Abstract The invention relates to a hinge joint or swivel coupling in orthopaedic prosthesis and ortheses, with an upper joint component (1), a lower joint component (2) and, if applicable, interposed control arms (9, 10) (hereinafter designated collectively as "hinge joint members") and a control element (4), that effectively engages both sides of a hinge joint member (1; 1, 2) (hereinafter "articulated joint member") each via one hinge point (7, 8) distanced from a pivot (3; 20, 21; 25, 26). To effect an improvement, the invention proposes that at least one of the above-mentioned hinge points (7, 8) is kinematically connected to at least one other hinge joint member (2; 9, 10; 9) via a mechanical geared coupling (11, 12, 13, 14; 15, 16, 17; 18, 24; 30, 31) and is arranged in such a way that it can change position in relation to its articulated joint member (1; 1, 2).
