Summary: This study aimed to identify biomechanical predictors of contralateral knee OA progression after unilateral TKA, but found no significant differences in biomechanical variables between Progressor and NonProgressor groups. Future research should explore alternative measures of OA progression and investigate if joint loading plays a role in worsening OA.

Summary: This study aimed to determine whether specific gait outcomes previously linked to symptomatic medial compartment knee OA are unique to knee OA. The results showed that there were no differences in knee joint kinematics and moments between the knee OA and asymptomatic groups, but the knee adduction moments were greater in the knee OA group compared to the hip OA group. The knee OA group also exhibited a higher activation ratio of the lateral to medial hamstrings compared to the hip OA and asymptomatic groups. This suggests that medial and lateral hamstring muscle activation levels may provide utility as a knee OA gait biomarker.

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: This study assessed the changes in lower limb sagittal plane joint angles during a six-minute walk test for people with mild-moderate knee osteoarthritis. The results showed no significant differences in hip and knee joint angles between the first and last minute of the test, but a reduction in ankle joint plantarflexion was observed in the last minute. There were no significant differences in walking speed or joint range of motion.

Summary: The study compared neuromechanical responses to perturbations during gait among patients with self-reported knee joint instability (KOA-I), patients reporting stable knees (KOA-S), and healthy control subjects. Patients with KOA-I exhibited altered knee joint angles and muscle activation patterns during perturbed gait, which may serve as indicators of knee joint instability and inform treatment options. Longitudinal studies are needed to explore the consequences of altered neuromechanics due to knee joint instability on the development of KOA.

Summary: The mechanical environment of the joint during dynamic activity is crucial in osteoarthritis progression, with a focus on understanding how joint-specific loading features impact disease development and treatment response. Recent evidence highlights significant interest in using biomechanics to understand osteoarthritis structural and clinical progression, joint loading environment, and the role of muscle activation and forces. There is also growing interest in how gait biomechanics variability influences arthroplasty surgery outcomes, with a trend towards tailored treatment approaches and the application of translational biomechanics tools for improved clinical decision-making and outcomes assessment.

Summary: This study aimed to evaluate the underlying domains measured by GaitSmart(TM) parameters in comparison to established OA markers, and found that GaitSmart analysis provides additional information beyond traditional OA outcomes. The study also revealed that GaitSmart parameters are associated with the presence and severity of radiographic knee OA, indicating GaitSmart may be a valuable additional outcome measure for OA evaluation.

Summary: The aim of this study was to evaluate the effects of combined lipid-lowering and antiplatelet strategies on the expression of CCR2, CCR5, and CX3CR1 receptors and the percentage of CCR2, CCR5, and CX3CR1 cells in monocyte subtypes after acute myocardial infarction. The results showed an increase in CCR2 expression and an increase in CCR2+ intermediate monocytes, as well as a reduction in CCR2+ non-classical monocytes after treatment. There was also a decrease in CCR5 expression and an increase in CCR5+ classical and non-classical monocytes. Finally, there were no significant changes in CX3CR1 expression, but a decrease in CX3CR1+ intermediate and non-classical monocytes was observed after treatment.

Summary: This study aimed to evaluate the physical exercise behavior, symptoms of respiratory tract infection, and training practice, as well as aspects of pain and injuries in the lower limbs of adults during periods of lockdown oscillations in Brazil during the COVID-19 pandemic. The results showed that most participants resumed physical exercise after social isolation and reported low rates of injuries and pain symptoms. However, the restrictions negatively affected exercise behavior, leading to an increase in respiratory tract symptoms and a reduction in training intensity without professional supervision.

Summary: This study examined the differences in postural adjustments between erect, hyperlordotic, and swayback postures when facing external perturbations. The findings suggest that adopting hyperlordotic and swayback postures alters the contributions of the active and passive subsystems of the spine in postural control, potentially reducing the spine's ability to withstand loading and shear forces.

Summary: This study investigates the effects of footwear type, navicular drop and ankle pronation on lower limb joint stiffness during running. The results show that navicular drop and dynamic ankle pronation do not affect joint stiffness, but footwear type significantly affects joint stiffness. Conventional footwear increases ankle and hip joint stiffness while reducing knee joint stiffness, which may have implications for injury risk.

Summary: This systematic review is the first to compile evidence on the effect of the menstrual cycle on postural control. The evidence regarding the influence of the menstrual cycle on postural control is unclear. However, a trend of decreased postural control from the early follicular phase to the ovulatory phase was observed in balance tasks that eliminated or altered sensory input.
