Steinman test can be used to diagnose the meniscal lesions of the knee joint.

Steinman Test is divided into two parts, Steinman Test I and Steinman Test II:
The patient is supine. The examiner immobilizes the patient’s flexed knee with one hand and grasps the lower leg with the other hand. The examiner then forcefully rotates the lower leg in various degrees of knee flexion.
Pain in the medial joint cavity in forced external rotation suggests damage to the medial meniscus; pain in the lateral joint cavity in internal rotation suggests damage to the lateral meniscus. Because the localization of the tear can vary, the test for the Steinman I sign should be performed with the knee in varying degrees of flexion.
The patient is supine. The examiner grasps the knee with one hand and palpates the joint cavity. With the other hand, the examiner grasps the lower leg just proximal to the mortise of the ankle. With the patient’s thigh immobilized, the examiner places the lower leg first in external rotation, then in internal rotation, in each case alternately flexing and extending the lower leg while applying slight axial compression.
Pain in the medial or lateral joint cavity suggests a meniscus injury. The tenderness to palpation in the joint cavity migrates medially and posteriorly during flexion and slight external rotation of the knee; it then migrates proportionally to the pressure and shear forces placed on the meniscus, posteriorly during knee flexion, and back anteriorly as the knee is extended.
Although this test can also be used for an injury to the lateral meniscus, its primary purpose is to help evaluate medial meniscus lesions. A differential diagnosis must consider osteoarthritis and lesions of the medial collateral and capsular ligaments.
A study by Ricardo da Rocha Gobbo to evaluate the accuracy of five special tests for meniscal lesions of the knee joint (McMurray test, Apley test, Childress test and Steinmann test I and Steinmann test II),
The sensitivity and specificity of Steinmann test I for medial and lateral meniscal lesions was:
The sensitivity and specificity of Steinmann test II for medial and lateral meniscal lesions was:
|Test / Meniscus||Medial Meniscus||Lateral Meniscus|
|Steinmann test I||Sensitivity: 69.51%|
|Steinmann test II||Sensitivity: 68.29%|
