ACL Prevention: Programs & Results Mike Flynn, MS ATC LAT
Purpose To provide a simple, common sense approach to preventing ACL and lower extremity injuries.
Intended Result To identify the key elements to consider when developing a program. To understand the components of a prevention program. To demonstrate how to effectively implement these components into a program.
Injury Stats 100,000 to 462,000 ACL injuries in the US every year! 85 percent of ACL injuries, regardless of gender, are non-contact! Higher occurrence in females! ( up to 9 times more likely than males)
Prevention Stats Bert Mandelbaum, MD, Santa Monica Orthopedic and Sports Medicine Research Foundation - PEP –Female high school soccer players 2000 season –1,041 in training group, 2 ACL injuries –1,902 in control group, 32 ACL injuries 2001 season –844 in training group, 4 ACL injuries –1,092 in control group, 35 ACL injuries
Prevention Stats Giuliano Cerulli, MD, Santa Maria Hospital associated with the University of Perugia in Italy –900 high-level male soccer players over three seasons 600 in training group, 10 ACL injuries 300 in control group, 70 ACL injuries
Prevention Stats Tim Hewett, PhD, Director of the Sports Medicine Research Institute and Human Performance Laboratory, Children’s Hospital Research Foundation in Cincinnati – Sportsmetrics, WIPP –Female athletes 366 in training group, 2 ACL injuries 463 in control group, 10 ACL injuries
Prevention Stats Oslo Sports Trauma Research Centre, Santa Monica Orthopedic and Sports Medicine Research Foundation, and FIFA – 11+ (2008) –1055 in the training group, 121 lower ext. injuries –837 in the control group, 143 lower ext. injuries
Prevention Stats Swedish Football Association – female soccer players from age 12-17 (2009) –2085 athletes in the control group –2479 athletes in the intervention group 64% reduction of ACL injury rate
Prevention Stats Uppsala Primary Care, Uppsala County Council – HarmoKnee (2010) –777 in training group –729 in control group 77% lower incidence of any knee injury 90% lower incidence of non-contact injury
Prevention Stats Chicago Public Schools – 90 Coaches (2011) –755 athletes in control group –737 athletes in intervention group 35% reduction in overuse lower extremity injuries 44% reduction in acute non-contact lower extremity injuries 34% reduction in non-contact ankle sprains All the athletes with non-contact lower extremity injuries resulting in surgery were in the control, all ACL injuries.
Prevention Stats FIFA - 11+ & Male Basketball Players 11-22 yrs (2012) –14 of 80 players in the FIFA 11+ group were injured –17 of 40 players in the other group had injuries
Prevention Stats Meta-analysis 8 Studies Analyzed –At least 10 minutes of neuromuscular training, 3 times/wk –An ACL tear risk reduction of; 52% in female athletes 85% in male athletes

Retention Program Duration Study – UNC (2012) –140 youth soccer athletes (11 to 17) All participated in either a 3 month or a 9 month program 84 (60%) showed improved LESS scores 3 months following the completion of the programs only the extended duration group retained their improvements
