ACL Injury

With the start of school upon us many kids will be returning to what they love to do, participating in high school sports. Unfortunately what accompanies that love for sports is an increased risk of injury. Knee injuries have become an epidemic is adolescent athletes with the number of injuries increasing year by year. The anterior cruciate ligament (ACL), which is the primary stabilizer of the knee, is the most commonly injured ligament of the knee. There are approximately 100,000 ACL injuries every year with the majority of these injuries occurring in female athletes. Female athletes are more prone to ACL injuries than male athletes due to many factors including hormonal balances, structural variations, and biomechanic kinematics. Due to the consistent rise in ACL injuries over the last few years, the role of preseason training as a prevention strategy for ACL injury becomes extremely important.

Preseason as well as mid season sport specific training can play a huge role in reducing the occurrence of common knee injuries. Regarding ACL injury prevention, it is important to build up strength of hip, hamstring, and glut muscles. Building up lateral hip strength will prevent the leg from turning in, which puts a high amount of stress on the ACL. At the end of this article are some pictures of common exercises that achieve the goal of building strength and reducing strain on the ACL. If you or someone you know has experienced pain or previous injury with sport activity, the professionals here at Spine & Sport have the expertise required to decrease your chance of re-injury and get you back on the field pain free.
