The present invention further relates to a knee joint stabilization system, comprising a first knee joint device and a second knee joint device.
    From the prior art it is known to stabilize knee joints of patients with this purpose specifically designed knee joint stabilization systems for therapeutic purposes. This is necessary, for example, when a knee joint is unstable due to injury or needs to be stabilized after surgery. As is known, the anatomical conditions in different patients have to be taken into account and consequently the knee-joint stabilization system used must be adjusted individually to the respective patient and his anatomy. For this purpose, there are complex solutions, which for example consist in providing a variety of differently constructed knee joint stabilization systems, from which then the most suitable for each patient knee joint stabilization system is selected.
    Alternatively, it is possible to provide a knee joint stabilization system that can be adjusted individually. Such a solution is described for example in document EP 2 329 800 A1. The adjustment is made in particular with regard to the attachment of the knee joint stabilization system on the thigh and lower leg of the respective patient.
    Furthermore, provisions have been made in the prior art to be able to adjust the pivoting between two joint bodies themselves about a pivot axis. In this connection, reference is made to the document DE 10 2010 045 469 A1 and to the further prior art according to WO 2005/032 409 A1.
    It should also be noted that an adaptation to the anatomy of the respective patient must also be made with regard to the positioning of the hinge axis relative to the knee to be supported. A solution for this is described in the document DE 20 005 366 U1.
    The above-mentioned adaptations to the anatomy of each patient lead to relatively complex technical solutions and usually complex steps during the adjustment.
    The present invention has for its object to provide a knee joint device and a herewith equipped knee joint stabilization system, which provide a relatively simple, inexpensive and yet stable structure a good support function for the knee to be supported / offers and relatively easy to the anatomy the patient is customizable.
    The object underlying the invention for the knee joint device is achieved by the features of claim 1, wherein it is provided that the first and the second elongated strut are each made of a metallic material and are plastically deformable to adapt to the anatomy of the patient ,

Furthermore, the inventive knee joint device can thereby also be adapted to the circumference of the thigh, lower leg and the relative position of the knee to be supported for this purpose.
    A preferred embodiment of the invention provides that the first and second elongate struts are made of aluminum. The choice of aluminum has the advantage that this material is available on the one hand cost-effective, on the other hand relatively easily deformable and moreover is relatively dimensionally stable after deformation. It can be provided that during the deformation to facilitate the same, the elongated strut is heated as a whole or locally.
    With regard to the dimensioning can be inventively provided that the first and the second elongate strut have a material thickness between 1.5 and 5 millimeters. Furthermore, it may be provided in this context that the first and the second elongate strut have a width between 15 and 35 millimeters.
    A further development of the invention provides that the two joint bodies are pivotally connected to each other via a hinge pin, wherein the hinge pin is made of plastic or metal. It is possible that at least one of the two joint body is made of plastic.
    In order to keep the production costs and thus the costs for the knee joint device according to the invention and a knee joint stabilization system designed so small, a further development of the invention provides that the knee joint device is made plane symmetrical with respect to a plane perpendicular to the joint axis symmetry plane, so that they are equally on the interior as can be used on the outside of a knee as well as on the left as well as on the right knee. This results in the advantage that in itself only a single type of knee joint devices must be provided, wherein for adaptation to the anatomy of the patient, an individual adaptation of the respective knee joint devices can be made such that these both the left knee and the right knee of the patient on the inside or on the outside can be positioned. Alternatively, it is also possible to provide two different knee joint devices which are specially designed for the inside of the knee and the outside of the knee.
    A development of the knee joint device according to the invention provides that in a state in which the two elongated struts are aligned with each other, the hinge axis is arranged at a predetermined distance to a parallel to the hinge axis center plane of the first and second elongate strut.
    Further, according to the invention can be provided that the two hinge body are formed with means for limiting a pivot angle between the first and the second elongate strut. Thus, it is possible to lock the knee joint device in a certain angular position, for example, to immobilize a knee to be supported. Likewise, it is possible according to the invention to provide a specific swivel angle range or a maximum swivel angle. In this connection, a development of the invention provides that the means for limiting the pivoting angle between the first and the second strut limit the pivot angle to at most 45 °, 90 °, 135 ° or 160 °.
    As indicated several times above, the inventive knee joint device is attached to the thigh and on the lower leg of a patient. For this purpose, it can be provided according to the invention that at least one holding device for attaching fixing means is provided on at least one of the elongated struts at their side remote from the associated joint body. Thus, it is possible according to the invention that the holding device is formed integrally with the respective elongate strut. In particular, it may be provided in this context that the holding device is provided with at least one recess, wherein preferably all the recesses of the holding devices are formed identically. The recesses serve to receive the fixing means such as elastic or inelastic bands with Velcro fasteners.
    In a further development of the invention, the first joint body are further coupled with a third elongate strut and the second joint body further with a fourth elongate strut. The third elongate strut is parallel to the first elongate strut and the fourth elongate strut is parallel to the second elongate strut. Preferably, all elongate struts are arranged along the same plane perpendicular to the hinge axis. However, the elongate struts may also be arranged along different planes perpendicular to the hinge axis. According to the invention, the third and fourth elongate struts may comprise each individual feature or any combination of the features of the first and second elongated struts. In particular, the third and fourth elongate struts may be shaped like the first and second elongate struts. The third and fourth elongate struts may also be made of a metallic material for attachment to a thigh or lower leg of a patient and plastically deformable to conform to the anatomy of the patient.
    The above object is further achieved according to the invention by a knee joint stabilization system, comprising a first knee joint device and a second knee joint device respectively in the manner described above, wherein it is provided that the first knee joint device on the outside of the knee and the second knee joint device on the inside of the knee of the patient are positionable.
    It is possible that in the knee joint stabilization system, the first knee joint device and the second knee joint device can be integrated in a knee bandage. The knee bandage can be made, for example, in the form of a stocking or tubular fashion from an elastic material, which can be stretched across a leg of the patient, as it were, or attached to the patient's leg in the region of the knee via another fixation possibility. The invention will be described below by way of example with reference to the accompanying drawings. It shows:
