“…Mizuno et al [17], Horton and Hall [18] and Koga et al, [19] documented that increases in non-sagittal rotations at the hip and knee, which were shown to be significantly greater in the functional and projected techniques, are associated with the a etiology of injury to the lower extremities. Therefore it appears that researchers should carefully consider their choice of hip joint centre location technique when quantifying non-sagittal rotations and selecting clinical normative data, as it may affect the interpretation of their data.…”

Purpose. The lunge is a fundamental offensive fencing technique, common to all contemporary fencing styles. Therefore, when using 3-D kinematic analysis to quantify lower extremity rotations during the fencing lunge, it is important for researchers to correctly interpret this movement. Locating the centre of the hip is required to accurately quantify hip and knee joint rotations, with three non-invasive techniques using anatomical, functional and projection methods currently available for the estimation of hip joint centre. This study investigated the influence of these three techniques on hip and knee joint kinematics during the fencing lunge. Methods. Three-dimensional kinematics of the lunge were collected from 13 experienced epee fencers using an eight-camera motion capture system. The 3-D kinematics of the lunge were quantified using the three hip joint centre estimation techniques. repeated measures ANOVAs were used to compare the discrete 3-D kinematic parameters, and intra-class correlations were employed to identify similarity across the 3-D kinematic waveforms from the three techniques. Results. The results indicate that whilst the kinematic waveforms were similar (R 2 0.96); significant differences in discrete parameters were also evident at both the hip and knee joint in the coronal and transverse planes. Conclusions. It appears based on these observations that different hip joint centre locations can significantly influence the resultant kinematic parameters and cannot be used interchangeably.

“…The rationale for investigating frontal plane knee kinematics and kinetics is that these variables have previously been shown to predict ACL injuries in female athletes 14 and that a valgus collapse has been identified as a part of the ACL injury mechanism. 5,15,18,28 In addition, existing screening tools developed to identify knee injury risk have focused on frontal plane knee kinematics and kinetics. 10,27,29 Although the real-time assessment of knee control appears to be promising for large-scale screening of athletes, there is a need to investigate the predictive value of such screening for knee injuries.…”

“…[ research report ] E xcessive knee valgus motion has been identified as contributing to noncontact anterior cruciate ligament (ACL) injuries 15,18,28 and is visually associated with a medial collapse of the knee during dynamic tasks. Greater knee valgus angles, side-to-side differences in knee valgus, 12 and lower hip and knee flexion angles 21 have been reported to be more common in females compared to males.…”

Study Design Clinical measurement, controlled laboratory study. Objectives To assess the relationships among real-time observational screening of frontal plane knee control and knee valgus angles and abduction moments calculated from 3-D motion analysis during a vertical drop jump. A secondary purpose was to investigate interrater agreement for 3 independent physiotherapists. Background Current approaches to screen for anterior cruciate ligament injury risk are based on complex biomechanical analyses or 2-dimensional video reviews. There is a need for simple and efficient, low-cost screening methods. Methods Sixty Norwegian elite female football (soccer) players performed a vertical drop-jump task. Using real-time observational screening, 3 physiotherapists independently scored each participant's frontal plane knee control as good, reduced, or poor, based on specific criteria. Screening test scores were correlated to frontal plane knee kinematics and kinetics using 3-D motion analysis. Interrater agreement was determined using kappa correlation coefficients. Results Knee valgus angles differed significantly among players rated as having poor, reduced, or good knee control (10.3° ± 3.4°, 5.4° ± 4.1°, and 1.9° ± 4.3°, respectively). The correlation between the observation test scores and valgus angles was moderate for all raters (0.54–0.60, P≤.001), but the observation scores correlated poorly with abduction moments (0.09–0.11, P>.05). The highest discriminative accuracy was found for knee valgus angles across all raters (area under the receiver-operating-characteristic curve, 0.85–0.89). The interrater agreement between the physiotherapists was substantial to almost perfect, with percentage agreement and kappa coefficients ranging from 70% to 95% and 0.52 to 0.92, respectively. Conclusion Physiotherapists can reliably identify female athletes with high knee valgus angles in a vertical drop-jump landing using real-time observational screening.

“…It is under these dynamic conditions, and in particular within the first 30 to 50 ms after initial ground contact (Koga et al, 2010), that the ACL appears to be most vulnerable to injury from a biomechanical perspective. Females are believed mitigate ground reaction force at the knees in a different manner than their male counterparts, particularly in the frontal and sagittal planes (Hewett et al, 2004Ford et al, 2005b;Hewett, 2008).…”
