Clinical Effect Of Arthroscopic Suture-bridge Technology And Traditional Double-row Suture Technique In The Treatment Of Massive Rotator Cuff Tears

Objective: To compare the clinical effect of arthroscopic suture-bridge technology and traditional double-row suture technique in the treatment of massive rotator cuff tears,and discuss the arthroscopic treatment method of massive rotator cuff tears,which was used as a reference for clinical doctors to choose surgical methods.Method: A retrospective study was conducted on 43 patients who underwent arthroscopic suture-bridge(SB)technique or double-row(DR)suture technique in the Department of Orthopedic Joint Minimally Invasive and Sports Medicine of Shanxi Provincial People’s Hospital between January 2019 and March 2022 for massive rotator cuff tears(MRCT).Each patient was diagnosed as MRCT by X-ray and magnetic resonance imaging(MRI)before surgery,and intraoperative arthroscopic exploration confirmed the diagnosis of MRCT,and all surgeries were performed by the same senior and experienced physician.collecting the duration of surgery and the number of anchors in all patients,and recording visual analogue scores(VAS)for pain at 1,3,6 and 12 months pre-and post-operative,shoulder abduction elevation range of motion at 3,6 and 12 months pre-and post-operative,and University of California at Los Angeles shoulder scores pre-and post-operative at 6 and 12 months,UCLA),Constant-Murley Shoulder Function Score,and American Shoulder and Elbow Surgeons Score(ASES).The collected patient data were divided into SB group and DR group according to surgical modality and SPSS26.0 statistical software was used for data analysis,the measurement data were expressed by mean ± standard deviation(x ± s),repeated test ANOVA was used for comparison of preoperative and postoperative time node scores in the group,independent sample t-test was used for comparison between the two groups,P<0.05 indicated that the difference was statistically significant,and the test level was α=0.05.Result: Both groups completed postoperative follow-up,and the postoperative shoulder abduction range of motion and VAS score in the SB group and DR group were significantly improved compared with before surgery(P<0.05).The recovery of abduction range of motion in the first 6 months after surgery was better in the SB group than in the DR group(P<0.05),but there was no significant difference between the two at last follow-up(P>0.05);the VAS score in the SB group was better than that in the DR group(P<0.05)at the first and third months of follow-up,but no significant difference was found between the two groups(P>0.05)in the subsequent 6th and 12 th months follow-up;the shoulder function scores of the two groups were significantly better than those before surgery(P<0.05),and the postoperative UCLA in the SB group The scores of Constant,and ASES were better than those of the DR group at 6 months follow-up(P<0.05),but there was no significant difference in the results at 12 months of follow-up between the two groups(P>0.05);there was no significant difference in the number of anchor nails used between the two groups(P>0.05),but the operation time was shorter in the SB group than in the DR group(P<0.05).Conclusion: Arthroscopic suture-bridge is superior to conventional double-row suture techniques for treating large rotator cuff tears in the early stages,but does not show significant differences in medium-term efficacy.Compared with the traditional doublerow suture technique,suture-bridge technology can shorten the operation time,reduce postoperative tissue edema,significantly reduce shoulder pain,improve joint mobility,and perform shoulder function exercise earlier in the early postoperative period.
