ACL Tear

By: Tori Kearney

What is the ACL?

The ACL (Anterior Cruciate Ligament) is a ligament connecting the three main bones in the knee, which are the femur, tibia, and patella. Two bundles of the ACL, the anteromedial and the posterolateral, serve similar functions in the overall job of the ACL and are named based on their location in the tibial plateau.

ACL Injuries

The ACL can be injured through a number of ways. Even young children today are more frequently facing ACL injures, as sports are becoming more strenuous. Kids are doing the same activities repetitively, which really puts a strain on their ACL. This ligament can be torn by:

Stopping suddenly

Slowing down during sudden movement

Rapid changes in direction

Direct contact


Landing not in proper position (I.E from a jump)

An ACL injury can require years of physical therapy, and almost always requires physical therapy. If not treated properly, it can limit ones lifestyle.

How to prevent an ACL injury

Athletes need to be taught proper mechanics. Although they are not expected to always execute perfectly, after doing countless repetitions of the wrong movement, something will go wrong. In addition, coaches need to vary exercises for athletes. The same movements over and over again strain the ACL, which contributes to a higher probability of a tear. Athletes should also pay attention to health outside of the sport and relax from time to time.
