The goal of this preliminary report was to show the use of novel Ultrasound (US) technology for anterior cruciate ligament (ACL) reconstruction surgery and evaluate its feasibility for the creation of a rectangular femoral bone tunnel during an arthroscopic procedure in a human cadaver model.
Two fresh frozen human cadaver knees were prepared for arthroscopic rectangular femoral tunnel completion using a prototype US device (OLYMPUS EUROPA SE & CO. KG). The desired rectangular femoral tunnel was intended to be located in the femoral anatomical ACL footprint. Its tunnel aperture was planned at 10 × 5 mm and a depth of 20 mm should be achieved. For one knee, the rectangular femoral tunnel was realized without a specific cutting guide and for the other with a 10 × 5 mm guide. One experienced orthopedic surgeon performed the two procedures consecutively. The time for femoral tunnel completion was evaluated. CT scans with subsequent three-dimensional image reconstructions were performed in order to evaluate tunnel placement and configuration.
In the two human cadaver models the two 10 × 5x20mm rectangular femoral tunnels were successfully completed and located in the femoral anatomical ACL footprint without adverse events. The time for femoral tunnel completion was 14 min 35 s for the procedure without the guide and 4 min 20 s with the guide.
US technology can be used for the creation of a rectangular femoral bone tunnel during an arthroscopic ACL reconstruction procedure. The use of a specific cutting guide can reduce the time for femoral tunnel completion. Additional experience will further reduce the time of the procedure.
本初步报告的目的是展示新型超声（US）技术在前交叉韧带（ACL）重建手术中的应用，并评估其在人体尸体模型的关节镜手术中创建矩形股骨骨隧道的可行性。
使用原型超声设备（OLYMPUS EUROPA SE & CO. KG）对两具新鲜冷冻的人体尸体膝关节进行准备，以完成关节镜下矩形股骨隧道。所需的矩形股骨隧道旨在位于股骨解剖学ACL足迹处。其隧道孔径计划为10×5毫米，深度应达到20毫米。对于一个膝关节，在没有特定切割导向器的情况下实现了矩形股骨隧道，而另一个则使用了10×5毫米的导向器。一位经验丰富的骨科医生连续进行了这两个手术。评估了股骨隧道完成的时间。进行了CT扫描及后续的三维图像重建，以评估隧道的位置和形态。
在两个人体尸体模型中，成功完成了两个10×5×20毫米的矩形股骨隧道，并位于股骨解剖学ACL足迹处，无不良事件发生。无导向器的手术中股骨隧道完成时间为14分35秒，使用导向器的手术中为4分20秒。
超声技术可用于关节镜下ACL重建手术中创建矩形股骨骨隧道。使用特定的切割导向器可减少股骨隧道完成时间。更多经验将进一步缩短手术时间。
