MUSCULUS SARTORIUS BICAUDATUS

While dissecting 88 lower limbs, a distal division of the sartorius mu scle was detected in one of the specimens, The larger posteromedial po rtion was found to take a normal course to the so-called superficial p es anserinus. The thinner anterolateral portion attached to the medial meniscus anteromedially, The smaller anterolateral part approached th e medial meniscus anteromedially, pushing the synovial membrane into t he joint, Its meniscal attachment ensures that the medial meniscus is stabilized in its primary position during bending and external rotatio n in the knee joint, thus preventing its herniation or injury during s udden extension. The accessory part of the sartorius muscle thus acts as a protector of the medial meniscus.
