title: Use of grafts in rotator cuff re-rupture.
abstract: OBJECTIVE
  Rotator cuff re-ruptures appear in 38-65% of cases. In order to reduce this rate, many studies have been performed using different types of biomaterial for purely mechanical aims (re-inforce the suture) and/or biological agents (growth factor transporterts). The aim of this study is to review 22 cases treated with xenografts and analyse various current alternatives.
  
  
  METHODS
  A descriptive and retrospective study was conducted using the variables of age, sex, laterality, time of surgery, involvement in MRI, number of anchors, and final mobility results on the Constant and the University of California Los Angeles (UCLA) validated scales.
  
  
  RESULTS
  The study included 22 patients, with a mean age of 51.7±4.6 years. A mean of 2 anchors were used and 13 patients were treated with a porcine intestinal submucosa implant, 6 with equine pericardium, and 3 with porcine dermis. Final results were: 37.6±13 points for the Constant test, and 16.9±3.9 points on the UCLA scale. The follow up was 36±10.2 months.
  
  
  CONCLUSIONS
  In our experience, xenografts could provide good functional results and they would be a surgical alternative to tendon transfers in cases of massive tears. Further studies should be conducted with other biomaterials.
