    • A system and process for performing orthopedic surgery is provided that uses a tibial trial system in total knee arthroplasty for assessing optimal internal-external rotation and posterior tibial slope, and for measuring the rotation of a tibial trial throughout flexion-extension to determine and mark the best position for the final tibial component. The tibial trial system determines the internal-external location on a patient specific basis with improved component placement well within the present manual methods. One particular advantage to the tibial trial system is to assess the natural internal-external rotation that the tibial component will experience relative to the femoral component during flexion-extension as opposed to simply recording and balancing forces on a static tibial trial. The invention disclosed herein may also be adapted to be used with a computer assisted surgical device. Such surgical devices include active, semi-active, and haptic devices as well as articulating drill and saw systems.
    • 提供了一种用于执行整形外科手术的系统和过程,其使用全膝关节置换术中的胫骨试验系统来评估最佳的内外旋转和后胫骨坡度,并且用于在屈曲伸展期间测量胫骨试验的旋转以确定和标记 最终胫骨部件的最佳位置。 胫骨试验系统在目前的手动方法中确定了患者特定基础上的内部和外部位置,改善了组件位置。 胫骨试验系统的一个特别优点是评估胫骨部件在屈曲伸展期间相对于股骨部件将经历的自然内外旋转,而不是在静态胫骨试验上简单记录和平衡力。 本文公开的发明也可适用于与计算机辅助手术装置一起使用。 这种手术装置包括活动的,半活动的和触觉的装置以及铰接钻和锯系统。
