METHODS: The semitendinosus and gracilis tendons are braided into 5 strands and the ACL femoral tunnel and tibial tunnel are created. The graft is passed through the tunnel with the use of a traction suture and the tibial end is fixed with absorbable interference screws at 30° of knee flexion. The ACL graft traction suture is used as an anterolateral reconstruction structure to pass through the proximal exit of the ACL femoral tunnel and then through the depth of the iliotibial bundle to the anterior to Gerdy\'s tubercle, a bony tunnel is created from the anterior to Gerdy\'s tubercle to the goose foot, and the traction suture is passed through this bony tunnel to form a Loop structure at 20° of knee flexion. Between March 2021 and May 2022 IKDC score, Lysholm score, and Tegner score were performed preoperatively and 6-12 months postoperatively in 24 consecutive patients who met the indications for this procedure and underwent surgery. The patient\'s maximum flexion angle, the circumference of the thigh, and the stress X-ray between the operated and healthy knee were measured.
RESULTS: Patients showed significant improvement in IKDC score, Lysholm score and Tegner score at a mean follow-up of 7 months postoperatively compared to preoperatively. No significant increase in anterior tibial displacement was found between the patient\'s operated side and the healthy side.
CONCLUSIONS: The Loop technique ACLR combined with ALSA can be used in patients with an ACL tear combined with a high degree of positive pivot shift. The patient\'s subjective perception was significantly improved from the preoperative period and knee stability was restored.
METHODS: IV, therapeutic study.
方法:将半腱肌腱和股薄肌腱编织成5股,并创建ACL股骨隧道和胫骨隧道。使用牵引缝合线将移植物穿过隧道,并在膝关节屈曲30°时用可吸收的干涉螺钉固定胫骨端。ACL移植物牵引缝合线用作前外侧重建结构,穿过ACL股骨隧道的近端出口,然后穿过髂胫骨束的深度到达Gerdy结节的前部,从格尔迪的结节到鹅脚形成了一条骨隧道,并且牵引缝合线穿过该骨隧道以在膝关节屈曲20°处形成环结构。2021年3月至2022年5月IKDC评分,Lysholm得分,对24例符合该手术指征并接受手术的患者进行了术前和术后6-12个月的Tegner评分。患者的最大屈曲角度,大腿的周长,并测量了手术和健康膝盖之间的应力X射线。
结果:患者IKDC评分显著改善,术后平均随访7个月的Lysholm评分和Tegner评分与术前相比。在患者的手术侧和健康侧之间没有发现胫骨前位移的显着增加。
结论:Loop技术ACLR联合ALSA可用于ACL撕裂并伴有高度正枢轴移位的患者。患者的主观感知从术前明显改善,膝关节稳定性恢复。
方法:IV,治疗性研究。
