This electromyographic study shows that the popliteus muscle is a prime medial rotator of the tibia on the femur. Apparently its action during rotation and flexion of the knee also is to withdraw and protect the lateral meniscus. By giving rotatory stability to the knee, it appears to prevent forward dislocation of the femur on the tibia during flexion of the knee.
