title: Long term results of arthroscopic Bankart repair for traumatic anterior shoulder instability.
abstract: BACKGROUND
  The arthroscopic method offers a less invasive technique of Bankart repair for traumatic anterior shoulder instability. We would like to report the 2 year clinical outcomes of bio-absorbable suture anchors used in traumatic anterior dislocations of the shoulder.
  
  
  METHODS
  Data from 79 shoulders in 74 patients were collected over 4 years (2004-2008). Each patient was followed-up over a period of 2 years. The patients underwent arthroscopic Bankart repair using bio-absorbable suture anchors for their shoulder instability. These surgeries were performed at a single institution by a single surgeon over the time period. The patients were assessed with two different outcome measurement tools. The University of California at Los Angeles (UCLA) shoulder rating scale and the Simple Shoulder Test (SST) score. The scores were calculated before surgery and at the 2-year follow-up. The recurrence rates, range of motion as well post-operative function and return to sporting activities were evaluated.
  
  
  RESULTS
  SST results from the 12 domains showed a significant improvement from a mean of 6.1 ± 3.1 to 11.1 ± 1.8 taken at the 2-year follow-up (p < 0.0001). Data from the UCLA scale showed a Pre and Post Operative Mean of 20.2 ± 5.0 and 32.4 ± 4.6 respectively (p < 0.0001). 34 had excellent post-operative scores, 35 had good scores, 1 had fair score and 3 had poor scores. 75% of the patients returned to sports while 7.6% developed a recurrence of shoulder dislocation or subluxation.
  
  
  CONCLUSIONS
  Arthroscopic Bankart repair with the use of suture anchors is a reliable treatment method, with good clinical outcomes, excellent post-operative shoulder motion and low recurrence rates.
