    Abstract: Certain versions generally provide an improved tibial base member (for example, but not limited to, 10) comprising keel portions (for example, but not limited to, 14a, 14b, 14c) that allow one or both cruciate ligaments to be preserved. Other versions provide improved lateral and/or medial inserts (for example, but not limited to, 110, 210) having a mesial lip (for example, but not limited to, 118, 128) that helps relieve and/or prevent impingement between the femoral component (for example, but not limited to, 400) and the tibial eminence. Other versions provide improved femoral components (for example, but not limited to, 400) having various chamfers (for example, but not limited to, 404, 410, 470) to provide additional clearance with respect to the tibial eminence and posterior cruciate ligament without decreasing bone coverage.

    Abstract translation: 某些型式通常提供一种包括龙骨部分（例如但不限于，14a，14b，14c）的改进的胫骨基座部件（例如但不限于10），其允许一个或多个 两个十字韧带都要保存。 其他版本提供了具有中唇（例如但不限于118,128）的改进的侧向和/或中间插入物（例如但不限于110,210），其有助于缓解和/或防止 股骨组件（例如但不限于400）和胫骨隆凸。 其他版本提供了具有各种倒角（例如但不限于404,410,470）的改进的股骨部件（例如但不限于400），以相对于胫骨隆凸和后十字韧带提供额外的间隙，而没有 减少骨骼覆盖率。

    Abstract: A knee system includes a knee prosthesis having a tibial arrangement including a tibial tray configured for attachment to a surgically-prepared surface of a proximal end of the tibia. The tibial arrangement also includes a tibial insert system including a lateral tibial insert and a medial tibial insert. One of the inserts is configured to move in a generally anterior-posterior direction relative to the tibial tray, and the other insert is configured for fixed attachment to the tibial tray. The knee prosthesis also includes a femoral component configured for attachment to a surgically-prepared surface of a distal end of a femur. The femoral component and tibial inserts each have articular surfaces configured to contact and articulate relative to each other during extension and flexion of the knee.

    Abstract translation: 膝系统包括具有胫骨布置的膝关节假体，所述胫骨布置包括构造成用于附接到胫骨近端的手术准备的表面的胫骨托。 胫骨布置还包括胫骨插入系统，其包括外侧胫骨插入件和内侧胫骨插入件。 插入件中的一个被配置为相对于胫骨托大致前后方向移动，另一个插入件构造成用于固定附接到胫骨托盘。 膝关节假体还包括构造成附接到股骨远端的手术准备表面的股骨部件。 股骨部件和胫骨插入物各自具有构造成在膝盖的伸展和弯曲期间相对于彼此接触和铰接的关节表面。

    Abstract: A tibial tray system includes a tibial tray configured for attachment to a surgically-prepared surface of the proximal end of the tibia. The tibial tray includes a track disposed in a generally A-P direction. The tibial tray system also includes a spline configured to engage the track and to be positionable in at least one location along the track. The spline includes a bearing surface that is configured to contact a femoral component of the knee prosthesis to guide movement of the femoral component during extension and flexion of the knee.

    Abstract translation: 胫骨托盘系统包括构造成附接到胫骨近端的手术准备的表面的胫骨托。 胫骨托包括沿A-P方向设置的轨道。 胫骨托盘系统还包括构造成接合轨道并且可沿着轨道的至少一个位置定位的花键。 花键包括支撑表面，其构造成接触膝关节假体的股骨部件以引导股骨部件在膝盖的伸展和屈曲期间的移动。
