What is ACL Injuries?
The anterior cruciate ligament (ACL) has several functions in the knee. It prevents the lower leg from moving forward on the upper leg, it prevents hyperextension of the knee, it helps stabilize the knee in side-to-side movements, and it helps control the amount of rotation of the lower leg at the knee joint.
More about ACL Injuries
A hard twist, trauma to the knee or excessive pressure on the ACL can tear it, causing the knee to give out so that it can no longer stabilize the joint. Injuries to the ACL occur frequently in sports that involve sudden changes in direction, such as soccer, basketball, and volleyball.
Unless an injured ACL is accurately diagnosed and treated, this injury can lead to other long term issues of the knee as well as problems with the hips and lower back.
