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).
(ZH) 一种人工膝关节(1)用的胫骨组件(3),其包括基座(4),该基座(4)固定于胫骨的上方切除面,在上表面形成有分别承受股骨组件(2)的内侧髁(22)和外侧髁(23)的内侧滑动面(43)和外侧滑动面(44)。在基座(4)形成有向后开口的凹陷(31),该凹陷(31)用于避免与后十字韧带的冲突。在内外方向上,凹陷(31)的中心比基座(4)的中心向内方靠近。
