Patent number: 8579843Abstract: A knee joint bandage made of elastic textile material having a profiled insert encompassing the kneecap in a recess, the insert being covered by an overlay fastened to the textile material. Within the profile insert is a flexible, non-expandable tensioning member for connecting the regions of the kneecap poles on the fibula side in an arc around the kneecap wherein the distance between these regions increases during bending of the knee joint, the distance of the arc from the connecting line of the knee poles is decreased, and the tensioning member presses on the adjacent side of the kneecap, displacing the same medially and centering it. The bandage is provided with a flexible tensioning band, which partially covers the kneecap in its peripheral area relative to the tensioning member, the tensioning band substantially extends in the direction between the kneecap poles such that it counteracts a lifting of the kneecap.Type: GrantFiled: December 19, 2007Date of Patent: November 12, 2013Assignee: Bauerfeind AGInventors: Hans H.
