Abstract

La présente invention concerne un appareil orthopédique d'articulation du genou dans lequel des cadres de l'appareil orthopédique d'articulation du genou peuvent être montés en contact étroit avec la surface de fixation du fémur et la surface de fixation du tibia même si la surface de fixation du fémur et la surface de fixation du tibia ne sont pas parallèles l'une à l'autre, et les cadres de l'appareil orthopédique d'articulation du genou peuvent être fixés en contact étroit avec le fémur et le tibia, le poids corporel pouvant être supporté de la même manière même si la surface fixée sur l'appareil orthopédique du fémur et la surface fixée sur l'appareil orthopédique du tibia ne sont pas situées sur le même plan en raison de formes anormales du fémur et du tibia. De plus, l'appareil orthopédique d'articulation de genou selon la présente invention est fixé entre le fémur et le tibia et, conformément, présente l'avantage de permettre un mouvement tridimensionnel de l'articulation du genou d'un patient chirurgical, etc., en aidant le patient chirurgical, etc. à réaliser en douceur un mouvement de rotation de l'articulation du genou dans une amplitude angulaire prédéterminée ainsi qu'un mouvement de fléchissement de l'articulation du genou tout en maintenant des intervalles d'articulation constants.
