Propensity score matching (1\u2010to\u20101) was performed between a no\u2010releasing group (Group I) and CHL\u2010releasing group (Group II). In total, 76 patients in each group were matched. Clinical outcomes were assessed and compared between the two groups, including range of motion (ROM) and visual analogue scale for pain (pVAS) at postoperative 3\u00a0months, 6\u00a0months, and 1 year. The integrity of the repaired tendon was assessed at 1\u2010year follow\u2010up using either magnetic resonance imaging or ultrasonography.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>External rotation (ER) at side at postoperative 3\u00a0months in Group II was better than that in Group I (48.6\u00b0\u2009\u00b1\u200911.6\u00b0 vs. 38.4\u00b0\u2009\u00b1\u200913.0\u00b0, <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001). When evaluating only patients with a small\u2010to\u2010medium sized tear at postoperative 3\u00a0months, ER at side was 49.8\u00b0\u2009\u00b1\u200910.9\u00b0 in Group II versus 37.8\u00b0\u2009\u00b1\u200913.1\u00b0 in Group I (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001). In patients with a large\u2010to\u2010massive sized tear, however, there was no significant difference in ER at side at postoperative 3\u00a0months (n.s.). There was no significant difference in ROM and functional scores at postoperative 6\u00a0months and 1 year, and there was no significant difference in healing failure rate (6 cases in Group I (7.9%), 2 cases in Group II (2.6%); n.s.). No complications of the CHL release procedure occurred.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>In arthroscopic rotator cuff repair, CHL release from the coracoid process without creating a rotator interval defect could be an effective and safe method to prevent early postoperative stiffness, especially ER at side in patients with a small\u2010to\u2010medium sized tear. Therefore, CHL release can be used as a selective procedure to prevent postoperative stiffness in patients that may benefit from this procedure with decreased preoperative ER compared to the normal side.<\/jats:p><\/jats:sec><jats:sec><jats:title>Level of evidence<\/jats:title><jats:p>Level
