    \                 <jats:p>Those with ACLR had weaker quadriceps peak torque in
    the involved limb (P = .001) and greater strength asymmetry (P &amp;lt; .001)
    than control individuals. Normalized hop distance was not statistically different
    between limbs or between groups (P &amp;gt; .05), and hop distance symmetry was
    not different between groups (P &amp;gt; .05). During loading, the involved limb
    demonstrated lesser knee flexion angles (P = .030) and knee power (P = .007) than
    the uninvolved limb and lesser knee extension moments than the uninvolved limb
    (P = .001) and controls (P = .005). During propulsion, the involved limb demonstrated
    lesser knee extension moment (P = .027), knee power (P = .010), knee (P = .032)
    and ankle work (P = .032), and anterior-posterior ground reaction forces (P =
    .047) and greater knee (P = .016) abduction excursions than the uninvolved limb.</jats:p>\r\n

    by the opponent, suggesting poor inhibitory control of the defender. Of the remaining
    21 noncontact ACL injuries (45%), 16 (76%) could be attributed to attentional
    errors. Agreement among the 3 raters was very good for all items except poor decision-making,
    which showed fair to good agreement (Fleiss κ = 0.71). Interrater reliability
    was excellent (intraclass correlation coefficient = 0.99–1.00).</jats:p>\r\n               </jats:sec>\r\n
