Clinical outcomes, including range of motion, visual analog scale for pain, Constant Shoulder (CS), and University of California Los Angeles (UCLA) score, were evaluated at 3, 6, and 24 months postoperatively. The retear rate and tendon integrity were assessed at 3, 6, and 24 months follow-up using magnetic resonance imaging, and risk factors for retear were analyzed.</div></div><div><h3>Results</h3><div>Of 181 patients enrolled, 20 (11%) had retears and 161 (89%) had no retears. The retear group was significantly older (<em>P</em> = .037) and had more large or massive tears (<em>P</em> = .044), larger tear sizes on magnetic resonance imaging (coronal plane: 29.9 ± 14.9 mm vs. 21.6 ± 12 mm, <em>P</em> = .005; sagittal plane: 23.7 ± 12.1 mm vs. 17.9 ± 9.4 mm, <em>P</em> = .013), and greater fatty infiltration (<em>P</em> &lt; .001). Both groups achieved good clinical outcomes, but the retear group showed significantly lower CS and UCLA scores at 6 and 24 months (CS score: 72.4 ± 9 point vs. 78.6 ± 8.6 point at 6 months [<em>P</em> = .004] and 81.2 ± 11.1 point vs. 86.3 ± 9.6 point at 24 months [<em>P</em> = .032]; UCLA score: 25 ± 2.6 point vs. 27.3 ± 3.5 point at 6 months [<em>P</em> = .005], 28.7 ± 4.6 point vs. 30.9 ± 3.7 point at 24 months [<em>P</em> = .018]) and higher visual analog scale scores at 24 months (21.5 ± 12 vs. 7.8 ± 7.7, <em>P</em> = .021).
