目的:探讨新型自体半腱肌带状移植物重建术治疗膝关节前交叉韧带（ACL）断裂的早期疗效。方法:采用回顾性队列研究分析2019年6月至2021年1月郑州市骨科医院收治的65例膝关节ACL断裂患者的临床资料，其中男52例，女13例；年龄16~50岁［（30.5±8.4）岁］。根据重建方式和移植物选择，将患者分为带状重建组（31例）和圆束重建组（34例）。手术重建方法均为解剖重建，其中带状重建组采用新型自体半腱肌带状移植物解剖重建ACL，圆束重建组采用传统圆束状移植物解剖重建ACL。比较两组手术时间、术后即时ACL移植物与原始ACL形态差异、术前及术后3个月Lysholm评分、术后即时及术后3个月Lachman试验和轴移试验、术中及术后并发症发生情况。结果:患者均获随访3~15个月［（6.0±3.1）个月］。带状重建组手术时间为（61.6±6.7）min，圆束重建组为（48.0±6.3）min（n P0.05）。术后3个月带状重建组出现1例胫骨切口感染；圆束重建组未出现切口感染，创面均Ⅰ期愈合；两组均无韧带失效及功能受限发生（n P>0.05）。n 结论:新型自体半腱肌带状移植物重建ACL的临床效果与传统圆束移植物相当。然而，关节镜下发现带状移植物实质部为带状，更好地模拟了原始ACL的生理形态，在屈膝时模仿ACL发生自然扭曲，可能会更好模拟原始ACL的生理功能。“,”Objective:To investigate the early curative effect of the new autologous semitendinosus ribbon-like graft in reconstruction of anterior cruciate ligament (ACL) tear.Methods:A retrospective cohort study was conducted to analyze the clinical data of 65 patients with knee ACL tear admitted to Zhengzhou Orthopedics Hospital from June 2019 to January 2021, including 52 males and 13 females, aged 16-50 years [(30.5±8.4)years]. According to the reconstruction method and graft selection, the patients were divided into ribbon-like reconstruction group (n n=31) and circular bundle reconstruction group (n n=34). All patients underwent anatomical ACL reconstruction using the new autologous semitendinosus ribbon-like graft in ribbon-like reconstruction group and the traditional circular bundle graft in circular bundle reconstruction group. The operation time, morphological difference in ACL graft immediately after surgery with original ACL, Lysholm score before and at 3 months after surgery, Lachman test and axial shift test immediately and at 3 months after surgery, and intraoperative and postoperative complications were compared between the two groups.n Results:All patients were followed up for 3-15 months [(6.0±3.1)months]. The operation time was (61.6±6.7)minutes in ribbon-like reconstruction group and was (48.0±6.3)minutes in circular bundle reconstruction group (n P0.05). One patient experienced tibial incision infection in ribbon-like reconstruction group at 3 months after surgery. All wounds were healed at stage I with no incision infection in circular bundle reconstruction group. No patients had ligament failure or function limitation. There was no significant difference in postoperative complications between the two groups (n P>0.05).n Conclusions:The clinical effect of new autogenous semitendinosus ribbon-like graft in ACL reconstruction is comparable to that of traditional circular bundle graft. However, arthroscopic observation reveals that the parenchymal part of the ribbon-like graft is ribbon-shaped, which better simulates the physiological morphology of the original ACL. The natural distortion of the simulated ACL during knee bend may better simulate the physiological function of the original ACL.
