Understanding ACL Injury The anterior cruciate ligament (ACL) is a critical structure that connects the thigh bone (femur) to the shinbone (tibia) and provides stability to the knee joint. When this ligament gets damaged, it can lead to an ACL injury, which often causes pain, swelling, and instability in the knee. Understanding the intricacies of the ACL injury, its impact on the body, and how physical therapy can aid in the recovery process is crucial for effective rehabilitation.
What is Understanding ACL Injury?
An ACL injury occurs when the ligament is stretched or torn, often due to sudden changes in direction, abrupt stops, or direct impact to the knee. Sports that involve pivoting, twisting, and jumping, such as soccer, basketball, and skiing, are common settings for ACL injuries. The injury can range from mild to severe, affecting an individual’s ability to perform daily activities and participate in sports.

Clinically Relevant Anatomy
The ACL is one of the major ligaments within the knee joint, along with the posterior cruciate ligament (PCL), medial collateral ligament (MCL), and lateral collateral ligament (LCL). It plays a vital role in stabilizing the knee during activities that involve twisting or rotational movements. The ligament works in coordination with other structures to ensure smooth and controlled motion of the knee joint.
Functions of ACL
The ACL functions to limit the forward movement of the tibia relative to the femur, preventing the knee from buckling or giving way during physical activities. It also contributes to rotational stability and provides sensory feedback to the brain, aiding in balance and coordination during dynamic movements.
How Does It Feel?
Individuals with an ACL injury often experience a popping sensation in the knee at the time of injury, followed by swelling, pain, and difficulty bearing weight on the affected leg. The knee may feel unstable or give out during movements, impacting the person’s ability to engage in physical activities that require knee stability.
How Is It Diagnosed?
Diagnosing an ACL injury typically involves a comprehensive evaluation by a healthcare professional, which may include a physical examination, imaging tests such as an MRI or X-ray, and a review of the individual’s medical history and symptoms. These assessments help determine the extent of the injury and guide the development of an appropriate treatment plan.
