Summary: This study aimed to develop and validate a new concept of flexion axis by calculating points on femoral condyles that maintain constant heights during knee flexion. The results showed that these points form a medial-lateral flexion axis called the iso-height axis (IHA). The IHA exhibited minimal changes in proximal-distal translations and varus-valgus rotations along the flexion path, suggesting interesting clinical implications for knee surgeries.

Summary: This study found that women had greater knee abduction angle and ACL relative elongation than men during various activities, making them more susceptible to ACL injury. The differences in kinematics were minimal, while the differences in ACL relative elongation were relatively stable. These results provide valuable information for identifying abnormal knee kinematics and ACL elongation in athletes after ACL injury.

Summary: The study found that different landing actions have impact on muscle forces and knee joint angles, but not significantly on ACL forces. Factors like knee flexion angle and quadriceps and gastrocnemius forces are critical for ACL injury.

Summary: After ACL reconstruction, there is a lower patellofemoral joint contact force and deficits in quadriceps force and knee flexion angle during side-step cutting tasks. This indicates an increased risk of developing patellofemoral osteoarthritis even after ACL reconstruction.

Summary: Patients with ACLR continue to offload their surgical limb during squatting and landing, with reduced peak vertical ground reaction force, vertical ground reaction force impulse, and peak knee extension moment in the surgical limb. There is a strong relationship between peak knee abduction angle during squatting and landing tasks, whereas the relationships for vertical ground reaction force, knee extension moment, and impulse are moderate to weak.

Summary: The study aimed to describe knee kinetics in baseball hitting, develop a tool to predict knee kinetics, and compare knee kinetics to rehabilitation exercises to determine when hitting can resume after ACL reconstruction. Based on the findings, hitting may be initiated at different time points post-reconstruction depending on whether the involved knee is the front or back one.

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 purpose of this study was to evaluate the midterm functional outcome of traumatic knee joint dislocation and determine the influence of surgical management, patient habitus, and concomitant injuries. The results showed that knee dislocation results in prolonged loss of function and increased knee pain, and concomitant injuries significantly affect clinical outcome.

Summary: This study investigated the effect of whole body parameters on ACL strain and articular cartilage biomechanics during single-leg cross drop and single-leg drop tasks. The results showed that greater knee abduction angle, higher knee anterior shear force, and lower muscle forces were associated with high ACL strain and poor articular cartilage biomechanics.

Summary: Our current understanding of knee mechanics and ACL function is limited to data recorded during simulations or nonphysiologic loads. This study quantified the effects of activity level on knee mechanics and ACL forces during in vivo motions, providing valuable information for ACL reconstruction techniques.

Summary: The study evaluated the influence of time from injury and meniscus tears on the side-to-side difference in anterior tibial translation (SSD-ATT) in ACL deficient patients. Results showed that SSD-ATT was significantly greater in secondary ACL deficiencies, patients with a time from injury greater than 4 years, and with at least one meniscal tear.

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 biomechanical cadaver study evaluated the effects of high-grade posterolateral tibia plateau fractures on the kinematics of ACL-deficient joints, showing that these fractures increase translational and anterolateral rotational instability.

Summary: This study compared in-shoe heel lifts with calf muscle eccentric exercise in reducing pain and improving function in mid-portion Achilles tendinopathy, finding that heel lifts were more effective at 12 weeks. However, the difference in efficacy did not meet the predetermined minimum important difference.

Summary: This study demonstrates that relying solely on accuracy and consistency measures for weapon system acquisition decisions could result in purchasing equipment that is not suitable for the user. Further research is needed to investigate upstream issues such as muscle fatigue and aim point stability for a better understanding of human-weapon-system interactions.

Summary: This study compared gait mechanics between men and women during overground load carriage and found minimal differences between sexes, except for ankle plantarflexion moments. Increasing loads resulted in lower self-selected walking speed, longer stance time, and changes in joint kinematics and kinetics across the gait cycle. The findings may have implications for training programs to improve load carriage performance.
