There are several tests commonly used to diagnose ameniscustear.
McMurray Test
The McMurray Test is the classic manipulation test for meniscal tears.
It involves the full flexion (bending) and rotation of the knee.

The movements are similar to those used in daily activities.
Both legs will be tested to see how therange of motionof the injured knee is affected.
The test is less sensitive than the McMurray Test, with a sensitivity of roughly 65%.
Thessaly Test
The Thessaly Test is performed on your feet.
It is more accurate than the others in detecting medial tears (affecting the inner knee).
The test has a sensitivity of roughly 73%.
Magnetic resonance imaging (MRI)is the imaging study of choice for meniscus tears.
On its own, an MRI has a sensitivity of around 88%.
When combined with two other positive in-office test results, the accuracy may increase to well over 90%.
Arthroscopy
Less commonly,arthroscopymay be needed to definitively diagnose a meniscus tear.
This minimally invasive surgery is commonly performed underlocal anesthesiato view inside the knee joint space.
Arthroscopy is generally avoided unless there is a therapeutic purpose for the procedure.
These tests help detect a tear based on manipulation of the knee.
