What Is a Meniscus Tear?

To really get a grip on a torn meniscus, it helps to know what the meniscus actually does, right? Well, it's a piece of cartilage, basically, that sits inside your knee joint.

The Importance of a Professional Diagnosis

When your knee hurts, it's natural to wonder, "How do you self check for a torn meniscus?"

Understanding the Torn Meniscus Symptoms Test

When you visit a doctor for knee pain, they'll perform a series of tests to figure out if you have a torn meniscus.

From this position, the doctor will rotate your lower leg while applying pressure to the knee joint. This rotation, combined with bending and straightening, can sometimes cause a click, pop, or pain if there's a meniscus tear.
