This study compared the clinical outcomes of patients treated with described “modified all-inside” anterior cruciate ligament reconstruction (ACLR) technique with those of patients treated with suspensory femoral fixation and a bioabsorbable tibial interference screw with the ACLR technique. From 2017 to 2019, 98 patients who underwent ACLR surgery by two surgeons using either of the techniques were included in this study. Patients in group 1 were treated with the “modified all-inside” ACLR technique. In this technique, only the semitendinosus tendon was harvested as a four-strand graft and fixed to the tibia and femur with suspensory buttons. Patients in group 2 were treated with suspensory femoral fixation and a bioabsorbable tibial interference screw ACL reconstruction technique. Patients' functional outcomes were evaluated by the Lysholm score, Tegner activity scale, and International Knee Documentation Committee (IKDC) subjective score. Postoperative knee stability of the patients was evaluated using the Lachman test and the pivot-shift test. The mean ages of the patients were 31.1 (16–55) and 28.7 (18–48) years in groups 1 and 2, respectively. The average follow-up durations were 26 (20–30) and 25.9 (22–30) months for both groups. There was no significant difference between the preoperative and postoperative Lysholm's score, Tegner's activity score, and IKDC subjective score in groups 1 and 2. There were no major complications or reruptures in either group. ACLR incorporating the “modified all-inside” ACLR technique obtained significant clinical outcomes compared to ACLR with a suspensory femoral fixation and a bioabsorbable tibial interference screw.

本研究比较了采用所述“改良全内”前交叉韧带重建 (ACLR) 技术治疗的患者与采用股骨悬吊固定和生物可吸收胫骨干扰螺钉与 ACLR 技术治疗的患者的临床结果。本研究纳入了 2017 年至 2019 年期间由两名外科医生使用任一技术接受 ACLR 手术的 98 名患者。第 1 组患者接受“改良 all-inside”ACLR 技术治疗。在这项技术中，仅将半腱肌腱作为四股移植物收获，并用悬纽扣固定到胫骨和股骨上。第 2 组患者接受股骨悬吊固定和生物可吸收胫骨干扰螺钉 ACL 重建技术治疗。通过 Lysholm 评分、Tegner 活动量表和国际膝关节文献委员会 (IKDC) 主观评分来评估患者的功能结果。使用拉赫曼试验和枢轴移位试验评估患者术后膝关节稳定性。第 1 组和第 2 组患者的平均年龄分别为 31.1（16-55）岁和 28.7（18-48）岁。两组的平均随访时间分别为 26 (20-30) 和 25.9 (22-30) 个月。第1组和第2组术前、术后Lysholm评分、Tegner活动评分和IKDC主观评分无显着差异。两组均未出现重大并发症或再断裂。与采用悬吊股骨固定和生物可吸收胫骨干扰螺钉的 ACLR 相比，采用“改良全内”ACLR 技术的 ACLR 获得了显着的临床效果。
