In 2005 we developed a new type of arthroscopic Bankart repair that provided double anchor footprint fixation of AIGHLC (Modified DAFF technique). The purpose of this study was to evaluate the minimum 1-year follow-up result of this technique. We retrospectively studied 53 shoulders of 52 patients. There were 42 male and 10 female patients. The average age at operation was 22.3 years old (range, 14 to 33). We inserted the medial anchor 4mm under the anterior glenoid edge at the 3.5 oclock and the lateral anchors on the glenoid at the 4 and 3 oclock to make a footprint repair of AIGHLC around the anterior glenoid rim. At the 5 and 2 Oclock we used conventional suture anchor technique. We evaluated recurrence, the postoperative range of motion, the preoperative and postoperative JSS instability score, and return to sports. One shoulder of a snowboarder experienced re-subluxation. Postoperatively, the average loss of external rotation was 9.8° with the arm at the side, and 9.0° with the arm in 90° of abduction. The average JSS instability score improved from 47.8 preoperatively to 93.9 postoperatively. 29 patients completely returned to sports, 9 patients returned partially. The short term result of arthroscopic Bankart repair with a modified DAFF technique was satisfing.
