Knee’ed to Know
Out of the 40 million children that participate in sports ever year in the United States, Sports Medicine Doctor Mark Purnell states “ACL injuries are estimated to occur 250,000 times per year in the U.S. alone.”(Purnell 10). Lindsay Berra, ESPN columnist, explains what the ACL is, “The anterior cruciate ligament, one of four ligaments that stabilize the knee, is a rubber band-like fiber no bigger than your pinky. It runs through the center of the knee joint, attaching the thigh bone to the shin bone.” (Berra   One of the ACL’s primary purposes is to provide stability to the knee for activities that involves cutting, landing, jumping, twisting, and running. Approximately 30,000 girls who are 19 and younger will choose to have an Anterior Cruciate Ligament reconstruction each year according to the study that Lindsey had conducted. Many studies have been shown by various doctors and medical exterminators that young women are eight times more likely to tear their ACL’s than a young men. Girls tear their ACL’s more frequently than boys due to their anatomy, biomechanics, and finally by not being properly trained and prepared.  
As we all know, men and women have different anatomy. So why does this matter when it comes to tearing of ACL’s? Well that’s because the knee in males is structurally different than the female’s knee. Everyone’s ACL is located in the between the intercondylar notch of the knee. However, males have a larger notch than women do. This being said, the female has a smaller intercondylar notch and thus a smaller ACL. Due to the smaller size, the ACL is weaker and more stress is placed on this ligament. The room for movement for the ACL is just limited. When the female knee moves, especially during any twisting or cutting motion, the ACL is being pinched and then at risk of a rupture or tear.
It is known that the female pelvis is wider than the male...
