Abstract

Una prótesis de articulación de rodilla que tiene un componente femoral que incluye un par de partes condilares espaciadas entre sí lateralmente, cada una de las cuales tiene una superficie externa que está curvada con suave convexidad en sentido anteroposterior para adaptarse en general al perfil lateral de un cóndilo femoral anatómico, y curvada con suave convexidad lateralmente en toda su extensión antero-posterior, y una parte intercondilar similar a una caja que une a las partes condilares; y un componente tibial que incluye una parte de plataforma similar a una placa que tiene, en su superficie superior, un par de concavidades espaciadas entre sí lateralmente, cada una de las cuales está destinada a recibir en relación de alojada o encajada a una de las partes condilares del componente femoral, y una columna que se extiende por la parte superior desde la superficie de la plataforma, entre las concavidades, para ser reducida en la parte intercondilar del componente femoral, en cuya prótesis la parte intercondilar define un rebajo que se abre inferiormente hacia el componente tibial e incluye paredes laterales espaciadas entre sí, siendo plana una pared superior que une las paredes laterales y estando dispuesta en general paralela a un plano de referencia perpendicular al eje nominal de la pierna extendida, y habiendo prevista una parte seguidora de leva en el extremo posterior de la pared superior, que tiene una superficie seguidora curvada con convexidad transversalmente; y la columna tibial tiene una superficie posterior que tiene una parte de leva curvada con concavidad adyacente a la unión entre la columna y la superficie de la plataforma, estando la parte de leva en la columna destinada a establecer aplicación con la superficie seguidora en la parte intercondilar al flexionar la pierna, y teniendo el fémur tendencia a trasladarse anteriormente con relación a la tibia y a forzar a los zonas de contacto entre las superficies condilares femorales del componente femoraly las concavidades del componente tibial posteriormente, al aumentar el grado de flexión de la pierna.
