ACL: The Anterior Cruciate Ligament
The Anterior Cruciate Ligament (ACL) is a ligament that connects the tibia to the femur. It serves to prevent the tibia (leg) from moving forward relative to the femur (thigh). The ACL is in the center of the knee - it crosses the PCL - hence the name - "cruciate".
How does someone injure the ACL?
It is frequently injured in contact sports (such as football) and pivoting sports (such as soccer and skiing) - although there are many scenarios for injury to this ligament. Usually the patient complains of a sudden injury to the knee and the inability to walk right after the accident. Often, there is a significant amount of swelling.
What are the symptoms of an ACL injury?
Initially, the symptoms are pain, and fairly immediate swelling. Often patients will complain of hearing a loud "pop", which is the actual ligament tearing.
After the pain and swelling resolve, patients complain of episodes of instability, or giving-way. The knee feels loose.
