Clinical Research Of Full-thickness Rotator Cuff Tears With The Anterior Disruption Of The Rotator Cable

Objective:Comparison of clinical results in the arthroscopic repair of full-thickness rotator cuff tears with and without the anterior disruption of the rotator cable.Method:Between September 2015 and April 2017,64 patients(34 males and 30 females)with the full-thickness rotator cuff tears,with an average of 12.5 months(12-15 months)follow-up,were recruited in the study.The anterior attachment of the rotator cable was disrupted in 34 shoulders and intact in 30 shoulders.There was no significant difference in age,sex,side and preoperative course between the two groups(P>0.05).The tear size,morphology and muscle fat infiltration of the two groups were recorded and compared before operation.Postoperative functional scores,range of motion,and recurrence rate of tear in 2 groups were observed and compared.Results:There were statistically significant differences in the preoperative tear size and pattern and muscle fatty degeneration between the 2 groups(P<0.05).All incisions healed at stage?without postoperative complication.At final follow-up,the UCLA score,ASES score,VAS score,Constant score,and the range of motion were measured at 12 months have significantly improved when compared with the preoperative values in 2 groups(P<0.05).However,there was no significant difference between the two groups before the operation(P>0.05).In assessing the repair integrity on postoperative MRI,nine cases(26.5%)of rotator cuff tear recurred in injured group while two cases(6.7%)in intact group,showing statistically significant difference(P<0.05).Conclusion:Irrespective of involvement in the anterior attachment of the rotator cable,the follow-up demonstrated excellent pain relief and improvement in the ability to perform activities of daily living after arthroscopic rotator cuff repair.However,there were significant differences in preoperative tear size,tear pattern and fatty degeneration between tears with and without the anterior disruption of the rotator cable.Additionally,the retear rate was significantly higher in patients with a tear involving the anterior attachment of the rotator cable.
