目的:研究磁共振T2-mapping在膝关节前交叉韧带重建术后软骨变性和移植物成熟度评估方面的作用.方法:选取2019年12月~2022年9月于本院骨科收治的膝关节前交叉韧带损伤患者51例为观察组对象和正常成年志愿者51例为对照组.比较两组对象膝关节软骨T2值、关节内段移植物ADC值及T2值的差异,分析观察组患者术后早期、中期的移植物ADC值及T2值与临床功能评分(IKDC、Lysholm评分)间的相关性.结果:术后12个月,观察组患者LF负重区、MF负重区及MT区的软骨T2值均显著大于对照组.观察组患者术后6个月的关节内近段、中段、远段及整个关节内段的移植物T2值均显著高于对照组,术后6个月的关节内近段的移植物T2值显著大于关节内远段及中段.结论:磁共振T2-mapping在膝关节前交叉韧带重建术后软骨变性和移植物成熟度评估方面具有一定价值.
Magnetic Resonance T2-Mapping for the Evaluation of Cartilage Degeneration and Graft Maturity After ACL Reconstruction
Objective:To investigate the role of magnetic resonance T2-mapping in the assessment of cartilage degeneration and graft maturity after ACL reconstruction.Methods:A total of 51 patients with ACL injury admitted to the Department of Orthopedics of our hospital from December 2019 to September 2022 were selected as the observation group,and 51 cases of normal adult as the control group.The differences between knee cartilage T2 values,intraarticular segment graft T2 values were compared between the two groups.The correlation between graft ADC and T2 values and clinical function scores(IKDC and Lysholm)in the early and middle postoperative period of the observation group was analyzed.Results:At 12 months after surgery,the cartilage T2 values in the LF weight-bearing area,MF-weight-bearing area and MT area in the observation group were significantly higher than those in the normal control group.The T2 values of the proximal,middle,distal and entire intraarticular segment of the observation group were significantly higher than those of the control group 6 months after operation,and the T2 values of the proximal intra-articular graft in the 6 months after surgery were significantly higher than those in the distal and mid-articular segments.Conclusion:Magnetic resonance T2-mapping has some value in the assessment of cartilage degeneration and graft maturity after anterior cruciate ligament reconstruction of the knee.
