- Patient supine with hip flexed 90° and knee flexed 90°
- Examiner palpates the medial joint line anterior to the medial collateral ligament and with the opposite hand, rotates the leg internally and externally by twisting the ankle
- Examiner observes for the presence or disappearance of the meniscus.
Positive Retreating Meniscus Test
Meniscus does not disappear while rotating the leg: Meniscal lesion, tear
This test works on the premise that with the knee flexed 90° to motion of the meniscus should follow the tibia and the meniscus should become more or less prominent with internal or external rotation.
