    摘要： A surgical apparatus comprising a first distraction mechanism, a second distraction mechanism, and a third distraction mechanism. The surgical apparatus is configured to be placed in a joint of the musculoskeletal system to precisely separate the first bone from the second bone to support one or more bone cuts for installing a prosthetic joint. The first distraction mechanism simultaneously changes a height of a first side and a second side of the joint. The change in height is equal on the first and second sides. The second distraction mechanism changes the height on the first side of the joint but not the second side. The third distraction mechanism changes the height of the second side of the joint but not the first side. The surgical apparatus further includes at least one module to measure loading applied by the joint to the surgical apparatus.

    摘要： A knee bone cut system and method is disclosed. The knee bone cut system supports cutting an anterior portion of a distal end of a femur. The system comprises a sensored insert, a femoral rotation guide, and a remote system to receive and display sensor data. The sensored insert provide data related to load magnitude, position of load, and leg position. The femoral rotation guide has moveable condyles to adjust condyle position in a rapid manner. A pinch mechanism and lock mechanism respectively move the condyles into contact with the sensored insert. Moreover, the femoral rotation guide can be loaded similar to a final installed insert over a range of motion. For example, the patella can be placed on the femoral rotation guide allowing the patella to load the sensored insert. The femoral insert guide includes guide holes that are used in conjunction with a bone cutting jig.

    摘要翻译： 公开了一种膝骨切割系统和方法。 膝骨切割系统支撑切割股骨远端的前部。 该系统包括感测插入件，股骨旋转引导件和用于接收和显示传感器数据的远程系统。 感应插入物提供与负载大小，负载位置和腿位置有关的数据。 股骨旋转引导件具有可移动的髁以便以快速方式调节髁位置。 夹紧机构和锁定机构分别使髁与感应插入物接触。 此外，股骨旋转引导件可以在一定范围的运动中类似于最终安装的插入件被加载。 例如，髌骨可以放置在股骨旋转引导件上，允许髌骨加载感觉插入物。 股骨插入引导件包括与骨切割夹具一起使用的引导孔。
