Femoral tunnel preparation during the anterior cruciate ligament reconstruction is a technically demanding step. The anteromedial (AM) portal technique necessitates knee hyperflexion during the femoral tunnel reaming. In a hyperflexed knee, the arthroscopic visualization of the laser markings on the femoral tunnel reamer becomes obscured. Thus, the calculation of the depth of the femoral tunnel becomes difficult. Our technique helps in femoral tunneling reliably without the need for arthroscopic visualization using the AM portal as a reference point to calculate the depth while drilling. This technique can be performed without the need for a second assistant to hold the arthroscope. Furthermore, this technique does not require any specific instruments, and there is no obligation for an additional incision.
在进行前交叉韧带重建时，股骨隧道的制备是一个技术要求较高的步骤。前内侧（AM）入路技术在股骨隧道扩孔时需要膝关节极度屈曲。在极度屈曲的膝关节中，股骨隧道扩孔器上激光标记的关节镜视野会变得模糊。因此，股骨隧道深度的计算变得困难。我们的技术有助于可靠地进行股骨隧道操作，无需以AM入路作为钻孔时计算深度的参考点进行关节镜视野观察。该技术无需第二名助手手持关节镜即可完成。此外，该技术不需要任何特殊器械，也无需额外切口。
