title: [Effectiveness analysis of arthroscopically assisted treatment of rotator cuff injury].
abstract: OBJECTIVE
  To explore the method and effectiveness of arthroscopically assisted treatment of rotator cuff injury.
  
  
  METHODS
  Between November 2009 and March 2011, 27 patients with rotator cuff injury were treated. There were 17 males and 10 females with a mean age of 43.6 years (range, 29-66 years). The disease duration was 1 to 36 months (mean, 27 months). The location was the left shoulder in 11 cases and the right shoulder in 16 cases. Of them, 12 cases had a history of trauma and 15 cases had no obvious predisposing causes. All patients had limitation of shoulder flexion and abduction. Anteroposterior and lateral X-ray films of the shoulder and the out-let X-ray films of the supraspinous muscle were taken. According to the acromion classification of Bigliani, there were 5 cases of type I, 13 cases of type II, and 9 cases of type III. MRI images showed all patients had rupture of the rotator cuff. The examination of shoulder arthroscope showed complete rupture of the supraspinatus muscle in 27 cases and acromion impingement in 23 cases. The patients without impingement underwent tear debridement, and the patients with impingement underwent acromioplasty and resection of subacromial bursa after tear debridement. The 3-4 cm incision was made with arthroscopically assisted positioning, and the metal suture anchor was placed on the greater tubercle of humerus to repair rotator cuff.
  
  
  RESULTS
  All incisions healed primarily. All patients were followed up 13-27 months (mean, 19 months). No infection, loosening of internal fixation, and rotator cuff re-tear occurred. Pain was relieved and the results was satisfactory after operation. The shoulder range of motion (ROM) at last follow-up was significantly improved when compared with preoperative ROM (P < 0.05). The visual analogue scale (VAS) score was significantly improved from 8.0 +/- 1.8 at preoperation to 1.6 +/- 0.7 at 2 weeks after operation and 0.8 +/- 0.7 at last follow-up (P < 0.05); the University of California Los Angeles (UCLA) score of shoulder was significantly increased from 18.8 +/- 6.6 at preoperation to 32.2 +/- 3.3 at 3 months after operation and 33.6 +/- 2.1 at last follow-up (P < 0.05).
  
  
  CONCLUSIONS
  The effectiveness of arthroscopically assisted treatment of rotator cuff injury is satisfactory. However, long-term effectiveness needs further follow-up observation.
