| ObjectiveTo compare and analyze the clinical outcomes of arthroscopic single-row with two anchors and double-row suture-bridge technique repair for medium size rotator cuff tears through functional and magnetic resonance imaging(MRI)results.MethodsAccording to the inclusion and exclusion criteria,we analyze the cases of 51 patients who underwent arthroscopic repair of medium size rotator cuff tears in our hospital from January 2014 to December 2016.In group A,25 patients were repaired by single-row technique with two anchors,including 12 males and 13 females,with an average age of 54(29~67).In group B,26 patients were repaired by double-row suture-bridge technique,including 11 males and 15 females,with an average age of 53(32~72).All patients were given postoperative rehabilitation training.The visual analog pain scale(VAS),Constant-Murley score,Western Ontario Rotator Cuff(WORC)index,shoulder active range of motion(ROM)were recorded when preoperative and the last postoperative follow up were determined as the evolution criteria.At the end of the follow-up,MRI Sugaya classifications were used to compare the rotator cuff healing.ResultsAll 51 patients were followed up.The average follow-up of group A was 24(13~38)months,and the average follow-up of group B was 26(14~39)months.In group B underwent longer operation time(121.27±6.37 min versus 112.88±1.00min).In the two groups,the pain was relieved significantly,Constant-Murley score,and WORC index improved significantly.In group A,preoperative:the VAS score was(5.69±1.05),the Constant-Murley score was(33.80±6.47),the WORC index was(30.16 ±6.19),at the last postoperative follow-up:the VAS score was(0.53±0.57),the Constant-Murley score was(85.44±5.84),the WORC index was(83.99±5.82).In group B,preoperative:the VAS score was(5.72±1.16),the Constant-Murley score was(35.93±7.53),the WORC index was(33.89 ±7.27),at the last postoperative follow-up:the VAS score was(0.63±0.56),the Constant-Murley score was(86.38±5.29),the WORC index was(84.31±5.43).In the two groups,the shoulder active ROM improved greatly in forward flexion,abduction,90° abduction external rotation and 90° abduction internal rotation.There was a statistically significant difference in the preoperative and the last postoperative follow up(P<0.05),in the two groups about the functional outcomes,and there was no significant difference between the two groups about the functional outcomes(P>0.05).At the last follow-up,MRI results showed that the recurrent tear rate of group A was 8.0% and group B was 3.8%.About the Sugaya classification(I:II:III:IV:V),there was no significant difference between group A(10:7:6:1:1)and group B(13:8:4:1:0),P>0.05.The VAS score in the retear group was higher than that in the healing group(1.53±0.64 versus 0.53±0.51),and the two groups were compared with functional outcomes with no statistical difference(P>0.05).At the last postoperative follow-up,the functional outcomes of retear patients recovered well than preoperative.Conclusion1.Arthroscopic single-row with two anchors and double-row suture-bridge techniques repair of medium size rotator cuff tears results in good function and MRI outcomes in the early follow-up.Compared the functional and MRI outcomes with the single-row technique,double-row suture-bridge technique was no significant advantage,it remains to be seen what the long-term outcomes will be.2.The technique of arthroscopic single-row repair with two anchors for medium size rotator cuff tears indicating that the clinical outcomes were satisfied.Combining reasonable patients selection with effective postoperative treatment,this is an economic,security and effective method for repairing of medium size rotator cuff tears. |
