Objective To explore the changes and clinical significance of magnetic resonance (MR) signal features after meniscus suture.Methods A total of 60 patients suffering meniscus tear to receive arthroscopic treatment in our hospital were divided into an observation group (healing group) and a control group (non-healing group) according to the results of the second arthroscopic detection.All the patients received MR examination before the second arthroscopic detection 18 months before and after the operation.The changes of signal features of the meniscus and the difference in signal noise ratio (SNR) between the two groups were observed.Results Compared with the situation before the treatment,the postoperative abnormal signal length and width of menisci between the two groups 18 months later were significantly reduced (P ＜ 0.05),and the improvement of the postoperative abnormal signal length and width in the observation group was significantly better than that in the control group (P ＜ 0.05).The depth ratio of abnormal signal in PDWI and T2WI of menisci in the observation group (postoperative value/ preoperative value) was significantly lower than that in the control group,and the measured value in PDWI was significantly higher than that in T2WI (P ＜ 0.05).After the treatment,SNRs in PDWI and T2WI sequences in the two groups decreased significantly and the improvement in the observation group was significantly better than that in the control group (P ＜ 0.05).Conclusion After meniscus suture,the abnormal signal changes are regular.Evaluation on abnormal signal changes is helpful for evaluating the prognosis of the patients.
