摘要
目的:探索采用腘绳肌腱前交叉韧带重建术(ACLR)后1年内腱骨愈合的磁共振成像(MRI)信号变化规律,并探讨腱骨愈合情况与临床主观功能评分的关系。方法:回顾性分析30例男性患者于2019年1月至2020年12月在深圳市第二人民医院采用腘绳肌腱行ACLR术后的3、6、12个月不同时间节点MRI上腱骨结合部的信号变化;其中腱骨愈合程度以胫骨段及股骨段骨道内移植物的信噪比(SNQ)表示。采用重复测量方差分析比较不同时间节点的骨道内移植物SNQ值的差异,采用t检验比较同一时间节点胫骨、股骨骨道内移植物的SNQ值的差异。结果:在术后3、6、12个月,股骨段及胫骨段移植物的SNQ值在3个月开始逐渐升高,6个月达峰,随后逐渐下降;股骨段内移植物的SNQ值在3、6、12个月之间的差异具有统计学意义(F=6.88,P<0.05);胫骨段移植物的SNQ值在3、6、12个月不同时间节点组间差异无统计学意义(F=2.87,P>0.05)。在术后1年内,同一时间节点,股骨段移植物的SNQ值显著高于胫骨段,差异具有统计学意义(P<0.05)。结论:前交叉韧带腱骨结合部信号在6月达峰,随后逐渐下降,股骨段愈合差于胫骨段。
Objective To explore the changes of magnetic resonance imaging(MRI)signals of tendon healing within 1 year after anterior cruciate ligament reconstruction(ACLR),and to explore the relationship between tendon healing and clinical subjective function score.Methods The signal changes of tendine-bone junction on MRI at different time nodes at 3,6,and 12 months after ACLR with hamstring tendon were performed in 30 male patients in Shenzhen Second People's Hospital from January 2019 to December 2020 were retrospectively analyzed.The healing degree of tendon bone was indicated by the signal-to-noise ratio(SNQ)of the intraosseous grafts of tibia and femur.Repeated measurement ANOVA was used to compare the differences in SNQ values of intraosseous grafts at different time nodes,and T-test was used to compare the differences in SNQ values of intraosseous grafts of tibia and femur at the same time nodes.Results At 3,6,and 12 months after operation,SNQ values of femoral and tibial grafts gradually increased at 3 months,reached a peak at 6 months,and then gradually decreased.The SNQ values of the grafts in the femoral segment were significantly different at 3,6,and 12 months(F=6.88,P<0.05).There was no significant difference in SNQ value of tibial segment grafts among different time nodes at 3,6,and 12 months(F=2.87,P>0.05).Within 1 year after surgery,the SNQ value of femoral segment graft was significantly higher than that of tibia segment at the same time point,the difference was statistically significant(P<0.05).Conclusion The signal of anterior cruciate ligament tendine-bone junction reached a peak in June,and then gradually decreased,and the healing of femur segment was worse than that of tibia segment.
