Abstract

The knee bandage comprises a sleeve (20) for the thigh and a sleeve (21) for the leg connected by a first diagonal strip (22) crossing a second diagonal strip (23). Between the cross-over point of the diagonal strips (22, 23) and the sleeve (20) for the thigh, a strip-free loacation is provided for the ball-joint. The sleeves (20, 21) may have a closed annular shape or be open, and have fixing means (25) at their ends. A process for determining the position of the intermediate strips of the bandage consists in making a projection of the part to be supported of the anatomical ligament and/or muscular apparatus onto the periphery of the knee joint, and in placing the intermediate strips along the projection. These intermediate strips may also be placed along the geometrical resultant of two or more projections.

Description

KNIEBANDAGE KNEE BANDAGE
Die Erfindung betrifft eine elastische Kniebandage vom Typus zum Hineinschlüp fen oder zum Anlegen, vorzugsweise eine zum Anlegen offene Kniebandage.The invention relates to an elastic knee brace of the type to slip into or put on, preferably an open knee brace for putting on.
Zum prophylaktischen Schutz des Kniegelenks, aber auch zur Unterstützung der Funktion eines leicht oder schwerer geschädigten oder des alternden Knies, dienen aller Art Knie-Bandagen und -Orthesen. Kniebandagen unterstützen durch ihre elastische Uirkung den Band- und Muskelapparat, während die Knieorthesen mit nicht-elastischen, knochenfunk t ionsähnlich starren Elementen Band- und Muskelapparat des Knies noch zusätzlich festigen und unterstützen sollen. Scharnierstellen von Orthesen sind jedoch schwierig zu plazieren und vor allen Dingen in den Bewegungsablauf einzubringen. Ein sich beugendes Knie verhält sich jedoch nicht wie ein einfaches Scharnier mit einem festen Drehpunkt, vielmehr verschiebt sich dieser kontinuierlich beim Abrollen des Condylus, was biomechanisch sehr schwierig nachbildbar ist. So bewähren sich immer noch die elastischen Unterstützungsmechanismen in Form von Bandagen aller Art. Es ist nun das 2iel der Erfindung eine Knie-Bandage zu schaffen, deren elastische Zugwirkungen den Band- und Muskelapparat des Knies gezielter unterstützen, als dies bei einfachen elastischen Kniebandaoen der Fall ist.All types of knee supports and orthoses are used for prophylactic protection of the knee joint, but also to support the function of a slightly or severely damaged or aging knee. The elastic effect of knee supports supports the ligaments and muscles, while the knee orthoses are supposed to additionally strengthen and support the ligaments and muscles of the knee with non-elastic, bone-like rigid elements. However, hinge points of orthoses are difficult to place and, above all, can be incorporated into the movement process. A bending knee, however, does not behave like a simple hinge with a fixed pivot point, rather it moves continuously as the condyle rolls, which is very difficult to reproduce biomechanically. The elastic support mechanisms in the form of bandages of all kinds are still proving their worth. It is now the goal of the invention to create a knee bandage, the elastic pulling effects of which support the ligamentous and muscular apparatus of the knee in a more targeted manner than is the case with simple elastic knee tights.
Dieses Ziel wird erreicht, durch ein Ober- und Unterschenkelband mit einer kreuzfachen Bandanlage dazwischen, die im wesentlichen medial nach lateral und vice versa verläuft.This goal is achieved by a thigh and lower leg ligament with a cross fold ligament between them, which runs essentially medially laterally and vice versa.
Die Erfindung geht von folgender Idee aus. Der Anteil der knöchernen Führung ist beim Kniegelenk trotz markanter Zug-, Druck- und Torsionsbel astungsfähigkeit recht gering, die Hauptbelastung wird vom passiven Band- und vom aktiven Mus- kelapparat getragen, welche das Kniegelenk "zusammenhalten". Dazu haben sich nebst einfachen, direkten Verbindungen wie bspw. das Ligamentum col laterale, auch mehr oder weniger stark gekreuzte Verbindungen wie bspw. das Ligamentum - cruciatum anterius im Zusammenspiel mit dem Ligamentum - cruciatum posterius (Kreuzbänder) als stärker oder wie die menisci.als schwächer gekreuzte Verbindungen. Während die steiler gekreuzten Kreuzbänder im Bereich zwischen den - Kondylen angeordnet sind, umschlingen die schwächer gekreuzten Menisken die Kondylen im Aussenbereich. Die kollateralen Bänder sowie das Ligamentum patallae mit dem Tendo quadricipitis (Kniescheibensehne) verbinden die Femur mit der Tibia und Fibula in direkter Verbindung. Alle diese schräg bis gerade verlaufenden Verbindungen werden in praktisch jedem Belastungsfall, Zug-, Druck-, Rotationsbelastung Lind Mischformen davon, in ihrem Zusammenspiel optimal belastet. Diesen Mechanismus echt nachbildende Kniebandagen kann es aus Anordnungsgründen nicht geben, aber durch Projektionen dieses biologischen Halte-Apparates an die Gelenkperipherie mit dem Verlauf derProjektion folgenden elastischen Bänder, lässt sich eine sehr gute Gelenkhilfe realisieren. Projiziert man bspw. die Lage der Kreuzbänder lateral und/oder medial sowie anterior und/oder posterior, so können elastische Bänder einer Kniebandage diesen Projektionen nachgeführt werden oder in einer Vereinfachung folgt die Bandführungeinzelnen Resultierenden von Projektionen.The invention is based on the following idea. The proportion of bony guidance in the knee joint is quite low despite the striking tensile, compressive and torsional load capacity, the main load is borne by the passive ligament and the active musculoskeletal system, which "hold" the knee joint. In addition to simple, direct connections such as the ligamentum col laterale, there are also more or less crossed connections such as the ligamentum - cruciatum anterius in interaction with the ligamentum - cruciatum posterius (cruciate ligaments) as stronger or like the menisci.als weaker crossed connections. While the steeper crossed cruciate ligaments are arranged in the area between the condyles, the weakly crossed menisci surround the condyles in the outer area. The collateral ligaments and the ligamentum patallae with the tendo quadricipitis (patellar tendon) connect the femur with the tibia and fibula in a direct connection. All these inclined to straight connections are optimally loaded in their interaction in practically every load, tensile, compressive, rotational load and mixed forms thereof. Knee braces that really replicate this mechanism cannot exist for reasons of arrangement, but they can be projected of this biological holding device on the joint periphery with the elastic bands following the course of the projection, a very good joint aid can be realized. If, for example, the position of the cruciate ligaments is projected laterally and / or medially as well as anterior and / or posterior, elastic ligaments of a knee brace can be tracked to these projections or, in a simplification, the ligament guidance follows individual results of projections.
Ein herstellungsmässig besonders einfaches, aber biomechanisch sehr wirksames Ausführungsbeispiel wird nun anhand der nachfolgenden Figuren eingehend diskutiert.An embodiment that is particularly simple in terms of production but is very effective biomechanically will now be discussed in detail with reference to the following figures.
Figur 1 zeigt einen Längsschnitt durch ein Kniegelenk mit den hervorgehoben dargestellten Kreuzbändern.Figure 1 shows a longitudinal section through a knee joint with the cruciate ligaments shown highlighted.
Figur 2 zeigt schematisch ein angewinkeltes Kniegelenk von der Seite undFigure 2 shows schematically an angled knee joint from the side and

Figur 4 zeigt eine danach gearbeitete Kniebandage in räumlicher Anordnung undFigure 4 shows a knee brace worked afterwards in a spatial arrangement and
Figur 5 diesselbe auseinandergelegt.Figure 5 disassembled the same.
Der Längsschnitt gemäss Figur 1 zeigt hervorgehoben einen Teil des anatomischen Bandapparates, nämlich die Kreuzbänder, im Schnitt durch die Fossa, also zwischen den Kondylen der Femur 1 und der Tibia 2. Sichtbar ist das vordere Kreuzband 10 und das hintere Kreuzband 11, die vor dem Condylus medialis 12 liegen. Die Patella (Kniescheibe) 4 ist zwischen Tibia und Femur durch die Kniescheibensehne 13 und die Sehne 14 des Trizeps in ihrer Lage gehalten. Die Fibula 3 ist in Figur 1 nicht eingezeichnetThe longitudinal section according to FIG. 1 shows highlighted part of the anatomical ligament apparatus, namely the cruciate ligaments, in section through the fossa, that is, between the condyles of the femur 1 and the tibia 2. The anterior cruciate ligament 10 and the posterior cruciate ligament 11, which are in front of the Medial condyle 12 lie. The patella (patella) 4 is between the tibia and the femur through the patella tendon 13 and the tendon 14 of the triceps held in place. The fibula 3 is not shown in FIG. 1
Figur 2 zeigt nun die Konturen einer Röntgenaufnahme eines Kniegelenks in leichter Beugestellung bei tibio-fibularem Strahlengang. Darin eingezeichnet sind Projektionen der Kreuzbänder 10,11 und die kollateralen Bänder 15. Mit 10' sind die ungefähren Ansatzstellen des vorderen und mit 11' des hinteren Kreuzbandes bezeichnet. Ferner sind Projektionen der Kniebandage darübergezei chnet, nämlich die Schenkelmanschetten 20,21 und die Di agonalbänder 22,23. Im gezeigten Beispiel greift das Diagonalband 22 an der Stelle M medial (zwischen den Beinen) an und verläuft schräg nach unten unter der Kniescheibe vorbei zur Stelle L, wo das Diagonalband 22 dann lateral (Knieaussenseite) verankert ist. Das andere Diagonalband 23 verläuft von der Knieaussensei te schräg nach unten zur Knieinnenseite. In der abstrakt gezeigten Projektion fallen die Diagonalbänder zusammen.Figure 2 now shows the contours of an x-ray of a knee joint in a slightly bent position with a tibio-fibular beam path. Projections of the cruciate ligaments 10, 11 and the collateral ligaments 15 are shown therein. 10 'denotes the approximate attachment points of the anterior cruciate ligament and 11' of the posterior cruciate ligament. Projections of the knee brace are also shown, namely the thigh cuffs 20, 21 and the diagonal bands 22, 23. In the example shown, the diagonal strap 22 engages medially (between the legs) at the point M and runs obliquely downwards under the kneecap to the point L, where the diagonal strap 22 is then anchored laterally (outside of the knee). The other diagonal band 23 runs from the knee outside diagonally downward to the inside of the knee. In the abstract projection shown, the diagonal bands collapse.
Figur 3 zeigt die Konturen einer Röntgenaufnahme des ungefähr gestreckten Knies bei anterio-posteriorem Strahlengang mit denselben Projektionen des Bandapparates und d&r Kniebandage wie in Figur 2. Gut zu sehen sind nun die Bandage- Diagonalbänder 22 und 23, wie sie sich unter der Kniescheibe kreuzen. Bei beiden Figuren 2 und 3 erkennt man den gleichsinnig ähnlichen Verlauf der Bandage- Diagonalbänder 22,23 mit den Kreuzbändern 10,11 des Kniegelenks, die so durch die Zugwirkung der elastischen Bandage- Bänder im Belastungsfall teilentlastet werden. Dies ist auch beim gebeugten Knie der Fall (Figur 2). Der diagonale Verlauf der Di agonalbänder unterstützt die Haltewirkung des Band- und Muskelapparat des Kniegelenks bei Rotationsbewegungen zwischen Femur und Tibia: bei den Kreuzbändern entlastet das Bandage- Di agonal band 22 bspw. das hintere Kreuzband 11 und das Bandage- Diagonalband 23 das vordere Kreuzband 10. Direkt werden auch die kollateralen Bänder 15 in ihrer torsionshemmenden Wirkung unterstützt. Ferner bewirken die rund um Ober- und Unterschenkel laufenden Schenkelmanschetten, durch Druck auf die Schenkel- Muskeln eine indirekte aktive Unterstützung der muskulären Verbindungsstellen im Kniegelenk. Damit ist eine sozusagen zwiefache, Wirkung erreicht, nämlich die aktive und passive Unterstützung des Muskel- und Bandapparates.FIG. 3 shows the contours of an x-ray of the approximately stretched knee with an anterior-posterior beam path with the same projections of the ligament apparatus and the knee brace as in FIG. 2. The bandage diagonal braces 22 and 23, as they cross under the kneecap, can now be seen clearly. In both Figures 2 and 3 you can see the similarly similar course of the bandage diagonal bands 22,23 with the cruciate ligaments 10,11 of the knee joint, which are thus partially relieved by the tensile action of the elastic bandage bands in the event of a load. This is also the case with the knee bent (Figure 2). The diagonal course of the diagonal ligaments supports the holding effect of the ligament and muscle apparatus of the knee joint during rotational movements between the femur and the tibia: in the cruciate ligaments, the bandage diagonal ligament 22 relieves, for example, the posterior cruciate ligament 11 and the bandage diagonal ligament 23 the anterior cruciate ligament 10. The collateral ligaments 15 are also directly supported in their torsion-inhibiting effect. Furthermore, the thigh cuffs that run around the thighs and lower legs provide indirect active support for the muscular connection points in the knee joint by applying pressure to the thigh muscles. This has a twofold effect, so to speak, namely the active and passive support of the musculoskeletal system.
Im Gegensatz zu den im Handel erhältlichen Kniebandagen, die ihre Stützfunktion nur durch Querdruck ausüben, bewirkt die vorliegende Konstruktion durch den Zug der Diagonalbänder auch eine ausgeprägte Stützwirkung in der Längsrichtung.In contrast to the commercially available knee bandages, which only perform their supporting function by means of transverse pressure, the present construction also provides a pronounced longitudinal support by the pulling of the diagonal bands.
Als Quasi -Resultierende von weiteren Bandapparateteilen des Kniegelenks, bspw. der fast im Bein längsverlaufenden kollateralen Bänder mit den fast zum Bein quer verlauifenden, wenig schräg stehenden Menisken, werden diese durch die Diagonalbänder der Kniebandage ebenfalls unterstützt. Die gezeigte Ausführungsform hat, wie gezeigt eine bemerkenswerte biomechanische Wirkung auf das Kniegelenk.As a quasi-resultant of other parts of the ligamentous apparatus of the knee joint, e.g. the collateral ligaments that run almost longitudinally in the leg with the menisci that are almost oblique to the leg, these are also supported by the diagonal ligaments of the knee support. As shown, the embodiment shown has a remarkable biomechanical effect on the knee joint.
Ferner besticht die gezeigte Ausführungsform durch einen relativ einfachen Aufbau, der keine herstellungstechnischen Probleme mit sich bringt. Wie Figur 4 zeigt, besteht diese Kniebandage aus zwei Schenkelmanschetten 20,21, die hier in einer offenen Version mit Verschlussbändern 25 dargestellt sind, und aus zwei an den Schenkelmanschetten befestigten gekreuzten Diagonalbändern 22 und 23. Die Schenkelmanschetten sind in der Regel für Ober- und Unterschenkel verschieden gross, entweder einstellbar, bspw. mittels dem praktischen Klettenverschluss, oder fest, durch ungeteilte Manschetten zum Hineinschlüpfen. Die e l ast i schen Bänder sind vorzugsweise so gewoben, dass sie sich durch verschiedene Elastizitätsstärken der Ränder auch in der Bandebene krummziehen lassen. Solche Bänder sind in verschiedenen Stärken im Handel erhältlich.Furthermore, the embodiment shown captivates with a relatively simple structure that does not involve any manufacturing problems. As FIG. 4 shows, this knee brace consists of two thigh cuffs 20, 21, which are shown here in an open version with fastening straps 25, and of two crossed diagonal straps 22 and 23 attached to the thigh cuffs. The thigh cuffs are generally for upper and Lower legs of different sizes, either adjustable, e.g. by means of the practical Velcro fastener, or fixed, by undivided ones Slip on cuffs. The elastic bands are preferably woven in such a way that they can also be bent in the plane of the band due to the different elastic strengths of the edges. Such tapes are commercially available in various strengths.
Die in Figur 4 gezeigte Kniebandage hat für den Tragkomfort ausserdem noch folgende Vorteile. Zwischen der Kreuzungsstelle der Diagonalbänder und der Schenkelmanschette ist eine freie Stelle P als Patellaführung für die Kniescheibe vorhanden. Die Kniescheibe ist, nebst dass sie besser geführt ist, aeif diese Weise keinem Druck in Richtung Gelenk ausgesetzt ist, was bei den üblichen Kniebandagen durchaus der Fall ist. Dieser sonst unvermeidliche Druck wird bei Schiupfbandagen bspw. durch lockeres Stricken möglichst gering gehalten, bei der Kniebandage gemäss Erfindung ist dies nicht mehr nötig. Ferner ist die erfindungsgemässe Kniebandage im Bereich der Kniekehle vollständig offen, sodass auch bei maximaler Durchbeugung, bspw. in der Hocke, keine störende Faltenbildung zu befürchten ist.The knee brace shown in Figure 4 also has the following advantages for comfort. Between the point of intersection of the diagonal bands and the thigh cuff there is a free point P as a patella guide for the patella. In addition to being better guided, the kneecap is not exposed to pressure in the direction of the joint, which is quite the case with the usual knee supports. This otherwise unavoidable pressure is kept as low as possible in the case of Schiupf bandages, for example by loose knitting, in the knee bandage according to the invention this is no longer necessary. Furthermore, the knee brace according to the invention is completely open in the area of the hollow of the knee, so that even with maximum deflection, for example when crouching, there is no fear of any annoying wrinkling.
Figur 5 zeigt die Kniebandage von Fi gur 4 i n se i ner of fenen Form . Es i st unmi t te l bar e i nzusehen, dass hier, trotz anspruchsvoller topologischer Verhältnisse der um das bewegte Kniegelenk anliegenden Bandage, einfache herstellungstechnische Verhältnisse vorliegen. Die ganze Bandage kann gemäss dieser Ausführungsform im Flachnähverfahren gefertigt werden. Die Schenkelmanschetten 20 und 21 werden in der gewünschten den Unter- und Oberschenkeln angepassten Länge zugeschnitten. Die Längs-Elastizität des Bandes ist bspw. an den Aussense iten 31,32 geringer, damit sich die Manschetten dem konischen Verlauf der Schenkel entsprechend anpassen. Ebenso kann man mit den Diagonalbändern 22,23 verfahren, die übereinandergelegt gekreuzt an den Stellen 28 mit den Sehen- ke lmansche t ten vernäht sind und bspw. an den Seiten 33 einer geringere Elastizität aufweisen als an der anderen Parallelseite. Auf diese Weise schmiegen sich die Diagonalbänder von unten her sanft an die Kniescheibe ohne sie hoch zu drücken.FIG. 5 shows the knee brace of FIG. 4 in its open form. It is unmistakable to see that, despite the challenging topological conditions of the bandage around the moving knee joint, there are simple manufacturing conditions. According to this embodiment, the entire bandage can be manufactured using the flat sewing method. The thigh cuffs 20 and 21 are cut to the desired length adapted to the thighs and thighs. The longitudinal elasticity of the band is, for example, less on the outer sides 31, 32 so that the cuffs adapt to the conical shape of the legs. The same can be done with the diagonal bands 22, 23, which, in a superimposed manner, are crossed at points 28 with the eyes. not all of the seams are sewn and, for example, have a lower elasticity on the sides 33 than on the other parallel side. In this way, the diagonal bands gently nestle against the kneecap without pushing it up.
Die Schenkelmanschetten sind an ihren Enden offen und mit Befestigungsmitteln 2ό,27 versehen. Sehr empfehlenswert sind Bänder mit dem bekannten Klettenverschluss. Auf diese Weise ist die Schenkelmanschette nicht nur mit einem flachen schmiegsamen Versehluss versehen, sondern auch noch in ihrem Umfang je nach normaler oder sportlicher Belastung einstellbar. Ganz nebenbei ist der Klettenverschluss leicht zu schli essen und leicht zu öffnen und seine Haltekraft ist nachweislich erprobt. In Figuir 5 sind solche, einfach mit Nähten 29 befestigte Klettenverschlusspaare 2ό,27 abgebildet, wobei es offen bleibt, auch andere Befestigungsmittel wie Schnallen etc. zu verwenden.The thigh cuffs are open at their ends and provided with fasteners 2ό, 27. Tapes with the well-known Velcro fastener are highly recommended. In this way, the thigh cuff is not only provided with a flat, supple miss, but also its size can be adjusted according to normal or sporting loads. Incidentally, the Velcro fastener is easy to eat and easy to open and its holding power has been proven. Such Velcro fastener pairs 2etten, 27, simply fastened with seams 29, are shown in FIG. 5, wherein it remains open to use other fastening means such as buckles, etc.
Figur 6 zeigt schli esslich eine Ausführungsform, bei der eine der Oeffnungen P für die Patella so ausgestaltet ist, dass mit einfachen zusätzlichen Mitteln eine wirksame (verstärkte) Patellaführung möglich ist. Mit einem im Bereich der Oeffnung P angeordneten Ring 35, bspw. aus Gummi, Silikon o.ä. bestehend, der mit, hier an der Ober- und Unterschenkelmanschette befestigten, Bändern gehalten ist, lässt sich die verstärkte Patellaführung recht einfach realisieren. Figur 6 zeigt noch eine vorteilhafte Ausgestaltung der Kniebandage mit einer längeren Oberschenkelmanschette und einer kürzeren Unterschenkelmanschette, wie dies bei den üblichen anatomischen Gegebenheiten des Beines angebracht ist. Als Verschlussmittel sind hier Oesen 38 gezeichnet, in welche die Bandenden 39 eingeschlauft werden können. Die Bemessungen der Länge der Diagonalbänder und der Kreuzungswinkel richten sich nach anatomischen Erfordernissen aus. Auch ist es möglich neben einer gemäss statistischen anatomischen Abmessungen ausgelegten "Standard-Kniebandage", die mehr zur Prophylaxe gedacht ist, mit Hilfe der gezeigten Projektionsmethode auch spezielle posttraumatische Laxitäten individuell auszugleichen. Die Führung von weiteren Bändern zwischen den Schenkelmanschetten, bewirkt zusätzliche Hilfs- funktionen und die spezielle Ausgestaltung der verwendeten Bänder bezüglich Schnitt und bezüglich Elastizitätsgradienten im Band, öffnet weitere Möglichkeiten zur verfeinerten Ausgestaltung der Kniebandage gemäss Erfindung. FIG. 6 finally shows an embodiment in which one of the openings P for the patella is designed in such a way that effective (reinforced) patella guidance is possible with simple additional means. With a ring 35 arranged in the area of the opening P, for example made of rubber, silicone or the like. existing, which is held here with straps attached to the upper and lower leg cuff, the reinforced patella guide can be realized quite easily. Figure 6 shows an advantageous embodiment of the knee brace with a longer thigh cuff and a shorter lower leg cuff, as is appropriate in the usual anatomical conditions of the leg. Eyes 38 are drawn here as closure means, into which the band ends 39 can be looped. The dimensions of the length of the diagonal bands and the crossing angle are based on anatomical requirements. In addition to a "standard knee brace" designed according to statistical anatomical dimensions, which is intended more for prophylaxis, it is also possible to individually compensate for special post-traumatic laxities using the projection method shown. The guiding of additional ligaments between the thigh cuffs, brings about additional auxiliary functions and the special design of the ligaments used with regard to the cut and elastic gradients in the ligament, opens up further possibilities for refining the knee support according to the invention.
