Clinical Examination: Often, a torn meniscus can be identified during a physical exam. Your doctor may bend your knee and perform physical exam maneuvers to detect a meniscal tear.
Xrays: Your doctor may also obtain an X-ray of the knee to look for signs of osteoarthritis.
MRI: Magnetic resonance imaging (MRI) is a technique that uses a magnetic field and radio waves to create cross-sectional images of your knee. This is to confirm the diagnosis or study the extent of the tear.
