Thessaly’s Test
Thessaly’s test assesses for meniscal pathology. To perform this test, ask the patient to stand flatfooted on the floor. You can support the patient by holding their outstretched hands if required. Ask the patient to rotate her knee and body, internally and externally, three times, keeping the knee in 5 degrees of flexion and then again in 20 degrees of flexion. The test is positive if this maneuver produces pain at the medial or lateral joint-line or locking or catching.
