Abstract: A knee band is composed of a band of an elastic fabric (1), the whole external face (3) of which has a dense population of tiny loops of a suitable non elastic thread, interwoven with other elastic and non elastic threads that constitute the fabric, that extends perpendicularly to the surface such to provide for an anchor surface to the hooks of a Velcro® (i.e., fabric hook-and-loop) fastener portion (2d). The band is tightened essentially around the lower portion of the articulation of the knee, without being wrapped around the whole articulation. A preformed shell (5) shaped for adapting to and shielding the front and side portions of the knee is superimposed externally to the elastic band (1) and is fixed on the outer surface of the latter by means of Velcro® (i.e., fabric hook-and-loop) fasteners.
