“…The side-to-side differences for the rotational kinematics were similar to previously reported values, 11 but translational differences found in this study were smaller than previously reported. That previous study found average translational differences ranged from 5.3 to 12.8 mm, whereas this study found translational differences ranged from 0.5 mm to 2.2 mm.…”

“…These previous studies of knee kinematic symmetry utilized skin surface markers, 10,11 which lead to inaccuracies associated with soft tissue artifact (STA) of up to 29 mm in translation and 24˚in rotation, depending on the marker location and activity. [14][15][16][17][18] In contrast, biplane radiography can track bone motion during dynamic activities with an accuracy on the order of 1 mm and 1˚.…”

One commonly used criterion in evaluating a patients’ response to knee surgery or rehabilitation is bilateral symmetry. However, the natural symmetry in uninjured healthy adult knee kinematics remains relatively unknown, making it challenging to determine if clinical treatment has adequately restored bilateral symmetry. The primary purpose of this study was to determine the typical side‐to‐side differences in 6 degree of freedom (DOF) knee kinematics over the entire gait cycle in healthy adults using biplane radiography. Six DOF tibiofemoral kinematics were measured during treadmill walking in 19 participants using a validated volumetric model‐based tracking process that matched subject‐specific bone models to biplane radiographs collected at 100 images/s. Average absolute side‐to‐side differences in knee kinematics at foot strike were 1.3 mm or less in translation and 3.8° or less in rotation. Peak side‐to‐side differences in knee kinematics occurred during the swing phase and were up to 2.2 mm in translation and 7.1° in rotation. Dominant versus non‐dominant leg differences were 0.8 mm and 2.8° or less at foot strike and reached maximum values of 0.8 mm and 7.2° over the full gait cycle. Statement of Clinical Significance: This study quantifies the inherent asymmetry of knee kinematics in healthy individuals over the entire gait cycle. The values of asymmetry presented here may serve as a guide for evaluating functional outcomes and restoration of so‐called “normal” kinematics after injury and clinical intervention. © 2019 Orthopaedic Research Society.

Background Biomechanical measurement tools have been developed and widely used to precisely quantify knee anterior-posterior laxity after anterior cruciate ligament (ACL) injury. However, validated objective device to document knee rotational laxity, though being developed by different researchers, are not yet widely used in the daily clinical practice. A new biomechanical device was developed to quantify knee internal and external rotations. Methods The reliability of the new biomechanical device which measures knee rotations were tested. Different torques (1-10Nm) were applied by the device to internally and externally rotate human cadaveric knees, which were held in a flexion angle of 30°. The rotations were measured by the device in degrees. There were two independent testers, and each tester carried out three trials. Intra-rater and inter-rater reliability were quantified in terms of intraclass correlation (ICC) coefficient among trials and between testers. The device was verified by the comparison with a computer assisted navigation system. ICC was measured. Mean, standard deviation and 95% confident interval of the difference as well as the root mean square difference were calculated. The correlations were deemed to be reliable if the ICC was above 0.75. Results The intra-rater and inter-rater reliability achieved high correlation for both internal and external rotation, ranged from 0.959 to 0.992. ICC between the proposed meter and the navigation system for both internal and external rotation was 0.78. The mean differences were 2.3° and 2.5° for internal and external rotation respectively. Conclusions A new knee rotational laxity meter was proposed in this study. Its reliability was verified by showing high correlation among trials. It also showed good correlation to a gold standard of measurement. It might be used to document knee rotational laxity for various purposes, especially after ACL injury, after further validation of the device in human subjects.

“…The kinematic findings of the present study are consistent with those reported in similar studies that illustrate joint movement during walking. 26,29,30 However, this study describes joint movement with ranges of normality that are narrower than those reported by said studies, 22,29,31 which implies lower amplitude graphs. For example, Fryzowicz et al 22 show an articular arc in the sagittal plane of the pelvis close to 6 degrees, while Bruening et al 32 report 4.5 degrees of anteversion in men, which is significantly lower than the 9.5 degrees reported in the present study, thus denoting greater pelvic anteversion in our study population.…”

Parámetros de la marcha en una muestra de adultos sanos colombianos entre 18 y 25 años, un estudio transversal ORIGINAL RESEARCH Abstract Introduction: Gait analysis is fundamental for assessing the functional capacity and motor skills of any individual. Therefore, a reliable and specific analysis method is necessary to study gait in different populations. However, the reference values of gait parameters currently used in Colombia come from studies conducted on population groups from other countries or regions. Objective: To identify the reference values of gait kinematic parameters in healthy Colombian young adults. Materials and methods: A quantitative, descriptive, and cross-sectional study was conducted. The sample consisted of 155 Colombian young adults (aged 18 to 25). Temporal-spatial parameters and kinematics data of each participant were measured through 3D motion capture, which was performed using 8 infrared cameras (Bonita 10) and the VICON NEXUS 1.8.5. software. POLYGON 4.1. software was used for data analysis, and statistical analysis was performed using the STATA 12.1. software package. Results: Average age, height and BMI were 20.3 years, 1.66m and 21.91T kg/m 2 , respectively. 41.29% of participants were male. The average values obtained for the cadence, stride time, speed and initial swing temporal-spatial parameters were as follows: 103 steps/min, 1.16 seconds, 1.01 m/s, and 59.62% of the gait cycle (both sides), respectively. Conclusion: Normal gait kinematic and temporal-spatial parameters of a group of healthy Colombian young adults were obtained, which will allow establishing the characteristics of normal gait in this population, improving intervention strategies, and designing and implementing technical aids aimed at improving locomotion in Colombian individuals.Introducción.
