I hope you are enjoying this series on the ACL.  I have been passionate about preventing and rehabbing these injuries since I began working in PT in 1996.  In today’s post, I am going to briefly discuss one of the critical areas of weakness in athletes that substantially raises injury risk for knees.  Simply put, it is hip abduction weakness.

While I see this in nearly all females, males often have gluteus medius weakness as well.  Why is this an issue?  The gluteus medius is not only responsible for pulling the thigh outward, but more importantly it helps reduce and control rotation/deceleration of the femur with cutting maneuvers.  If you have been reading my blogs or articles, you may see a persistent theme emerging – deceleration matters.

To protect the body from injury, we MUST understand how to train deceleration of the body.  This is often where forces are greatest and present the biggest injury risks.  The hip is a major player in knee prevention programming.  There are lots ofdifferent exercises to strengthen the gluteus medius, but today I will share one of my staples I use in all my knee prevention and rehab programs.  It is called the single leg lateral reach.

Master this move and your knee injury risk will be greatly diminished.  It is an effective way to teach athletes to turn on the gluteus medius and learn how to control the valgus and rotational load with all the weight on one leg.  In the upcoming final ACL post, I will reveal yet another way to improve landing mechanics and body control through a simple lateral plyo maneuver.

In my last post, I spoke about the key components of a successful ACL prevention program.  I also demonstrated a simple drill for teaching proper landing mechanics.  This is just a start.  Most athletes exhibit diminished body awareness/control.  On top of that, female athletes may be up to eight times more likely to suffer a knee injury.

Research has pin pointed many reasons for higher ACL injury risk in females such as:

• Wider pelvis
• Higher Q angle
• Increased ligamentous laxity
• Single leg dominance
• Quad dominance (weak hamstring to quad ratio)
• Potential hormonal implications
• Faulty muscle activation patterns

The list could go on further.  However, the take home message is proper training has been noted to reduce in some cases close to 70% of injuries.  Better yet, these programs can even be coach directed.  The key is doing the right stuff.  Spending as little as 20-30 minutes 2 days a week can make a big impact.  I implemented such a program at an area high school in the pre-season for 30 minutes 2x/week and then once per week in-season.

The team responded well, made it to the district final and did not suffer one ACL injury all season.  I say that not to brag, but rather to tell you that out of 50 plus girls (grade 9-12) not one was injured.  Now, I am also not saying there would have been an injury without me.  But statistically speaking, odds are that 1-2 players per year on each school team will suffer such an injury.  My assumption is the training offered an extra layer of protection.

In addition, the training methods are designed (in my mind) to improve athletic performance too.  Improving body awareness inherently increases athletic movement capacity/skill.  I included a sample session for you to check out below:

Sample Program

Please keep in mind this is one day and not intended to serve as the whole of the program.  Each session should be progressive and sequential, building upon the motor learning that takes place as well as what the performance of the team tells you.
