KNEE ORTHOSIS FOR SUPPORT OF A KNEE JOINT

摘要

A knee orthosis (1) for support of a knee joint in the case of instability comprises a thigh portion (4), which is attachable on the thigh, and a lower leg portion (5), which is attachable on the lower leg, which lower leg portion (5) is provided with splint elements (12), which are connected in an articulated way, via articulation means (13), to hinge plates (14) attached on the thigh portion (4). The lower leg portion (5) has a lower half shell (9), which in the region remote from the knee is borne in the splint elements (12) in a way pivotable about a pivot axis (15). Via a longitudinally stable, flexible traction (17) the lower half shell (9) is pushed ventrally against the lower leg, the pressure increasing with bending of the knee. An optimal support of the knee joint is thereby achieved, especially when the cruciate ligaments are injured.

1. Knee orthosis for support of a knee joint in the case of instability, said knee orthosis comprising:
a thigh portion (4), attachable on the thigh via first fixing means (7), with an upper half shell (6) and hinge plates (14) attached to the upper half shell (6), a lower leg portion (5) attachable on the lower leg via second fixing means (10) with a lower half shell (9), and splint elements (12) attached laterally on the lower half shell (9), wherein:
said splint elements (12) are connected via articulation means (13) to the respective hinge plate (14);in said splint elements (12), in the regions remote from the articulation means (13), said lower half shell (9) is pivotably borne about a pivot axis (15) and is pivotable, via adjustment means (16), toward the lower leg;the adjustment means (16) are formed by at least one longitudinally stable, flexible traction element (17);one end region of the element (17) is held on a member (22; 24) of the articulation means (13) and pivotable with respect to the splint elements (12) by means of a first holding device (18);another end region of the element (17) is held on the lower half shell (9) by means of a second holding device (19);said longitudinally stable, flexible traction element (17) is diverted between the first holding device (18) and the second holding device (19) about a diversion element (20) mounted on the splint element (12).
