“…Although no studies have examined the relationship between pitch and change in peak KFM or the knee‐GRF lever arm, lowering the pitch of shoes may indeed influence these parameters by reducing ankle dorsiflexion and knee flexion angles towards barefoot levels. Support for this theory is provided by Lindenberg et al (2011) who explored the association between heel height and knee flexion angle during a forward hopping task in collegiate females [22]. They reported that increasing heel raises from 0 mm to 24 mm, significantly increased the peak knee flexion angle.…”

BackgroundHigher peak external knee flexion moments (KFM) during running has been observed in healthy people wearing athletic footwear compared to barefoot, which may increase risk of knee pathologies such as patellofemoral pain. Currently, no studies have examined whether stability and neutral style athletic shoes influence the peak KFM differently, or explored the underlying biomechanical mechanisms by which footwear alters peak KFM in young females.MethodsLower limb biomechanics of sixty girls aged between 10 and 25 years old were collected while running in footwear (both stability and neutral) and barefoot. The external peak KFM, sagittal plane kinematics, sagittal plane knee ground reaction force (GRF) lever arm and sagittal plane resultant GRF magnitude were analysed by repeated measures Analysis of Variance. Linear mixed models were fit to identify predictors of a change in peak KFM, and to determine if the effects of these predictors differed between footwear conditions.ResultsThe peak KFM was higher wearing both shoe styles compared to barefoot (p < 0.001), while no between-shoe differences were found (p > 0.05). Both shoes also increased kinematic variables at the hip, knee, and ankle (p < 0.05). When all these variables were entered into the mixed model, only a change in the knee-GRF lever arm was predictive of a change in peak KFM wearing shoes compared to barefoot (p < 0.001).ConclusionThese findings provide evidence that stability and neutral shoes increase peak KFM compared to barefoot, which is associated with a change in the knee-GRF lever arm rather than a change in lower limb kinematics. Future studies may consider manipulating footwear characteristics to reduce the knee-GRF lever arm in an effort to reduce peak KFM and the potential risk of patellofemoral pain.Electronic supplementary materialThe online version of this article (10.1186/s13047-018-0307-9) contains supplementary material, which is available to authorized users.

“…puberty) studies investigating the effects of footwear on knee biomechanics. However, previous research involving both healthy [11][12][13][14][15] and populations with knee pathology (e.g. older adults with knee osteoarthritis) [16] have demonstrated a knee load-modifying role of footwear.…”

“…older adults with knee osteoarthritis) [16] have demonstrated a knee load-modifying role of footwear. Specifically, modifying medial and lateral support features of a shoe can influence the resultant frontal (i.e., KAbM) and transverse plane (i.e., KIRM) moments [11][12][13][14][15][16] which may be important in the context of ACL injury, given that combined valgus and rotation increases ACL strain [17]. The athletic footwear market contains a wide variety of both "high-supportive" and "low-supportive" footwear options.…”

“…To counteract these loads, high-supportive shoes with appropriate anti-pronation features [18], might potentially reduce KAbM and/or KIRM. In support, footwear studies investigating the effects of wedges/insoles and orthotics on knee biomechanics [13][14][15]20], have demonstrated their influence on knee loads by altering the frontal plane position of the knee relative to the resultant ground reaction force vector [21,22]. Specifically, laterally arched/ wedged insoles provide a laterally-directed (eversion) bias to the foot shifting the centre of pressure laterally and increasing the KAbM [22].…”

BackgroundHigher landing-related external knee joint moments at later stages of female pubertal development likely contribute to a higher incidence of non-contact anterior cruciate ligament (ACL) injury. Athletic footwear may provide a potential strategy to alter higher knee moments.MethodsThirty-one late/post-pubertal girls (Tanner stage IV-V, menarche and growth spurt attained) performed a single limb drop lateral jump in three footwear conditions (barefoot, low support shoes and high support shoes), in which peak knee abduction moment (KAbM), flexion moment (KFM) and internal rotation moments (KIRM) were measured. Repeated measures ANOVA and ANCOVA were used to test for a main effect of footwear with and without foot posture index (FPI) as a covariate (p < 0.05) with post-hoc test carried out via Fisher’s Least Significant Difference (LSD).ResultsA main effect of footwear condition was observed for peak KFM (p < 0.05), but not KAbM or KIRM, in both unadjusted and adjusted models. Post-hoc analysis demonstrated that both high- and low-support shoes increased peak KFM compared with barefoot (p < 0.001).ConclusionOur findings indicate commercially available high- and low-supportive footwear increase peak KFM, but do not effect KAbM or KIRM while landing among late/post-pubertal girls. This suggests that these styles of footwear are inadequate at reducing higher knee moments in an at-risk cohort.

“…Bilateral drop-landings were performed with subjects standing barefoot with their arms folded across their chest on a height-adjustable platform (to the nearest 0.01 m). All landings were performed barefoot so as to prevent any heel elevation associated with footwear from altering landing mechanics and weakening internal validity (20). Subjects were then instructed to step-off the platform, leading with the right leg, before immediately bringing the left leg off and alongside the right leg before impact with the ground.…”

This study examined the effects of a 4-week ankle-mobility intervention on landing mechanics. Twenty participants with restricted ankle dorsiflexion range of motion (DF ROM) were allocated to either a strength training only (n = 9) or a strength training and ankle mobility program (n = 11). Participants performed a weight-bearing lunge test and bilateral drop-landings before and following the intervention. Normalized peak vertical ground reaction force (vGRF), time to peak vGRF and loading rate were calculated, alongside sagittal-plane initial contact angles, peak angles and sagittal-plane joint displacement for the ankle, knee and hip. Frontal-plane projection angles were also calculated. Following the intervention, only the strength and mobility group improved ankle DF ROM (mean difference = 4.1°, effect size (ES) = 1.00, P = 0.002). A one-way analysis of covariance found group effects for ankle joint angle at initial contact (P = 0.045), ankle (P < 0.001) and hip joint angle at peak flexion (P = 0.041), and sagittal-plane ankle (P < 0.001) and hip joint displacement (P = 0.024) during bilateral drop-landings. Post-hoc analysis revealed that the strength and mobility group landed with greater ankle plantar flexion at initial contact (mean difference = 1.4 ± 2.0˚, ES = 0.46) and ankle dorsiflexion at peak flexion (mean difference = 6.3 ± 2.9˚, ES = 0.74) following the intervention, resulting in greater ankle joint displacement (mean difference = 7.7 ± 4.0˚, ES = 1.00). However, the strength training only group landed with increased peak hip flexion (mean difference = 14.4 ± 11.0˚, ES = 0.70) and hip joint displacement (mean difference = 8.0 ± 6.6˚, ES = 0.44) during post-testing. The findings suggest that changes in landing strategies following the performance of a strength training program are specific to whether restrictions in ankle mobility are considered as part of the intervention.
