Abstract

The object of these prostheses is to replace injured menisci following surgical removal. The invention relates to prostheses composed of two elements: - a semi-rigid central core perforated with holes 1 at its periphery for suturing it and other holes 2 for making it flexible and for its incorporation into the body; - a flexible peripheral cover woven from the same biocompatible material as the central core (high-density polyethylene or derivatives) and unattached to this core. These prostheses are unattached, integrally reconstructing the destroyed meniscal cartilage. Their two-component structure allows relative sliding. They can thus be integrated biologically into the body.

Description

La présente invention est une prothèse chirurgicale synthétique méniscale des genoux
Elle a pour but de remplacer les ménisques lésés ou détruits ayant subi une ablation chirurgicale.The present invention is a synthetic meniscal knee surgical prosthesis
Its purpose is to replace injured or destroyed menisci that have undergone surgical removal.

Il s'agit d'une prothèse composée de deux éléments
Un noyau central semi-rigide,
Une enveloppe périphérique souple engainant le noyau central
mais sans attache aveclui. It is a prosthesis composed of two elements
A semi-rigid central core,
A flexible peripheral envelope covering the central core
but without attachment to him.

Ces deux éléments sont constitués du même matériau biocompatible (Polyéthylène de haute densité ou d'un matériau correspondant)
La présente invention sera mieux comprise par la description d'un mode de réalisation préférentiel en référence au dessin annexé dans lequel
- L'élément central semi-rigide (FIG 1) en forme de croissant (plus arrondi pour le ménisque externe) et représentant exactement la morphologie des ménisques naturels
Est perforé de trous périphériques de fixation (1) pour suturer le ménisque prothétique å la capsule articulaire, répartis tous les 4 mm.These two elements are made of the same biocompatible material (High density polyethylene or a corresponding material)
The present invention will be better understood from the description of a preferred embodiment with reference to the appended drawing in which
- The semi-rigid central element (FIG 1) in the shape of a crescent (more rounded for the external meniscus) and representing exactly the morphology of the natural menisci
Perforated with peripheral fixation holes (1) to suture the prosthetic meniscus to the joint capsule, distributed every 4 mm.

et d'orifices plus larges de forme rectangulaire (2). Ils permettent une plus grande souplesse et une communication entre les parties supérieure et inférieure de la prothèse autorisant une éventuelle réhabitation de celle-ci. Cette réhabitation peut être favorisée par l'inclusion d'éléments favorisant la régénération biologique (collagène par exemple). and wider rectangular holes (2). They allow greater flexibility and communication between the upper and lower parts of the prosthesis allowing for possible rehabitation thereof. This rehabitation can be favored by the inclusion of elements promoting biological regeneration (collagen for example).

- L'élément périphérique (FIG 2)
Fait d'une structure tissée dans la même matière que le noyau central dont elle épouse exactement la forme mais en restant libre et qui peut etre de deux ou trois épaisseurs (3)
Cet élément périphérique (3) confère à la prothèse une pro priété d'autoglissement et donc de protection de la surface cartilagineuse fémorale.- The peripheral element (FIG 2)
Made of a woven structure in the same material as the central core which it exactly matches the shape but remaining free and which can be two or three thicknesses (3)
This peripheral element (3) gives the prosthesis a property of self-sliding and therefore of protection of the femoral cartilage surface.

Cette prothèse fémorale remplit donc les conditions suivantes
- être souple pour s'adapter au relief anatomique essentiellement fémoral lors des mouvements de celui-ci.This femoral prosthesis therefore fulfills the following conditions
- be flexible to adapt to the essentially femoral anatomical relief during its movements.

- ne pas traumatiser le cartilage fémoral : la semi-souplesse de la prothèse doublée du glissement de l'enveloppe externe devrait limiter au maximum les risques d'usure. - not to traumatize the femoral cartilage: the semi-flexibility of the prosthesis doubled by the sliding of the external envelope should limit as much as possible the risks of wear.

- permettre une réhabitation biologique du ménisque prothétique grace au tissage externe perméable : pénétration de fibrine et de dépôts protéiniques, augmentée au besoin par l'inclusion de collagène dans les trous du noyau central. - allow a biological rehabitation of the prosthetic meniscus thanks to the permeable external weaving: penetration of fibrin and protein deposits, increased if necessary by the inclusion of collagen in the holes of the central nucleus.

Les dessins annexés illustrent l'invention
La FIG 1 représente le noyau semi-rigide épousant la forme des
ménisques naturels et positionnés sur la surface
supérieure du tibia (en pointillé)
Il est perforé : de trous périphériques pour la suture (1)
de trous plus larges (2) rectangulaires pour
assouplir la prothèse et favoriser sa réhabi
tation
Ces trous apparaissent aussi sur la coupe.The accompanying drawings illustrate the invention
FIG 1 represents the semi-rigid core conforming to the shape of
natural menisci positioned on the surface
upper shin (dotted)
It is perforated: with peripheral holes for suturing (1)
larger rectangular holes (2) for

tation
These holes also appear on the cut.

La FIG 2 représente l'élément externe (3) qui épouse exactement
la forme du noyau central tout en restant libre de lui FIG 2 represents the external element (3) which exactly matches
the shape of the central core while remaining free from it
