Abstract

L'invention concerne un implant fémoral (1) pour prothèse uni-compartimentale du genou, ledit implant comprenant une surface interne d'ancrage (2) dans un condyle d'un fémur, et une surface externe fonctionnelle (4) destinée à être en contact avec une partie d'usure de la prothèse, ladite surface externe fonctionnelle (4) présentant : - une surface fonctionnelle distale (4b) définie par la révolution d'un arc de cercle (6) autour de son diamètre ; - une surface fonctionnelle postérieure (4a), prolongeant la surface fonctionnelle distale (4b), et définie par la révolution de l'arc de cercle (6) autour d'un axe parallèle à une corde (7) reliant deux extrémités de l'arc de cercle (6) et distinct du diamètre ; la surface fonctionnelle distale (4b) présente une section en arc de cercle (6) et présente une ligne de courbure médiane (8) inscrite dans un plan incliné (P1) par rapport au plan sagittal (P). Selon l'invention, la corde (7) reliant deux extrémités de l'arc de cercle (6) de la section de la surface fonctionnelle distale (4b) est orthogonale au plan incliné (P1).
