The primary outcomes assessed include frequency of ACL-IPP implementation and ACL injury risk.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods<\/jats:title>\n                  <jats:p>This was a prospective cohort study, which followed 671 amateur female soccer players (15.72\u00b11.78 years) whose coaches received either a KTA intervention (n=400) or an educational handout (n=271) regarding implementing an ACL-IPP. Over a single season, we tracked the number of ACL injuries weekly and implementation rates at the end of the season through surveying participating coaches. A \u03c7<jats:sup>2<\/jats:sup> test was used to compare the ACL-IPP implementation rate between the handout and KTA intervention. Cox-hazard proportional regressions were used to examine the effect of implementation rate and educational interventions on ACL injuries.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>The KTA intervention yielded higher ACL-IPP implementation as compared with the educational handout (X<jats:sup>2<\/jats:sup> (1, n=671)=25.87, p&lt;0.001). Implementation of any ACL-IPP at least two times per week was associated with a lower risk of ACL injuries (HR=0.15, 95%\u2009CI=0.03, 0.73; p=0.019) compared with implementing once per week or fewer. The KTA intervention was not associated with a significantly lower risk of ACL injuries (HR=0.39, 95%\u2009CI=0.09, 1.61; p=0.191) compared with the educational handout.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>Stakeholder engagement in the process of planning and execution of IPPs, such as with a KTA intervention, appears beneficial for the purposes of increasing implementation rates. Since implementation was significantly associated with lower rates of ACL injuries, this process may lead to improved results in injury prevention in amateur youth soccer.<\/jats:p>\n
