ACL Injury
An ACL (anterior cruciate ligament) injury is a common knee injury that frequently occurs during sports activities involving sudden stops, changes in direction, or pivoting movements. The ACL is a vital ligament that provides stability to the knee joint, and its injury can significantly impact an individual’s ability to participate in sports and perform daily activities. This article aims to provide an overview of ACL injuries, including their causes, symptoms, and available treatment options.
Causes of ACL Injury
ACL injuries typically occur due to sudden movements or trauma that put stress on the knee joint. Some common causes of ACL injury include:
- Sports Injuries: Activities that involve high-impact movements, such as soccer, basketball, skiing, and football, can lead to ACL injuries. These injuries often occur during abrupt stops, jumps, or changes in direction.
- Non-Contact Injuries: ACL injuries can also occur without direct contact with another person or object. A sudden change in direction or landing awkwardly from a jump can put excessive stress on the ACL, leading to injury.
- Trauma: Car accidents or falls that result in a direct blow to the knee can cause ACL tears.
Symptoms of ACL Injury
When an ACL injury occurs, individuals may experience the following symptoms:
- Audible "pop" or snap at the time of injury.
- Immediate pain and swelling in the knee.
- Inability to bear weight on the affected leg.
- Instability or a feeling of the knee "giving way" during movements.
- Limited range of motion in the knee joint.
