Understanding ACL Injury Risk in Female Athletes

Why Female Athletes Face Greater ACL Risk

Female athletes experience ACL injuries at substantially higher rates than male athletes. Depending on the sport and population studied, female athletes have been reported to experience ACL injuries about 2–8 times more often than male athletes. The difference is particularly evident in sports such as soccer, basketball, volleyball, lacrosse, and gymnastics, where athletes frequently jump, land, cut, and rapidly change direction.

A large portion of ACL injuries are non-contact injuries, meaning the athlete does not necessarily collide with another player. Instead, the injury can occur while landing from a jump, suddenly slowing down, planting the foot to change direction, or pivoting. These movements place significant demands on the knee, particularly when an athlete lacks adequate strength, coordination, or control.

There isn't one single reason women experience more ACL injuries. Research points to a combination of anatomical, biomechanical, neuromuscular, and hormonal factors. Female athletes may demonstrate greater knee laxity, differences in knee and hip mechanics, and landing patterns that place greater stress on the ACL. They also tend to demonstrate greater knee valgus and less hip and knee flexion during certain landing and deceleration tasks, which can increase the forces placed on the knee.

The good news is that some of these factors are modifiable through training. Strength training, plyometrics, balance work, and teaching athletes how to properly land, decelerate, and change direction can improve neuromuscular control and movement mechanics.

How Can Athletes Reduce ACL Injury Risk?

An effective ACL injury-prevention program should go beyond simply strengthening the quadriceps. Training should develop the athlete's ability to produce force, absorb force, control the knee, and react quickly.

Exercises and drills can include:

Strength

• Squats

• Split squats and lunges

• Step-ups

• Romanian deadlifts

• Hip thrusts

• Hamstring curls

• Nordic hamstring exercises

• Calf raises

Landing and Plyometric Training

• Snap-downs

• Drop landings

• Jump-and-stick drills

• Single-leg landing drills

• Broad jumps

• Lateral jumps

• Hops and holds

Deceleration and Change of Direction

• Controlled deceleration drills

• 45° and 90° cuts

• Lateral shuffle → plant → accelerate

• Single-leg deceleration

• Sport-specific cutting drills

The emphasis should be on quality of movement, not simply completing more repetitions. Athletes should learn to land under control, maintain appropriate hip and knee alignment, and progressively develop the strength and coordination required to absorb and redirect force.
