摘　　要：目的:探讨测量MRI腘绳肌腱横截面积在行前交叉韧带重建术前与前交叉韧带重建中移植物的相关性。方法:收集2021年11月至2022年3月在骨关节科拟行前交叉韧带重建术的50例患者的MRI资料,男32例,女18例,年龄19~48(31.1±8.7)岁。术前对半腱肌和股薄肌腱进行MRI测量并记录,然后在关节镜下行前交叉韧带重建术,术中取股薄肌腱与半腱肌腱来制备最终所需移植的肌腱,并且在术中测量已制备好的最终移植物的直径。最后使用统计学软件分析得到数据。结果:MRI测量半腱肌肌腱横截面积、股薄肌肌腱横截面积、半腱肌肌腱与股薄肌肌腱横截面积之和与前交叉韧带术中所需移植物的直径大小呈显著正相关,r值分别为0.858、0.728、0.842(P<0.001),半腱肌肌腱与股薄肌肌腱横截面积之和的曲线下面积(area uder curve,AUC)、灵敏度、和特异性分别为0.925、90.48%、85.71%。结论:在进行前交叉韧带重建术的患者中,术前MRI测量与术中腘绳肌移植直径大小有具有较强的统计学相关性,半腱肌肌腱与股薄肌肌腱横截面积之和对于前交叉韧带重建术中移植物的直径大小有较高的预测价值,可以预测术中移植物的大小。Objective To study the corretation between the cross-sectional area of hamstring tenden measured by MRI and gragt in anterior cruciate ligament rexonstruction.Methods MRI data of 50 patients who planned to undergo anterior cruciate ligament reconstruction from November 2021 to March 2022 were collected,including 32 males and 18 females,aged from 19 to 48 years old with an average of(31.1±8.7)years.Before the operation,the semitendinosus and gracilis tendons were measured and recorded by MRI,and then the anterior cruciate ligament was reconstructed under arthroscope.During the operation,gracilis and semitendinosus tendons were taken to prepare the final tendon to be transplanted,and the diameter of the prepared final graft was measured during the operation.Finally,the data were analyzed by statistical software.Results The cross sectional areas of semitendinosus tendon,gracilis tendon,semitendinosus tendon and gracilis tendon measured by MRI were significantly and positively correlated with the diameter of grafts required in anterior cruciate ligament surgery,the r values were 0.858,0.728,0.842(P<0.001),respectively.The area under curre(AUC),sensitivity,and specificity of the sum of the cross sectional areas of semitendinosus tendon and gracilis tendon were 0.925,90.48%,and 85.71%,respectively.Conclusion In patients undergoing anterior cruciate ligament reconstruction,preoperative MRI measurement has a strong statistical correlation with the diameter of hamstring muscle transplantation during operation.The sum of the cross sectional areas of semitendinosus tendon and gracilis tendon has a high predictive value for the diameter of grafts during anterior cruciate ligament reconstruction,and can predict the size of grafts during operation.
