Abrégé
(EN)
 An artificial knee joint implant with which it is possible to increase the tolerance for rotational movement together with increasing the binding force of the femoral component and tibial component in the longitudinal and lateral directions of a patient. An artificial knee joint implant 1 has a femoral component 2 fixed to the distal portion 102 of the femur 101 of a patient, and a tibial component 3 fixed to the proximal portion 104 of the tibia 103 of the patient. The femoral sliding surfaces 20A, 20B of the femoral component 2 and the tibial sliding surfaces 23A, 23B of the tibial component each include regions where the radius of curvature varies in accordance with progression along a prescribed direction.

La présente invention concerne un implant d'articulation de genou artificiel permettant d'augmenter la tolérance au mouvement de rotation et la force de liaison du composant fémoral et du composant tibial dans les directions longitudinale et latérale d'un patient. Un implant d'articulation de genou artificiel 1 comporte un composant fémoral 2 fixé à la partie distale 102 du fémur 101 d'un patient, et un composant tibial 3 fixé à la partie proximale 104 du tibia 103 du patient. Les surfaces de coulissement fémorales 20A, 20B, du composant fémoral 2 et les surfaces de coulissement tibiales 23A, 23B du composant tibial comprennent chacune des régions dans lesquelles le rayon de courbure varie en fonction d'une progression le long d'un direction prescrite.

 人工膝関節インプラントにおいて、患者の前後方向および左右方向における大腿骨コンポーネントと脛骨コンポーネントの拘束力を大きくできるとともに、回旋運動の許容度を大きくできるようにする。 人工膝関節インプラント1は、患者の大腿骨101の遠位部102に固定される大腿骨コンポーネント2と、患者の脛骨103の近位部104に固定される脛骨コンポーネント3と、を有する。大腿骨コンポーネント2の大腿骨摺動面20A,20B、および、脛骨コンポーネント3の脛骨摺動面23A,23Bは、何れも、所定方向に沿って進むに従い曲率半径が変化する領域を含んでいる。
