Although arthroscopic techniques for anterior shoulder instability have generally yielded good results and decreased the morbidity, a recurrence has been the most serious postoperative complication. In 2005 we developed a new type of arthroscopic Bankart repair: the double anchor footprint fixation (DAFF) technique. It simulates a conventional open transosseous Bankart repair. The purpose of this study was to introduce this technique and evaluate the short-term surgical results. We investigated 45 shoulders (34 males and 11 females) which underwent a DAFF technique. The mean age at operation was 24.1 years old and the mean postoperative follow-up period was 13 months. DAFF technique was consisted of a trough preparation and double anchor footprint fixation in order to make a larger area of the footprint repair. The shoulders had their internal rotation immobilized for 3 weeks after the operation. We evaluated the postoperative range of motion, return to sports, recurrence and JSS shoulder instability score. Regarding the postoperative range of motion, elevation recovered early, but external rotation could not recover so early. More than 12 months after the operation, 23 patients completely returned to sports, 5 patients returned partially. There was no recurrence of a dislocation. The JSS-SIS improved from 52.9 preoperatively to 94.9 postoperatively. An arthroscopic Bankart repair with a DAFF technique could be performed successfully. We need a long-term follow-up and to study more about the time of starting ROM exercises.
