title: FUNCTIONAL ASSESSMENT OF ARTHROSCOPIC REPAIR FOR RECURRENT ANTERIOR SHOULDER INSTABILITY.
abstract: OBJECTIVE
  To clinically and radiologically evaluate patients who underwent arthroscopic surgical treatment for anterior shoulder instability by means of the Bankart technique, using metal anchors.
  
  
  METHODS
  This was a retrospective study on 49 patients who underwent arthroscopic repair of anterior shoulder instability between 2002 and 2007. The patients were evaluated using the Carter-Rowe score and the Samilson and Prieto classification. The mean age at the time of surgery was 30 years. The mean length of follow-up was 42.7 months (ranging from 18 to 74). 85% of the patients were male.
  
  
  RESULTS
  The mean Carter-Rowe score was 83 points (ranging from 30 to 100) including 31 excellent results, 7 good, 3 fair and 8 poor. Recurrent dislocation was observed in 16% (8 patients), and 37.5% of them were of traumatic origin. Joint degeneration was present in 32.5% of the cases, including 5 cases of grade 1, 6 cases of grade 2 and 2 cases of grade 3. The average loss of external rotation was 12° and the loss of anterior elevation was 8°. There was a statistically significant relationship (p < 0.05) between arthritis and age at first dislocation, age at surgery and crackling. 92% of the patients reported high degrees of satisfaction after the procedure. Among the complications, there were two cases of stiff shoulder, one patient with prominence of the synthesis material and one case of anchor loosening.
  
  
  CONCLUSIONS
  Arthroscopic repair of anterior shoulder instability using metal anchors was shown to be effective, with a low complication rate.
