Summary: This study explored the relationship between external knee adduction moment and pain intensity in participants with knee osteoarthritis. The results showed that KAM had a negative effect on VAS pain indirectly through the mediation of KFM, with KAM and KFM being negatively related to each other. The KAM index was found to be negatively related to VAS, suggesting a potential strategy for pain avoidance related to mechanical irritation.

Summary: This study investigated the effects of hindfoot and forefoot eversion on knee displacement, plantar pressure, and foot discomfort in a standing position. The results showed that both hindfoot and entire-foot eversion led to significant medial knee displacement and decrease in EKAM's moment arm, with more pronounced effects observed in entire-foot eversion. Increasing forefoot eversion at each hindfoot eversion angle also resulted in significant medial knee displacement and EKAM's moment arm decrease. Lower leg rotations were not significantly affected in hindfoot-only eversion but displayed significant medial tilting and internal rotation in entire-foot eversion at specific combinations.

Summary: The study proposes a decomposed ground reaction vector (dGRV) model to analyze the components of knee adduction moment (KAM) and their contributions, as well as the effects of medial knee OA, gait speed, and a brace. The dGRV model successfully predicts the KAM profile and identifies the main cause of increased KAM in the OA group. It suggests the need for personalized gait rehabilitation targeting specific components.

Summary: Using insoles to modify walking biomechanics for knee osteoarthritis treatment has been highly researched. However, current insole interventions mainly focus on reducing the peak of the knee adduction moment (pKAM) and have inconsistent clinical outcomes. This study evaluated the effects of different insoles on various gait variables related to knee osteoarthritis and emphasized the importance of considering multiple variables instead of solely focusing on pKAM. The results showed that different insoles had significant effects on gait variables with high variability among patients, and personalized interventions are recommended to address inter-patient variability.

Summary: This systematic review and meta-analysis aimed to determine if exercise interventions are effective in reducing knee adduction moment during gait. The findings suggest that exercise intervention may not be effective in reducing knee adduction moment, and the effect sizes of studies containing only females were significantly greater than studies containing both males and females. Therefore, exercise may not be an effective method for reducing knee adduction moment.

Summary: This study examined the association between sensation-seeking and a student-athlete's concussion-related knowledge, attitudes, perceived social norms, and care-seeking/disclosure behaviors.
Higher sensation-seeking was significantly associated with less favorable concussion attitudes, less favorable perceived social norms surrounding concussion, and continuing to play while experiencing concussion symptoms.
Therefore, athlete with increased sensation-seeking may be at risk for failing to disclose a concussion, decreasing athlete safety and resulting in less optimal care post-injury.

Summary: Adolescents are less physically active than adults after ACL reconstruction, with only 9% of adolescents meeting the aerobic PA guidelines. This is concerning as early PA patterns predict PA patterns in adulthood. Understanding the underlying reasons for reduced PA among adolescents and developing intervention strategies to promote adequate PA after rehabilitation are crucial.

Summary: This study investigated the associations between kinesiophobia, knee abduction angle (KAA), and knee flexion excursion (KFE) in individuals 5-12 months post-ACLR. It was found that higher levels of kinesiophobia were related to greater peak KAA during landing, and modifying kinesiophobia may help reduce the risk of secondary ACL injury.

Summary: The objective of this study was to evaluate the prognostic potential of magnetic resonance-detected meniscal degeneration in predicting destabilizing meniscal tears and accelerated knee osteoarthritis. The study used existing MR data from three groups and found that individuals with medial meniscal degeneration had three times the odds of developing a destabilizing medial meniscal tear within 4 years, while individuals with meniscal degeneration had five times the odds of developing accelerated knee osteoarthritis within 4 years. The presence of meniscal degeneration detected by MR is clinically significant for predicting future poor outcomes.

Summary: Wave elastography typically assumes an isotropic material, but skeletal muscle is usually modeled as a transversely isotropic material with different shear wave speeds along and across the muscle fibers. To address this, a rotational 3-D SWEI system was implemented to measure shear wave speed in both directions in a single acquisition, with automatic detection of fiber orientation. Repeatability testing in healthy volunteers showed a coefficient of variation of 5.3% along the fibers and 8.1% across the fibers. These results suggest that 3-D SWEI has the potential to improve the precision of muscle elastography measurements. No significant difference in shear wave speed was observed between dominant and non-dominant legs along or across the muscle fibers. Rating: 8/10.
