ACL injury prevention for teen athletes starts before the season, not after an injury.
The two changes that move the needle most are landing mechanics training and a pre-season movement screening that catches risky patterns early.
Programs built around this approach have cut ACL injury rates by 50 to 88 percent in adolescent athletes. For Kitsap County families, that matters right now — fall is when WIAA girls soccer season starts, and most teens haven’t done any of this training since spring.

Why Fall Soccer Season Raises ACL Risk for Washington Teens
Washington is one of the few states where girls’ soccer is a fall sport instead of spring. That scheduling quirk means many athletes spend the summer off the field, then jump into two-a-day practices in August with little sport-specific conditioning behind them.
The first six weeks of the season, when fatigue builds and cutting frequency is highest, is when we see the most ACL injuries walk into our Bremerton clinic.
Why Are Female Athletes More Likely to Tear Their ACL?
Female athletes in soccer and basketball are two to eight times more likely to tear their ACL than male athletes playing the same sport, according to research summarized by UAB Medicine.
The gap comes down to biomechanics, not effort or toughness. A wider hip angle, different landing patterns, and lower hamstring strength relative to quad strength all change how the knee absorbs force when a player cuts hard or lands from a jump.
Age matters too. According to HealthyChildren.org, risk climbs once girls hit puberty, and athletes between 15 and 20 years old account for the largest share of ACL injuries. That’s the exact age range on most Kitsap County high school rosters.
What Actually Prevents ACL Tears — the Numbers
The PEP program (Prevent injury and Enhance Performance), a neuromuscular training routine built specifically for female soccer players, cut ACL injury rates by 88 percent in its first year of use, according to the American Orthopaedic Society for Sports Medicine. FIFA 11+ Kids, a similar program for ages 7 to 14, cut overall injury rates in half.
Both programs take 15 to 20 minutes and replace a normal warm-up. Neither works if a team skips sessions — the research is clear that the benefit disappears in low-compliance groups. Consistency is the whole program.
How Intecore Approaches ACL Prevention Differently
Most ACL prevention advice online stops at a list of exercises.
We start with a movement screen. Before a teen ever steps on the field in pain, we watch how she lands from a jump, cuts off her weaker leg, and decelerates.
A generic exercise handout treats every athlete the same. A screening tells us which specific movement pattern is putting your athlete’s knee at risk, so the training targets that pattern instead of guessing at a general routine.
ACL Prevention Exercises Worth Starting Before the Season
- Single-leg squat to a box — focus on keeping the knee tracking over the toes, not caving inward.
- Nordic hamstring curls, 2 to 3 sets of 6 to 8 reps — builds the hamstring strength that protects the ACL during deceleration.
- Lateral bound and stick — trains the body to absorb force on one leg without the knee collapsing inward.
- Depth jump with a soft landing — teaches the hips and ankles to absorb force instead of the knee taking the load.
These exercises work when they’re done with attention to form, not just reps. A PT watching the first few sessions catches compensations an athlete can’t feel or see in herself.
Frequently Asked Questions
How can I prevent ACL injuries in youth soccer players?
Pair a pre-season movement screening with 2 to 3 sessions a week of landing, cutting, and deceleration training, starting at least six weeks before the first game. Programs built around this cut ACL injury rates by half or more in research on adolescent athletes.
Why are female athletes more likely to tear their ACL than male athletes?
Biomechanics, not effort. Hip angle, landing mechanics, and hamstring-to-quad strength ratios differ between male and female athletes, and those differences change how much force the ACL absorbs during a cut or landing.
What age are ACL injuries most common in young athletes?
Risk rises once athletes hit puberty — around age 12 for girls and 14 for boys — and athletes between 15 and 20 account for the largest share of ACL injuries overall.
How long does it take to recover from an ACL tear?
Most athletes return to sport 9 to 12 months after ACL reconstruction with structured physical therapy. Timelines shift based on graft type, how the surgery went, and how closely the rehab plan is followed.
Can physical therapy really prevent an ACL injury before it happens?
Yes. Prevention programs like PEP and FIFA 11+ are built around exactly this — correcting landing and cutting mechanics before an injury occurs, not after. Consistent participation is what makes the risk reduction real.
