MRI Imaging was Used to Evaluate the Effect of Rotator Cuff Repair on Rotator Cuff Injury
Objective:To explore the value of magnetic resonance imaging(MRI)in evaluating rotator cuffrepair for rotator cuff injury.Methods:Seventy patients who received arthroscopic rotator cuffrepair in our hospital from January 2020 to August 2022 were selected as the study objects.Routine MRI detection and T2 mapping sequence examination were performed on them before surgery and 6 months after surgery,respectively.According to the results,70 patients were divided into good prognosis group(n=49)and poor prognosis group(n=21).Compared the proportion of low-grade MRI,the differences in intermediate,medial and lateral T2 values of supraspinatus tendon before surgery and 6 months after surgery,and the differences in shoulder joint rating scale(CMS)and University of California Shoulder Joint score(UCLA)scores of enrolled patients before surgery and 6 months after surgery,the correlation analysis between CMS and UCLA scores and T2 values of enrolled patients was evaluated.The value of intermediate,medial and lateral T2 values of supraspinatus tendon in the prognosis of patients undergoing rotator cuff repair was calculated by receiver characteristic curve(ROC).Results:The T2 values of the medial,medial and lateral parts of supraspinatus tendon in the good prognosis group were lower than those in the poor prognosis group at the same time point before and 6 months after surgery.6 months after surgery,the intermediate,medial and lateral T2 values of supraspinatus tendons in 2 groups were decreased before and 6 months after surgery,the difference was statistically significant(P<0.05).Before and after surgery,the CMS and UCLA scores of patients in the good prognosis group were significantly higher than those in the poor prognosis group,and 6 months after surgery,the CMS and UCLA scores of patients in the 2 groups were increased,the difference was statistically significant(P<0.05).Pearson analysis was carried out on the correlation between T2 values of enrolled subjects and their CMS and UCLA scores before and 6 months after surgery,which showed that T2 values of enrolled subjects were significantly negatively correlated with their CMA and UCLA scores before and 6 months after surgery,with statistical significance(P<0.001).The evaluation value of the intermediate,medial and lateral T2 values of supraspinatus tendon in the prognosis of patients undergoing rotator cuffrepair was calculated.The results showed that the AUC of the intermediate,medial and lateral T2 values of supraspinatus tendon before surgery was 0.7762,0.9275 and 0.9043,respectively,with statistical significance(P<0.05).At 6 months after surgery,the AUC of intermediate,medial and lateral T2 values of supraspinatus tendon for adverse prognosis assessment after repair was 0.9884,0.7261 and 0.9012,respectively,with statistical significance(P<0.05).Conclusion:MRI imaging has good evaluation value for patients with rotator cuffrepair,can better quantitatively evaluate the postoperative recovery of patients,and also has a certain evaluation value for the prognosis of patients,which has the prospect of popularization and application.
