The specially shaped insert being covered by an overlay of identical or similar textile material attached to the textile material with the specially shaped insert being associated with a flexible, non-expandable tensioning member. The tensioning member connecting the regions of the kneecap poles on the fibula side in an arc around the kneecap such that, when the distance between the regions increases during bending of the knee joint, the distance of the arc from the connecting line between the kneecap poles is reduced and the tensioning member presses on the adjacent side of the kneecap, medially displacing and centering the latter, wherein the tensioning member is attached to the overlay in such a manner that, during bending of the knee joint and stretching of the overlay, the tensioning member displaces the kneecap.
