AB  - OBJECTIVE: To determine range of motion (ROM), postural alignment, and dynamic 
      motion differences between those with and without medial knee displacement (MKD) 
      during the overhead squat (OHS). We hypothesized those with MKD would have 
      restricted ROM, differing postural alignment, and poorer quality dynamic motion 
      than those without MKD. DESIGN: Observational. SETTING: University Research 
      Laboratory. PARTICIPANTS: Ninety-seven healthy recreationally active college-aged 
      individuals. INDEPENDENT VARIABLES: Groups were determined by the presence (MKD 
      group) or absence (control group) of MKD during an OHS. MAIN OUTCOME MEASURES: 
      Range of motion measures were active and passive ankle dorsiflexion with the knee 
      straight and bent, hip internal and external rotation, and hip abduction. 
      Postural alignment measures were Q angle, navicular drop, and genu recurvatum. 
      Quality of dynamic motion was measured using total Landing Error Scoring System 
      (LESS) score. RESULTS: The MKD group had significantly less active (P = 0.017) 
      and passive (P = 0.045) ankle dorsiflexion with the knee straight, as well as 
      significantly increased Q angle (P = 0.004) and decreased navicular drop (P = 
      0.009). There were no significant differences in total LESS score or the other 
      outcome measures. CONCLUSIONS: There is select ROM, such as ankle dorsiflexion, 
      and postural measures clinicians can screen for that may be related to increased 
      MKD and theoretically elevated risk of injury.
