目的:比较经胫骨入路与经辅助内侧入路制备股骨隧道类等长重建前交叉韧带（ACL）的位点和疗效。方法:回顾性分析2018年1月至2019年12月期间解放军第九〇四医院骨科收治的47例ACL断裂患者资料。根据不同手术入路分为两组：A组21例，男15例，女6例；年龄为（29.5 ± 4.8）岁；采用经胫骨入路可调袢钢板固定重建ACL。B组26例，男18例，女8例；年龄为（31.2 ± 9.6）岁；采用经辅助内侧入路可调袢钢板固定重建ACL。比较两组患者的股骨隧道位置、末次随访时膝关节Lysholm评分及国际膝关节文献委员会评分（IKDC）、膝关节前后及旋转稳定性等。结果:两组患者术前一般资料的比较差异均无统计学意义（n P>0.05），具有可比性。47例患者术后获18~27个月（平均22.3个月）随访。四格表法定位股骨隧道内口中心位点：A组和B组患者的X轴位点分别为25.6% ± 2.5%、26.7% ± 1.8%，差异无统计学意义（n P>0.05），Y轴位点分别为19.8% ± 2.0%、30.6% ± 1.5%，差异有统计学意义（n P0.05）。末次随访时两组患者之间前抽屉试验、Lachman试验及轴移试验结果比较差异均无统计学意义（n P>0.05）。n 结论:经胫骨入路和经辅助内侧入路制备股骨隧道类等长重建ACL，前者位点较后者更接近髁顶位置，二者术后近期均能获得满意疗效。“,”Objective:To compare the location and efficacy of femoral tunnel near-isometric reconstruction of anterior cruciate ligament (ACL) between the transtibial and assisted medial approaches.Methods:The clinical data of 47 patients were retrospectively analyzed who had been admitted by Department of Orthopaedics, The 904 Hospital of PLA for ACL rupture from January 2018 to December 2019. They were divided into 2 groups according to different surgical approaches. In groups A of 21 cases, there were 15 males and 6 females with an age of (29.5 ± 4.8) years and their ACL was reconstructed through the transtibial approach with adjustable Endobutton plate; in group B of 26 cases, there were 18 males and 8 females with an age of (31.2 ± 9.6) years and their ACL was reconstructed through the assisted medial approach with adjustable Endobutton plate. The 2 groups were compared in terms of location of femoral tunnel, Lysholm score and International Knee Documentation Committee (IKDC) score at the last follow-up, and anterior-posterior and rotational stability of the knee joint.Results:There was no significant difference in the preoperative general data between the 2 groups, showing comparability (n P>0.05). The 47 patients were followed up for 18 to 27 months (average, 22.3 months). As for the center of the inner opening of the femoral tunnel located by the four grid table method, the X-axis loci was 25.6% ± 2.5% and 26.7% ± 1.8% respectively in groups A and B, showing no statistically significant difference (n P>0.05) while the Y-axis loci 19.8% ± 2.0% and 30.6% ± 1.5% respectively in groups A and B, showing a statistically significant difference (n P0.05). There was no significant difference either in the results of front drawer test, Lachman test or axial displacement test between the 2 groups (n P>0.05).n Conclusion:In femoral tunnel near-isometric reconstruction of ACL, the transtibial approach can result in a tunnel location which is closer to the top of the condyle than the assisted medial approach, but both approaches can lead to satisfactory curative efficacy in the short postoperative period.
