(29) Likewise, anterior or posterior root tears of the medial meniscus decrease translational and rotational stability of the knee in both ACL intact and deficient states.
analyzed loading and kinematics in intact knees, knees with a posterior root tear of the medial meniscus, knees with a repaired posterior root, and knees with a total meniscectomy.
Hence, even spontaneous healing without surgical refixation of the posterior root tear might occur as the vascular blood supply of the anterior and posterior horn has been reported to be adequate [34, 35].

In ropivacaine treated groups, there were TUNEL-positive cells in both the grey and white matter, but staining was more intense within the posterior root and the posterior white matter (Figure 4).
We also observed that rats receiving 0.75% and 1% ropivacaine showed no significant alterations in sensory and motor functions after recovery from block, despite the existence of morphologic changes and neuronal apoptosis in the posterior root and posterior spinal cord.
Histopathological studies on light microscopy reveal localized toxic effects of ketamine, vacuoles were seen in posterior root
Meanwhile, the posterior root
of the arterial network is reduced to the proximal part of the internal carotid artery.
It displays anterior and posterior roots
or bars that terminate laterally as anterior and posterior tubercles.
(3) During the 3-5 weeks of gestational age neurulation occurs during which formation of the neural groove, closure of the anterior (25 days) and posterior (27 to 28 days) neuropores, appearance of the ventral horn cells, formation of anterior and posterior roots
and disjunction of the neuroectoderm from the surface ectoderm takes place.
