Using three standard portals, single\u2010row repair was performed at the 2, 3, and 5 o\u2019clock positions, and DAFF with the suture bridging technique was conducted at the 4 o\u2019clock position. MRI was performed preoperatively and at 6\u00a0months postoperatively. Patients with follow\u2010up periods of\u2009\u22651 year were included in the present study and clinically evaluated at the final follow\u2010up. The morphology at the 2 and 4 o\u2019clock positions on radial MRI slices was compared between the preoperative and 6\u2010month postoperative scans, and the footprint of the repaired capsulolabral complex at 6\u00a0months postoperatively was compared between the 2 and 4 o\u2019clock positions.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The average follow\u2010up period was 19.5\u2009\u00b1\u20096.2\u00a0months.

The University of California at Los Angeles and Rowe scores at the final follow\u2010up were 34.5\u2009\u00b1\u20091.0 points and 97.2\u2009\u00b1\u20095.7 points, respectively, representing significant improvements over the preoperative scores (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.01). Although the capsulolabral complex at 6\u00a0months postoperatively was firmly repaired at both the 2 and 4 o\u2019clock positions compared to its preoperative state, the footprint of the restored capsulolabral complex was wider at the 4 o\u2019clock position than at the 2 o\u2019clock position (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.01).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Additional DAFF at the 4 o\u2019clock position improved the glenohumeral stability and function of the shoulder joint.
