“…Although research into referees and ARs has shown that speed of movement can affect 19 decision accuracy [22,35] the current study did not replicate these findings. In the case of referees, the 20 discrepancy might arise due to the different levels of football considered (youth vs. senior) and the 21 fact that our referees participated in the whole match versus 20 minute segments [35].…”

“…In the anterior cruciate ligament injury literature, greater hip flexion is often associated with greater hip external rotation or a "better" landing motion. 44,45 Because the MAI group demonstrated greater hip flexion, the joint is able to withstand those differences. It is also important for clinicians to evaluate proximal joint strength and range of motion and address those issues at the hip during ankle rehabilitation in case proximal joint kinematic changes occur.…”

Context: Chronic ankle instability (CAI) commonly develops after lateral ankle sprain. Movement pattern differences at proximal joints may play a role in instability.Objective: To determine whether people with mechanical ankle instability (MAI) or functional ankle instability (FAI) exhibited different hip kinematics and kinetics during a stop-jump task compared with "copers."Design: Cross-sectional study. Setting: Sports medicine research laboratory. Patients or Other Participants: Sixty-three recreational athletes, 21 (11 men, 10 women) per group, matched for sex, age, height, mass, and limb dominance. All participants reported a history of a moderate to severe ankle sprain. The participants with MAI and FAI reported 2 or more episodes of giving way at the ankle in the last year and decreased functional ability; copers did not. The MAI group demonstrated clinically positive anterior drawer and talar tilt tests, whereas the FAI group and copers did not.Intervention(s): Participants performed a maximum-speed approach run and a 2-legged stop jump followed by a maximum vertical jump. Main Outcome Measure(s):An electromagnetic tracking device synchronized with a force plate collected data during the stance phase of a 2-legged stop jump. Hip motion was measured from initial contact to takeoff into the vertical jump. Group differences in hip kinematics and kinetics were assessed.Results: The MAI group demonstrated greater hip flexion at initial contact and at maximum (P = .029 and P = .017, respectively) and greater hip external rotation at maximum (P = .035) than the coper group. The MAI group also demonstrated greater hip flexion displacement than both the FAI (P = .050) and coper groups (P = .006). No differences were noted between the FAI and coper groups in hip kinematic variables or among any of the groups in ground reaction force variables.Conclusions: The MAI group demonstrated different hip kinematics than the FAI and coper groups. Proximal joint motion may be affected by ankle joint function and laxity, and clinicians may need to assess proximal joints after repeated ankle sprains.

“…18,19 On the basis of the time-normalized data, the peak external KAM was extracted during the first 50% of the stance phase because this represented a time when the KAM reached its maximal value during walking. Visual 3D software (CMotion Inc, Rockville, MD) was used to define the kinematic model from a static video recording with the participant standing in a neutral position.…”

Context: Lateral subchondral bone bruises (BBs) occur frequently with anterior cruciate ligament (ACL) injuries. These BBs are associated with pain during weight bearing, leading individuals to increase medial tibiofemoral loading to alleviate pain laterally. Increased medial tibiofemoral loading may precipitate the development or progression of posttraumatic osteoarthritis; however, no in vivo biomechanical data exist to confirm that lateral BBs increase medial tibiofemoral loading as measured by the external knee-adduction moment (KAM).Objective: To determine whether lateral BBs after ACL injury increase the external KAM during walking.Design: Descriptive laboratory study. Intervention(s): We recorded peak KAM during 3 walking trials (1.1 6 0.6 m/s) in which participants walked over a force platform located in the field of view of a motion-capture system.Main Outcome Measure(s): Peak KAM was calculated during the first half of stance using standard inverse-dynamics analysis, averaged across trials, and examined via 1-way analysis of variance. Knee pain and function were determined from the International Knee Documentation Committee Subjective Knee Evaluation Form and compared among groups via the Kruskal-Wallis test.Results: Peak KAM did not differ among groups (ACL injury ¼ 0.14 6 0.07 NmÁkg À1 Ám À1 , ACL þ BB ¼ 0.21 6 0.08 NmÁkg À1 Ám À1 , control ¼ 0.20 6 0.08 NmÁkg À1 Ám À1 ; F 2,35 ¼ 3.243, P ¼ .052). Knee-pain frequency and severity were greater in the ACL-injury (frequency ¼ 2.55 6 1.81, severity ¼ 3.36 6 1.75; both P , .001) and ACL þ BB (frequency ¼ 3.58 6 2.81, severity ¼ 4.08 6 3.20; both P , .001) groups than in the control group (frequency ¼ 0.00 6 0.00, severity ¼ 0.00 6 0.00). Knee function was greater in the control group (100.00 6 0.00) than in the ACL-injury (59.35 6 17.31; P , .001) and ACL þ BB (46.46 6 25.85; P , .001) groups.Conclusions: The ACL þ BB groups did not walk with a greater external KAM than the ACL-injury or control groups. Thus, lateral tibiofemoral BB did not influence knee frontal-plane loading after ACL injury.
