- Abstract: Objective To evaluate the efficacy of arthroscopic double row suture technique combined with knotless suture bridge technique in repairing medium and large rotator cuff tears.Methods 92 medium and large rotator cuff tears patients from January 2018 to October 2022 were randomly divided into two groups with 46 cases in each group.The observation group was administrated with arthroscopic double row suture combined with knotless suture bridge technique,while the control group was treated with arthroscopic single row suture combined with knotless suture bridge technique.The two groups were compared before and 3,6,and 12 months after surgery in terms of intermediate,medial and lateral T2 values of supraspinatus tendons,shoulder joint range of motion,and the scores on related scales[Constant-Murley scale,University of California,Los Angeles(UCLA)shoulder joint grading system,visual analogue scale(VAS)score],as well as the acromion-humeral head distance(A-H distance).And the joint stiffness and rotator cuff tears were collected from the two groups within 12 months after the operation.Results At 3,6 and 12 months after surgery,the intermediate,medial and lateral T2 values of supraspinatus tendons in both groups were gradually decreased,and were significantly lower than those before surgery,the differences were statistically significant(P<0.05),and the intermediate,medial and lateral T2 values of supraspinatus tendons at each time point in the observation group were significantly lower than those in the control group,the differences were statistically significant(P<0.05);At 3,6,and 12 months after surgery,the anterior flexion range of motion,lateral rotation range of motion,and A-H head distance of both groups were seeing a gradual increase,and the values were significantly higher than those before the treatment,the differences were statistically significant(P<0.05).The anterior flexion range of motion,lateral rotation range of motion and A-H head distance at each time point in the observation group were significantly greater than those in the control group,the differences were statistically significant(P<0.05);At 3,6,and 12 months after surgery,the Constant-Murley and UCLA scales of both groups were seeing a gradual increase,and the values were significantly higher than those before the treatment,the differences were statistically significant(P<0.05),and The Constant-Murley and UCLA scales of the observation group at each time point were significantly higher than those of the control group,the differences were statistically significant(P<0.05);At 3,6,and 12 months after surgery,the VAS score in both groups was lower than that before operation,the difference was statistically significant(P<0.05),the VAS score of the observation group at 3 months after surgery was significantly lower than that of the control group,the difference was statistically significant(P<0.05);12 months after surgery,the incidence of joint stiffness and rotator cuff retear in observation group were 2.17%and 0.00%,significantly lower than those in control group(17.39%and 13.04%),the differences were statistically significant(P<0.05).Conclusion The application of arthroscopic double row suture combined with knotless suture bridge technique can effectively promote postoperative rotator cuff tissue healing,improve the range of motion,function of the shoulder joint and A-H head distance,relieve shoulder pain and greatly reduce the occurrence of postoperative rotator cuff tear and joint stiffness compared with arthroscopic single row suture combined with knotless suture bridge technique.It is worthy clinical application.
