 men, mean ± SD age 23.9 ± 2.
Article Synopsis
- The Landing Error Scoring System (LESS) helps identify people at risk of lower extremity injuries, but its current method of manual scoring from video can be slow for clinicians.
- A study at the United States Military Academy tested an automated markerless motion-capture system to see if it could reliably score the LESS quickly and efficiently.
- Results showed that the automated system had a similar reliability to expert raters, with both methods achieving good agreement on most LESS items but struggling with five specific movement errors.
Article Synopsis
- The study aimed to explore the relationship between walking gait biomechanics (like ground reaction forces and knee moments) six months after ACL reconstruction and various biochemical markers related to cartilage health and inflammation.
- Researchers collected data from 18 participants, measuring biochemical markers shortly after ACL injury and again six months post-surgery alongside gait analysis.
- Findings suggested that lower biomechanical performance in the reconstructed limb was linked to negative changes in joint tissue metabolism, which might contribute to future cartilage deterioration.
Article Synopsis
- - A 31-year-old female runner experienced left lateral calf pain for 8 months and went to physical therapy.
- - After a month of treatment, she was referred to an orthopedic doctor, where imaging revealed a 2-cm mass in her calf muscle.
- - The mass was diagnosed as a benign peripheral nerve sheath tumor through ultrasound and biopsy after confirming via MRI.
Article Synopsis
- The study examines how changes in knee movement (kinematics) after ACL reconstruction may affect the forces experienced by the knee (kinetics) during walking.
- Researchers analyzed the walking patterns of 41 individuals who had ACL surgery to see if specific knee angles could predict the peak forces on the ground during their steps.
- Findings indicate that knee flexion excursion in the injured limb can significantly predict peak vertical ground reaction force, suggesting that targeting knee movement could be a potential focus in rehabilitation after ACL surgery.
Background: Previous research has noted sex-based differences in anterior cruciate ligament (ACL) injury rates in young athletes, while little is known about medial collateral ligament (MCL) and meniscal injury rates in this population. The objective of this study was to compare injury rates for traumatic knee injuries (ie, ACL, MCL, and meniscal injuries) in collegiate and high school (HS) varsity student-athletes across multiple sports.
Hypothesis: Knee injury rates vary by sex and across different sports and levels of competition.
