Abstract

Background: To investigate the effect of the position of the femoral endobutton on knee function in the posterior cruciate ligament reconstruction (PCLR).

Methods: 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.

Results: 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).

Conclusion: 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.

股骨内扣位置对后交叉韧带重建中膝关节功能影响的回顾性研究。

背景：探讨股骨内扣位置对后交叉韧带重建术（PCLR）膝关节功能的影响。方法：回顾性分析2020年1月至2023年6月在我院行后交叉韧带单束重建术的96例患者。根据内扣在膝关节侧位片上的位置将患者分为三组。第一组是内扣在股骨外侧皮质前面的位置，第二组是内扣在股骨外侧皮质后面的位置，第三组是内扣在股骨后面的位置。比较三组患者膝关节Lysholm评分、国际膝关节文献委员会（International Knee Documentation Committee， IKDC）评分、Tegner活动量表、膝关节屈曲角度及术后并发症发生率，评估三组间是否有统计学差异。结果：1组39例，2组46例，3组11例。组1平均Lysholm膝关节评分91.77，组2平均Lysholm膝关节评分92.17，组3平均Lysholm膝关节评分90.36。组1平均IKDC评分90.48，组2平均IKDC评分92.41，组3平均IKDC评分93.00。1组Tegner活性水平为5.69,2组为5.72,3组为5.45。第1组患者平均屈曲度为125°，第2组为127°，第3组为122°。Lysholm膝关节评分（p = 0.434）、IKDC （p = 0.068）、Tegner活动水平（p = 0.797）、膝关节屈曲角度（p = 0.135）之间差异无统计学意义。三组患者并发症发生率比较，差异无统计学意义（p < 0.05）。结论：两组患者股骨内扣位置比较，临床功能结果无统计学差异。这表明在PCLR过程中，无论是向前还是向后，都不需要调整股骨出口孔的方向。

期刊介绍： Journal of Orthopaedic Surgery and Research is an open access journal that encompasses all aspects of clinical and basic research studies related to musculoskeletal issues. Orthopaedic research is conducted at clinical and basic science levels. With the advancement of new technologies and the increasing expectation and demand from doctors and patients, we are witnessing an enormous growth in clinical orthopaedic research, particularly in the fields of traumatology, spinal surgery, joint replacement, sports medicine, musculoskeletal tumour management, hand microsurgery, foot and ankle surgery, paediatric orthopaedic, and orthopaedic rehabilitation. The involvement of basic science ranges from molecular, cellular, structural and functional perspectives to tissue engineering, gait analysis, automation and robotic surgery. Implant and biomaterial designs are new disciplines that complement clinical applications. JOSR encourages the publication of multidisciplinary research with collaboration amongst clinicians and scientists from different disciplines, which will be the trend in the coming decades.
