摘要
目的:探讨前交叉韧带(ACL)重建术后韧带移植物愈合情况及其影响因素。方法:选取2014年1月至12月期间的膝关节镜下ACL重建手术患者,记录患者的性别、年龄、体重、身高、体重指数(BMI)、关节松弛度评分(Beighton评分)和ACL断裂病程时长。术后6个月、1年和2年随访时进行核磁检查,测量韧带移植物近端、中部和远端的信号强度,并计算信噪比(SNQ),用以评估重建韧带的愈合情况。对数据进行统计分析,探讨韧带移植物的愈合情况及其影响因素。结果:共计87例ACL重建患者入选研究,结果显示韧带移植物近端和中部的SNQ值随时间延长逐渐减小,尤其近端的SNQ值2年与6个月、1年对比有显著性差异(P<0.05);韧带远端的SNQ值在术后6个月、1年和2年时间节点上无明显差异。性别、年龄、体重、身高、BMI、Beighton评分和ACL断裂时长等因素对韧带移植物的SNQ数值均无显著性影响(P>0.05)。结论:ACL重建术后韧带移植物的愈合情况随时间延长而逐步改善。
Objective To investigate the ligamentization process of autogenous hamstring gratis after anterior cruciate ligament （ACL）reconstruction and explore its potential influencing factors. Methods Patients undergoing the ACL reconstruction between January and December 2014 were recorded demographic data including their gender, age, weight, height, body mass index （BMI） , general joint relaxation（the Beighton score）,and their surgical duration. Six, 12,and 24 months after the operation, the signal intensity of the proximal,middle and distal part of the ACL grafts was measured using MRI, and the signal to noise quotient （SNQ）was calculated to assess the graft maturity. The data were analyzed statistically to explore the ligamentization process of gratis and its potential influencing factors. Results A total of 87 patients receiving ACL reconstruction were enrolled in this study. The results showed that the SNQ of the proximal and middle part of the ACL gratis decreased gradually with time, and significant differences were observed in the SNQ value of the proximal part between 24 months and that of 6 and 12 months（P〈0.05）. There was no significant difference in the SNQ value of the distal part at different time points. The SNQ values of gratis were not significantly affected by the gender, age, body weight, height, BMI, Beighton score or ACL duration （P〉0.05）. Conclusion The ligamentization of autogenous hamstring gratis after ACL reconstruction increases gradually with timent positive correlation with postoperative time.
