The anterior cruciate ligament (ACL) is a ligament in the knee that helps to stabilize the joint. ACL injuries are common in sports that involve pivoting or sudden changes in direction, such as football, soccer, and basketball.
Symptoms of an ACL injury
The symptoms of an ACL injury can vary depending on the severity of the injury. Some of the most common symptoms include:
- Sudden pain in the knee
- Swelling
- Inability to bear weight on the leg
- Instability in the knee
- Crepitus (a popping or clicking sound when the knee moves)
Diagnosing an ACL injury
Your doctor will diagnose an ACL injury based on your medical history, your symptoms, and a physical examination. Your doctor may also order imaging tests, such as X-rays or an MRI, to confirm the diagnosis.
Treatment for an ACL injury
The treatment for an ACL injury depends on the severity of the injury. In some cases, the injury may heal on its own with rest, ice, compression, and elevation (RICE). However, in more severe cases, surgery may be necessary to repair the ligament.
Recovery from an ACL injury
The recovery time from an ACL injury varies depending on the severity of the injury and the type of treatment. If the injury heals on its own, the recovery time may be 3 to 6 months. However, if surgery is necessary, the recovery time may be 6 to 12 months.
Preventing ACL injuries
There are a few things you can do to help prevent ACL injuries, including:
- Strengthening the muscles around the knee
- Warming up before exercise
- Wear proper footwear
- Avoid pivoting or sudden changes in direction
