目的：探究界面螺钉联合普通螺钉固定前交叉韧带（anterior cruciate ligament，ACL）重建移植物胫骨端的临床疗效。方法：将2024年4月至2025年4月收治的72例ACL断裂行关节镜下单束重建术患者，按随机数字表法分为单纯界面螺钉固定组（对照组）和界面螺钉联合普通螺钉固定组（观察组），每组36例。于术前及术后3、6、12个月采用Lysholm评分、IKDC评分及Tegner活动评分评价膝关节功能；术后12月基于CT三维重建评估胫骨骨道宽度变化；记录手术时间、出血量、引流量及住院天数。采用SPSS 25.0软件分析数据，P＜0.05为差异具有统计学意义。结果：两组基线特征无显著差异（P＞0.05）。两组术后Lysholm评分均较术前提高，术后3月、6月及12月的观察组评分均明显高于对照组（P＜0.05）。IKDC评分，观察组于术后6、12月显著优于对照组（P＜0.05）。Tegner评分，观察组于术后3月及12月显著优于对照组（P＜0.05）。两组手术时间、出血量、引流量及住院天数均无显著差异（P＞0.05）。术后12月观察组的胫骨骨道宽度增加量小于对照组（P＜0.05）。结论：ACL重建术中，采用界面螺钉联合普通螺钉固定胫骨端移植物，可在不增加手术创伤与风险的情况下，更有效地促进膝关节功能恢复、减少胫骨骨道扩大，值得临床推广应用。
