“…All the data in Fig. 6 fall within the range identified by Meyer et al (2005). The non-Spray data are consistently lower than the Spray data and none of the non-Spray data exceeds that maximum torque identified in the Meyer et al (2005) study.…”

“…This study was designed to model a cutting maneuver on a hardwood court and determine if the use of traction enhancing products on the bottom of sneakers increases the likelihood of ACL injury. Meyer et al (2005) studied cadaveric knees tested in torsion to failure of the ACL. Their published torsional value of 37.4 ±16.8 N-m (331 ±148.7 in-lbs) resulted in failure of 100% of tested ACLs.…”

Abstract:The knee is one of the most frequently injured joints in the body, between 100 000 and 400 000 Anterior Cruciate Ligament (ACL) injuries occur in the United States each year. This investigation explores the impact of wipe-or spray-on sneaker products used to increase traction between shoes and hardwood courts on the loading of the ACL. Specifically, the maximum torque achieved prior to the sneaker slipping on the court surface is measured using a servo-hydraulic bi-axial load frame. A prosthetic foot fitted into a sneaker was fixed to the load cell and a piece of hardwood court was fixed to the actuator of the load frame. Axial loads were applied to simulate an athlete's body weight and torques were applied to simulate an athlete pivoting on a hardwood surface. The maximum torque achieved prior to the sneaker slipping on the hardwood surface was measured. The investigation finds that the application of the wipe-or spray-on sneaker products increases the maximum torque achieved prior to the sneaker slipping by 164%. This increase in torque exceeds prior published levels of torque that resulted in ACL failure in a cadaveric model.

“…They did not find any significant differences of mean, maximum and minimum which is in agreement with this study. The speed of movement towards knee valgus has also been identified as an injury risk for the medial collateral ligament and ACL [28]. The findings in this study suggests that the brace improves the control of the peak valgus and external rotation velocities which may help in the prevention of ACL injury or help people with ACL deficiency [28].…”

(2016) The effect of proprioceptive knee bracing on knee stability during three different sport related movement tasks in healthy subjects and the implications to the management of Anterior Cruciate Ligament (ACL) injuries. Gait and Posture, 48 . pp. 165 170. ISSN 0966 6362 It is advisable to refer to the publisher's version if you intend to cite from the work. Objective: This study aimed to explore if such improvements in stability may be seen during faster sports specific tasks as well as slower tasks. Method: Twelve subjects performed a slow step down, single leg drop jump and pivot turn jump with and without a silicone web brace. 3D kinematics of the knee were collected using a ten camera Qualisys motion analysis system. Reflective markers were placed on the foot, shank, thigh and pelvis using the Calibrated Anatomical Systems Technique. A two way ANOVA with repeated measures was performed with post-hoc pairwise comparison to explore the differences between the two conditions and three tasks. Results: Significant differences were seen in the knee joint angles and angular velocities in the sagittal, coronal and transverse planes between the tasks. The brace showed a reduction in knee valgum and internal rotation across all tasks, with the most notable effect during the single leg drop jump and pivot turn jump. The transverse plane also showed a significant reduction in the external rotation knee angular velocity when wearing the brace. Discussion: The brace influenced the knee joint kinematics in coronal and transverse planes which confirms that such braces can have a significant effect on knee control during dynamic tasks. Further studies are required exploring the efficacy of proprioceptive braces in athletic patient cohort. Acknowledgements This study is partly founded by Erasmus+ program who have sponsored two masters students. The braces were supplied by DJO Global, Inc. The suppliers played no role in the design, execution, analysis and interpretation of the data or writing of this study.2

“…We analyzed the time point at which the tibial axial forces peaked because authors 18,19 of cadaveric studies have demonstrated that tibial axial force is one of the critical forces that cause noncontact ACL injuries. Meyer and Haut 18,19 investigated whether tibial axial force ruptured the ACL in human cadaver knees and found that increasing tibial axial force increased tibial anterior shift and internal tibial rotation relative to the femur. The ACL of each specimen was ruptured at 5.4 6 2 kN of applied tibial axial force.…”

“…This presumption was based on cadaveric studies 18,19 in which investigators demonstrated that proximal tibial axial forces of sufficient magnitude were transformed into tibial anterior shear forces, especially with posterior slope on the tibial plateau, and eventually rupture the ACL even if no muscle forces are present. Given that GRFs are the largest external forces on the body, particularly immediately after foot contact, researchers 18 have implied that incurring a large GRF that is parallel to the longitudinal axis of the tibia increases the risk of ACL injuries.…”

Context: Ground reaction force (GRF) and tibiofemoral force magnitudes and directions have been shown to affect anterior cruciate ligament loading during landing. However, the kinematic and kinetic factors modifying these 2 forces during landing are unknown.Objective: To clarify the intersegmental kinematic and kinetic links underlying the alteration of the GRF and tibiofemoral force vectors secondary to changes in the sagittal-plane body position during single-legged landing.Design: Crossover study. Setting: Laboratory.Patients or Other Participants: Twenty recreationally active participants (age ¼ 23.4 6 3.6 years, height ¼ 171.0 6 9.4 cm, mass ¼ 73.3 6 12.7 kg).Intervention(s): Participants performed single-legged landings using 3 landing styles: self-selected landing (SSL), body leaning forward and landing on the toes (LFL), and body upright with flat-footed landing (URL). Three-dimensional kinetics and kinematics were recorded.Main Outcome Measure(s): Sagittal-plane tibial inclination and knee-flexion angles, GRF magnitude and inclination angles relative to the tibia, and proximal tibial forces at peak tibial axial forces.Results: The URL resulted in less time to peak tibial axial forces, smaller knee-flexion angles, and greater magnitude and a more anteriorly inclined GRF vector relative to the tibia than did the SSL. These changes led to the greatest peak tibial axial and anterior shear forces in the URL among the 3 landing styles. Conversely, the LFL resulted in longer time to peak tibial axial forces, greater knee-flexion angles, and reduced magnitude and a more posteriorly inclined GRF vector relative to the tibia than the SSL. These changes in LFL resulted in the lowest peak tibial axial and largest posterior shear forces among the 3 landing styles.Conclusions: Sagittal-plane intersegmental kinematic and kinetic links strongly affected the magnitude and direction of GRF and tibiofemoral forces during the impact phase of singlelegged landing. Therefore, improving sagittal-plane landing mechanics is important in reducing harmful magnitudes and directions of impact forces on the anterior cruciate ligament.Key Words: anterior cruciate ligament, tibial posterior slope, lower extremity biomechanics, injury prevention, landing strategy Key PointsAt the impact phase of single-legged landing, sagittal-plane kinetics and kinematics of body segments were strongly related, affecting both the magnitude and direction of the ground reaction force (GRF) and tibiofemoral forces relative to the tibia and anterior cruciate ligament injury risk. A longer time to peak GRF in single-legged landing on the toes with the body leaning forward allowed greater knee flexion, anterior tibial inclination, and shock attenuation, leading to a reduced magnitude of GRF that was more posteriorly inclined relative to the tibia and smaller tibial axial forces and posteriorly directed tibial shear forces. A shorter time to peak GRF during flat-footed landing with the body upright led to less knee flexion, anterior tibial inclination, and s...
