The ACL TightRope RT (Arthrex, Naples, FL) is a recently introduced fixation device. The adjustable graft loop allows the surgeon some freedom in terms of the length of the femoral socket, eliminates the need for bothersome intraoperative calculations for selecting loop length, ensures that the socket is completely filled with graft, and provides the possibility of tensioning the graft even after graft fixation. However, the device can be associated with the same complications that have been described with EndoButton (Smith & Nephew Endoscopy, Andover, MA) fixation. For example, in our experience, sometimes the button of the TightRope RT may not flip, may become jammed inside the femoral canal, or may flip in the substance of the vastus lateralis. To prevent this, we have introduced 2 additional steps in our procedure: (1) direct visualization of the TightRope RT button in the femoral socket with the arthroscope during its passage and (2) a controlled push directly on the button with the help of a guide pin. Thus proper seating of the button is ensured by direct visualization and the crucial push helps in flipping and seating of the button.
ACL TightRope RT(美国佛罗里达州那不勒斯市的Arthrex公司生产)是一种最近推出的固定装置。可调节的移植物环使外科医生在股骨套接长度方面有一定的自由度,无需在术中进行繁琐的计算来选择环的长度,确保套接完全被移植物填满,并且即使在移植物固定后也能对移植物进行张紧。然而,该装置可能会出现与EndoButton(美国马萨诸塞州安多弗市的Smith & Nephew Endoscopy公司生产)固定相关的相同并发症。例如,根据我们的经验,有时TightRope RT的纽扣可能无法翻转,可能会卡在股管内,或者可能在股外侧肌实质内翻转。为防止这种情况发生,我们在手术过程中增加了两个步骤:(1)在TightRope RT纽扣穿过时,通过关节镜直接观察其在股骨套接内的情况;(2)借助导针直接对纽扣进行控制性推压。这样,通过直接观察可确保纽扣正确就位,关键的推压有助于纽扣翻转并就位。
