To investigate the effect of the position of the femoral endobutton on knee function in the posterior cruciate ligament reconstruction (PCLR).
A retrospective study was conducted to analyze 96 patients who underwent single-bundle reconstruction of posterior cruciate ligament (PCL) in our hospital from January 2020 to June 2023. The patients were divided into three groups according to the position of the endobutton on the lateral knee radiography. The first group is the position of endobutton in front of the lateral cortex of the femur, the second group is the position of endobutton in back of the lateral cortex of the femur, and the third group is the position of endobutton behind the femur. Knee Lysholm score, International Knee Documentation Committee (IKDC) Evaluation, Tegner Activity Scale, knee flexion angle and postoperative complication rate of the three groups were compared to evaluate whether there were statistical differences among the three groups.
There were 39 patients in group 1, 46 patients in group 2, and 11 patients in group 3. The mean Lysholm Knee Scores of the group 1 was 91.77, 92.17 in group 2, and 90.36 in group 3. The mean IKDC Evaluation of group 1 was 90.48, 92.41 in group 2, and 93.00 in group 3. Tegner Activity Level was 5.69 in group 1, 5.72 in group 2, and 5.45 in group 3. The mean flexion degree was found as 125° in patients in group1, 127° in group 2, and 122° in group 3. There was no statistically significant difference between Lysholm Knee Scores (p = 0.434), IKDC (p = 0.068), Tegner Activity Level (p = 0.797), and knee flexion angle (p = 0.135). There was also no significant difference in the incidence of complications among the three groups (p > 0.05).
There were not statistically differences in clinical functional results when comparing patients' endobutton location on femur. This indicates that it does not need to adjust the orientation of the exit hole of the femur whether it is forward or backward during the PCLR.
探讨股骨纽扣位置对后交叉韧带重建（PCLR）中膝关节功能的影响。
进行一项回顾性研究，分析2020年1月至2023年6月在我院接受单束后交叉韧带（PCL）重建的96例患者。根据膝关节外侧X线片上纽扣的位置将患者分为三组。第一组是纽扣位于股骨外侧皮质前方的位置，第二组是纽扣位于股骨外侧皮质后方的位置，第三组是纽扣位于股骨后方的位置。比较三组的膝关节Lysholm评分、国际膝关节文献委员会（IKDC）评估、Tegner活动量表、膝关节屈曲角度和术后并发症发生率，以评估三组之间是否存在统计学差异。
第一组有39例患者，第二组有46例患者，第三组有11例患者。第一组的平均Lysholm膝关节评分为91.77，第二组为92.17，第三组为90.36。第一组的平均IKDC评估为90.48，第二组为92.41，第三组为93.00。第一组的Tegner活动水平为5.69，第二组为5.72，第三组为5.45。第一组患者的平均屈曲度为125°，第二组为127°，第三组为122°。Lysholm膝关节评分（p = 0.434）、IKDC（p = 0.068）、Tegner活动水平（p = 0.797）和膝关节屈曲角度（p = 0.135）之间无统计学显著差异。三组之间的并发症发生率也无显著差异（p > 0.05）。
比较患者股骨上纽扣的位置时，临床功能结果无统计学差异。这表明在PCLR期间，无论股骨出口孔的方向是向前还是向后，都无需调整。
