Title (EN) KNEE PROSTHESIS
(FR) PROTHÈSE DE GENOU
Abstract:
(EN) A knee prosthesis having a femoral component (200) with two condyles (201,202), an opening (205) disposed between the two condyles, and a tibial component (100) having bearing surfaces (101,102) to engage and support each of the femoral component condyles. Moving the femoral and tibial components in flexion from about 0° to about 165° causes medial pivot rotation of the femoral component upon the tibial component. Rotation may be caused by interaction between an asymmetrical cam (210) extending between the femoral condyles and a post (110) disposed between the bearing surfaces and extending superior from the tibial component. Rotation may alternatively be caused by asymmetrical medial and lateral condyles which translate posteriorly upon respective medial and lateral bearing surfaces at disparate rates, without a femoral cam, a tibial post, or a post/cam contact surface. Embodiments of the knee prosthesis may be used in cruciate-substituting or cruciate- retaining procedures. Embodiments of the knee prosthesis may also prevent roll forward.
(FR) La présente invention concerne une prothèse de genou possédant un composant fémoral avec deux condyles, une ouverture disposée entre les deux condyles, et un composant tibial doté de surfaces d'appui permettant de venir en contact et de soutenir chacun des condyles de composant fémoral. Le déplacement des composants fémoral et tibial en flexion entre environ 0 ° et environ 165 ° entraîne la rotation pivotante médiale du composant fémoral sur le composant tibial. Ladite rotation peut être entraînée par l'interaction entre une came asymétrique s'étendant entre les condyles fémoraux et un montant disposé entre les surfaces d'appui et s'étendant au-dessus du composant tibial. La rotation peut alternativement être provoquée par des condyles latéral et médial asymétriques qui réalisent une translation de manière postérieure sur des surfaces d'appui médiale et latérale respectives à des rythmes disparates, sans came fémorale, montant tibial, ou surface de contact de montant/de came. Dans certains modes de réalisation, la prothèse de genou peut être utilisée dans des procédures de remplacement du ligament croisé ou de conservation du ligament croisé. Dans certains modes de réalisation, la prothèse de genou peut également empêcher le roulement vers avant.
