What caused my knee to pop loudly when I slipped?

Hello,

Welcome to icliniq.com.

I read your query and can understand your concern.

Based on your story, a loud popping sound in the knee during a fall or sudden twist, especially while catching a ball, raises strong concern for a ligament injury, possibly a tear.

Here are a few likely possibilities that could cause a loud popping sound-

1. ACL tear (anterior cruciate ligament) - This is common in sports-related twisting injuries. Symptoms of an ACL tear are a loud "pop" at the time of injury, immediate or delayed swelling, the knee feeling unstable or giving out when walking, and Pain while twisting or pivoting.

2. Meniscus tear - The cartilage between the thigh and shin bones can tear during a twist, and the tear may cause a popping sensation, locking or catching of the knee, joint line tenderness, and swelling that develops over a few hours

Here is a list of things you must do now:

1. Rest your knee and avoid walking or putting weight on it to prevent the injury from getting worse.

2. Apply ice for about 20 minutes every two to three hours to help reduce swelling.

3. Use a knee brace or wrap to keep the joint stable and supported.

I hope this helps.

Thank you and take care.

Regards.
