要約
(EN) A tibial component (3) for an artificial knee joint (1) comprises a base (4) which is fixed to an upper cut surface of the tibia and has, on the upper surface, an medial sliding surface (43) and a lateral sliding surface (44) which receive a medial condyle (22) and a lateral condyle (23) of a femoral component (2), respectively. In the base (4), a recess (31) opening backward is formed to avoid interference with the posterior cruciate ligament. In the mediolateral direction, the center of the recess (31) is offset inward from the center of the base (4).
(FR) La présente invention concerne un composant tibial (3) pour une articulation de genou artificiel (1) qui comprend une base (4) qui est fixée à une surface de coupe supérieure du tibia et présente, sur la surface supérieure, une surface coulissante médiale (43) et une surface coulissante latérale (44) qui reçoivent respectivement un condyle médial (22) et un condyle latéral (23) d'un composant fémoral (2). Dans la base (4), un évidement (31) est formé avec une ouverture vers l'arrière pour éviter des interférences avec le ligament croisé postérieur. Dans la direction médio-latérale, le centre de l'évidement (31) est décalé vers l'intérieur par rapport au centre de la base (4).
(JA) 人工膝関節(1)用の脛骨コンポーネント(3)は、脛骨の上方切除面に固定される、大腿骨コンポーネント(2)の内顆(22)および外顆(23)をそれぞれ受ける内側摺動面(43)および外側摺動面(44)が上面に形成されたベース(4)を含む。ベース(4)には、後十字靭帯との干渉を回避するための後ろ向きに開口する窪み(31)が形成されている。内外方向において、窪み(31)の中心は、ベース(4)の中心よりも内方に寄せられている。
