Application of Ultra-short Echo Time Magnetic Resonance T2* Technique in the Evaluation of Ligamentization of Tendon Grafts after Anterior Cruciate Ligament Reconstruction
Objective To evaluate the application of ultra-short echo time-T2*technique of magnetic resonance imaging(MRI)in the evaluation of ligamentization of tendon transplantation(ACLR)after anterior cruciate ligament reconstruction.Methods A total of 118 patients who planned to undergo anterior cruciate ligament reconstruction in our hospital from August 2019 to January 2023 were selected as study subjects(study group),and 32 healthy volunteers who underwent physical examination in our hospital during the same period were selected as control group.MRI UTE-T2 technology and clinical scores were performed on knee joint.To explore the efficacy of MRI-UTE-T2 technique in the evaluation of ligamentization of tendon grafts after anterior cruciate ligament reconstruction.Results There were no significant differences in the T2 values of FM,TM,TL,P and TrF cartilage areas between the two groups(P＞0.05).The T2 values of FM,FL and FL weight-bearing areas in the study group at 1 month,6 months and 12 months after surgery were significantly higher than those in the control group,with statistical significance(P＜0.05).Conclusion The knee cartilage function of ACL patients is significantly improved after ACLR,and the application of MRI-UTE-T2 technique is of certain value in the evaluation of ACL graft ligamentization after ACLR.
