In this study, our aim was to reveal the effect of the medial femoral offset aimer usage through the femoral tunnel entry and exit points and the tunnel length during femoral tunnel drilling in arthroscopic anterior cruciate ligament (ACL) reconstruction.
One hundred patients who underwent arthroscopic single-bundle ACL reconstruction were included in the study. Group 1 consisted of 50 patients who underwent femoral tunnel drilling using a medial portal offset aimer device, while Group 2 consisted of 50 patients who were operated on using the freehand technique. Both groups were compared in terms of femoral tunnel and graft tunnel lengths, femoral tunnel angle in the coronal plane, and the location of the femoral tunnel entry and exit points.
The mean femoral tunnel and graft tunnel lengths were significantly longer in Group 2 ( = 0.000). There was no significant difference in terms of localization of the femoral tunnel entry point in both the axial and sagittal planes. The tunnel exit point was located significantly more posterior in Group 1 in the axial plane ( = 0.028). There was no significant difference in terms of the coronal plane femoral tunnel angle between the two groups.
In arthroscopic ACL reconstructions, more successful results may be obtained with the freehand technique compared to drilling with a femoral offset aimer. For an experienced orthopedic surgeon, using a medial portal offset aimer device during femoral tunnel drilling does not seem necessary.

在本研究中，我们的目的是通过关节镜下前交叉韧带（ACL）重建术中股骨隧道钻孔时的股骨隧道入口和出口点以及隧道长度，揭示股骨内侧偏移瞄准器使用的效果。
100例行关节镜下单束ACL重建的患者纳入本研究。第1组由50例使用内侧入路偏移瞄准器装置进行股骨隧道钻孔的患者组成，而第2组由50例采用徒手技术进行手术的患者组成。比较两组在股骨隧道和移植物隧道长度、冠状面股骨隧道角度以及股骨隧道入口和出口点位置方面的情况。
第2组的平均股骨隧道和移植物隧道长度明显更长（=0.000）。在轴向和矢状面，两组股骨隧道入口点的定位无显著差异。在轴向平面，第1组的隧道出口点明显更靠后（=0.028）。两组在冠状面股骨隧道角度方面无显著差异。
在关节镜下ACL重建中，与使用股骨偏移瞄准器钻孔相比，徒手技术可能获得更成功的结果。对于经验丰富的骨科医生来说，在股骨隧道钻孔时使用内侧入路偏移瞄准器装置似乎没有必要。
