【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(P0.05);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(P0.05)。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。
[Abstract]:Objective: to investigate the healing of anterior cruciate ligament graft after ACL-reconstruction and its influencing factors.Methods: from January to December 2014, the patients undergoing ACL reconstruction under knee arthroscopy were selected to record their sex, age, weight, height, body mass index (BMI), joint relaxation score (Beighton score) and the duration of ACL rupture.After 6 months, 1 and 2 years of follow-up, nuclear magnetic resonance (NMR) was performed to measure the signal intensity of the proximal, middle and distal end of ligamentous graft, and to calculate the signal-to-noise ratio (SNQ) to evaluate the healing of the reconstructed ligament.To investigate the healing of ligament graft and its influencing factors.Results: a total of 87 patients with ACL reconstruction were enrolled in the study. The results showed that the SNQ values of the proximal and middle end of ligament graft gradually decreased with time.There was significant difference in SNQ value between 2 years and 6 months and 1 year in the proximal end of the ligaments (P 0.05), but there was no significant difference in the SNQ values of the distal ligaments at 6 months, 1 year and 2 years after operation.Sex, age, weight, height, BMI-Beighton score and ACL duration had no significant effect on the SNQ value of ligamentous graft.Conclusion the healing of ligamentum grafts after the reconstruction of ACL was improved gradually with the extension of time.
