Can You Really Prevent an ACL Injury?

Posted on June 24, 2014

The answer to this question is not just a simple yes or no. We must first understand some of the factors that need to be considered when talking about the causes of ACL injuries.

Factors Influencing ACL Injury Incidence

ACL InjuryCurrent studies are showing that the highest incidence of ACL injuries is in the ages between 15 to 19 years of age, with significantly more females than males.1 The suggestion is that females have a different shaped pelvis than males, as well as hormonal factors that contribute to ACL injuries

So the answer is no?

Not exactly. It has been reported that only approximately 30% of ACL injuries are from direct contact.2 The majority of non-contact injuries are from slowing down to change direction, and landing from a jump. So the classic example of this is soccer. Due of the aggressive change of direction that occurs throughout the match, there are high numbers of ACL injuries. It is not limited to soccer, however, as many sports, and activities require these movements.

It doesn’t seem like many of these factors are changeable. It’s true. You can’t fight father time, and even though doctors can perform gender re-assignment surgeries, they can’t change your genes. You may have to play on a beat up field, in the rain, but there are critical factors that are completely changeable, and they are your conditioning and neuromuscular coordination.

In a two-year study conducted by the Santa Monica Orthopaedic and Sports Medicine Research Foundation, it was shown that there was an 88% decrease in ACL injuries in the first year, and a 74% decrease in these injuries in year two. Their primary focus was only in the training of neuromuscular coordination. So while you may not be able to prevent every ACL injury, with the proper training in neuromuscular coordination, you can significantly lower your risk.
