Torn meniscus may or may not cause symptoms. The ones that do not cause symptoms are usually small tears located in the back of the knee.
Symptoms may include:
- "Popping" sound at the time of the injury
- Swelling within the knee, often called "water on the knee"
- Locking up, catching, or giving way of the knee
- Tenderness in the joint
The doctor will ask about your symptoms and how you injured your knee, and perform a physical exam. The doctor will perform physical tests to decide if there is a tear. Tests may include:
—a test that uses radiation to take a picture of structures inside the body. It will not show a meniscus tear, but may show some bone abnormality.
- MRI scan
—a test that uses magnetic radiation waves to make pictures of the inside of the knee. This is effective in diagnosing a meniscal tear.
—a thin, lighted tube inserted through a small incision in the knee to look at the structures inside the knee. With the arthroscope, the tear will be seen and may be removed or repaired as deemed necessary.
