Summary: This study aimed to explore the associations between different vertical ground reaction forces (vGRF) at each stage of gait post anterior cruciate ligament reconstruction (ACLR) and tibiofemoral articular cartilage magnetic resonance imaging (MRI) T1 rho relaxation times. The results showed that greater vGRF during midstance (46%-56% of stance phase) was associated with lesser proteoglycan density in the medial femoral condyle.

Summary: This study evaluated the effects of whole-body vibration (WBV) and local muscle vibration (LMV) on gait biomechanics in individuals with ACLR. LMV decreased the vGRF loading rate significantly, while WBV increased the peak internal knee extension moment. These findings suggest that vibration has the potential to mitigate aberrant gait biomechanics and reduce the risk of posttraumatic knee osteoarthritis following ACLR.

Summary: The study compared knee-joint reaction forces and impulses during the landing phase of a single-leg forward hop in individuals 12-24 months post-ACLR to uninjured controls. The ACLR group showed lower peak knee flexion angle, knee moments, muscle forces, and joint compressive forces compared to controls, particularly in the patellofemoral-joint. These findings may provide insights into the development of knee osteoarthritis after ACLR surgery.

Summary: The study compared the biomechanics of a standard drop vertical jump (DVJ) with a DVJ while performing a heading motion in soccer. The results showed that the heading DVJ led to decreased knee flexion, increased tibial shear force, and altered trunk and hip angles compared to the standard DVJ. These findings suggest an increased risk of ACL injury in the heading DVJ task.

Summary: Most ACL injuries in professional male rugby players occur through a noncontact or indirect contact mechanism (68%). Three situational patterns were described, including offensive change of direction, being tackled, and pressing/tackling. Biomechanical analysis confirmed a multiplanar mechanism, with a knee-loading pattern in the sagittal plane accompanied by dynamic valgus. As most injuries occurred in the first 40 minutes, accumulated fatigue appears not to be a major risk factor for ACL injury.

Summary: This study proposed a simple method using factor loading to select input variables and applied them to a wavelet neural network model for predicting vertical ground reaction force (vGRF). Kinematic data and vGRF were collected from 9 rearfoot strikers at different speeds, and 9 kinematic variables were selected based on factor loading analysis. The results showed that the predictions of vGRF using this method were effective and accurate, with high correlation coefficients and low errors.

Summary: This study found that preseason field-based tests can predict future noncontact ACL injuries in elite female footballers. Prior ACL injuries, a lower isometric hip adductor to abductor strength ratio, greater CMJ peak take-off force, and greater single-leg triple vertical hop average dynamic knee valgus and ipsilateral trunk flexion were independently associated with an increased risk of subsequent ACL injury.

Summary: This study aimed to investigate the full-body kinematics and vertical ground reaction forces in the lower extremities of ten-pin bowlers. The results showed that there were changes in the joint angles of the dominant wrist and elbow during the later bouts, which were performed to compensate for the change in traction between the ball and the lane. These changes resulted in a decrease in ball release velocity.

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: This study assessed the relationship between walking for exercise and symptomatic and structural disease progression in individuals with knee osteoarthritis (OA). The findings suggest that walking for exercise is associated with a lower frequency of knee pain in individuals with knee OA aged 50 years or older. This supports the recommendation to encourage walking for exercise in people with knee OA and highlights the potential disease-modifying effects of walking, which require further investigation.

Summary: This study found that more healthcare professionals perceive running as beneficial for knee health compared to the general public. Most healthcare professionals feel confident in providing evidence-based recommendations about running and knee health. However, the general public is more likely to believe that frequent running, long-distance running, and running on hard surfaces increase the risk of developing knee osteoarthritis.

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.

Summary: Individuals with anterior cruciate ligament reconstruction and early knee osteoarthritis symptoms often experience psychological impairments, such as pain catastrophizing. This negative response to pain has been linked to more intense pain and reduced functionality in this population. Exploring the neuromatrix theory of pain and the transactional theory of stress and coping can help explain the development and consequences of pain catastrophizing in these individuals. Understanding this relationship can aid clinicians in addressing maladaptive psychological responses and improving outcomes for these patients.

Summary: This study investigates the dance movement kinematics of people with chronic stroke under different types of assistance, including no assistance, safety harness assistance, and contact guard assistance with gait belt. The results show that there is a decrease in joint angle excursions in the no assistance condition compared to the safety harness assistance and contact guard assistance conditions for all song paces. The safety harness and contact guard assistance conditions have similar levels of joint angle excursions, except for higher hip (slow and fast pace) and ankle (medium pace) joint angle excursions in the contact guard assistance condition compared to the safety harness assistance condition.

Summary: Background: Latissimus dorsi transfer is a surgical procedure that can be used for treating posterosuperior rotator cuff tears. However, there is still no consensus on the biomechanical changes resulting from latissimus dorsi transfer.
Methods: We performed a systematic review of the literature on 3D motion analysis studies evaluating the effects of latissimus dorsi transfer on shoulder kinematics.
Findings: Our meta-analysis revealed a significant improvement in forward flexion and abduction following latissimus dorsi transfer. When comparing the latissimus transferred shoulder with an uninjured contralateral side, the meta-analysis found no significant difference in flexion range of motion, while abduction and external rotation were significantly higher in the uninjured shoulders.
