The ACL (Anterior Cruciate Ligament) is a ligament that helps to stabilize the knee joint. An ACL tear can be a painful and limiting injury, making it difficult to walk, run, and pivot. An ACL tear can be caused by a sudden twist or pivoting movement of the knee. ACL tears are common in athletes who play sports such as basketball, soccer, and football.
Symptoms of an ACL tear include:
- A popping sound or sensation in the knee at the time of the injury
- Severe pain and swelling in the knee
- Instability in the knee joint, making it feel like the knee is going to give out
