title: Long-term functional outcome of repair of large and massive chronic tears of the rotator cuff.
abstract: BACKGROUND
  There have been conflicting reports regarding the effect of the size of a tear of the rotator cuff on the ultimate functional outcome after repair of the rotator cuff. While some authors have reported that the size of the tear does not adversely affect the overall result of repair, others have reported that the outcome is less predictable after repair of a large tear than after repair of a small tear. The purpose of the present study was to examine the long-term functional outcome and the recovery of strength in thirty consecutive patients who had had repair of a large or massive tear of the rotator cuff.
  
  
  METHODS
  Thirty consecutive patients who had operative repair of a large or massive chronic tear of the rotator cuff had a comprehensive isokinetic assessment of the strength of the shoulder preoperatively, twelve months postoperatively, and a mean of sixty-five months (range, forty-six to ninety-three months) postoperatively. The functional outcome was assessed with the University of California at Los Angeles shoulder score.
  
  
  RESULTS
  All patients reported that they were satisfied with the result and had increased strength compared with preoperatively. There was a significant decrease in pain (p < 0.01) and significant improvements in function (p < 0.01) and the range of motion (p < 0.01). The mean University of California at Los Angeles shoulder score increased significantly from 12.3 points preoperatively to 31.0 points at the most recent follow-up examination (p < 0.01). The mean peak torque in flexion, abduction, and external rotation increased significantly to 80 percent (p < 0.01), 73 percent (p < 0.01), and 91 percent (p < 0.01), respectively, of that of the uninvolved shoulder by the time of the most recent follow-up examination.
  
  
  CONCLUSIONS
  Repair of a large or massive tear of the rotator cuff can have a satisfactory long-term outcome. The results of the present study suggest that more than one year is needed for complete restoration of strength. The strength of the affected shoulders still did not equal that of the unaffected, contralateral shoulders by the time of the long-term follow-up.
