Clinical Outcomes Of Arthroscopic Repairing Full-thickness Rotator Cuff Tears By Suture-bridge And Double-row Techniques

ObjectiveBy comparing the clinical effect of using arthroscopic double-row(DR)and suture-bridge(SB)technique to treat full-thickness rotator cuff tears,research the arthroscopic treatment of full-thickness rotator cuff tears and provide clinical basis for orthopedic clinical doctors to choose surgical operation.MethodsA retrospective analysis of 40 patients who suffered full-thickness rotator cuff tears and treated by arthroscopic double-row or suture-bridge technique in China-Japan Union Hospital of Jilin University from January 2014 and January 2016.The collected patients were divided into double-row(DR)group and suture-bridge(SB)group randomly before operation.According to intraoperative measurement of rotator cuff tear length based on classification of Cofield dividing the patients into large tear(1-3 cm)group and massive tear(3-5 cm).Then doctor will use the corresponding surgical operation treatment according to the preoperative plan.All surgery operations are completed by the same high qualification doctor.Record the time of operation and the length of the rotator cuff tear.Measure shoulder joint ’ s range of abduction motion and evaluate shoulder joint according to visual analog scale(VAS)score in pre-operation and postoperative 1 week,1 month,3 months,6 months,12 months.According to Constant-Murley score,UCLA(University of California at Los Angeles Shoulder Scores)and Evaluate pre-and post-operative shoulder function of the two techniques after 1 year.To each group of data,adopting SPSS22.0 statistical software for data analysis,marking measuring data as x±s(mean±standard deviation).In the same degree of tear,using t test to compare the results of two groups of patients,P<0.05 was set as statistical significance,inspection level take ɑ = 0.05.ResultTwo groups of patients were received effective follow-up.The VAS of SB group was decreased obviously than that of DR groups and the ranges of abduction motion was increased obviously than that of DR groups in postoperative 1 week,1 month,3 months.DR group compared with SB group,preoperative UCLA,and Constant-Murley score had no obvious difference between two groups,the difference was not statistically significant(P>0.05),postoperative UCLA and Constant-Murley score had no obvious difference between two groups,the difference was not statistically significant(P>0.05).Operation time of SB group was obviously less than DR group.Two groups of operation time had obvious difference(P < 0.05).Compared with pre-operation,postoperative UCLA and Constant-Murley score had obviously increased in SB group and DR group,the difference was statistically significant(P<0.05).Conclusions1.The early clinical outcomes of suture bridge technique are superior to that of double row.Suture bridge technique can reduce postoperative soft tissue edema,increase the shoulder joint’s range of motion and relieve patients’ pain.2.Suture bridge technology’s operation time is shorter significantly than the double row technology’s.3.Midterm clinical outcomes of treating large and massive rotator cuff tears have no obvious difference between suture-bridge and double-row techniques.
