Symptom duration, prevalence of diabetes, tear size, tendon involvement (type 1, supraspinatus; type 2, supraspinatus and subscapularis; and type 3, supraspinatus and infraspinatus; type 4, supraspinatus, subscapularis, and infraspinatus), and fatty infiltration (Goutallier stages 0-4) were evaluated. A retear was appraised using magnetic resonance imaging, and clinical outcomes were assessed using range of motion, the Korean Shoulder Scoring System (KSS), and the University of California, Los Angeles (UCLA) shoulder score.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>The stiff group showed a significantly lower retear rate (1\/39, 2.6%) than the nonstiff group (47\/320, 14.7%) ( P = .043). There were significant differences in symptom duration (7.4 \u00b1 6.6 vs 15.0 \u00b1 23.7 months, respectively; P &lt; .001), mediolateral tear size (18.9 \u00b1 8.9 vs 24.1 \u00b1 12.0 mm, respectively; P = .002), tendon involvement (94.9%, 5.1%, 0.0%, and 0.0% vs 85.3%, 6.9%, 7.8%, and 0.0%, respectively; P = .048), and fatty infiltration of the subscapularis (66.7%, 33.3%, 0.0%, 0.0%, and 0.0% vs 31.9%, 61.3%, 5.6%, 1.3%, and 0.0%, respectively; P &lt; .001) and teres minor (74.4%, 20.5%, 5.1%, 0.0%, and 0.0% vs 47.2%, 48.8%, 3.8%, 0.0%, and 0.3%, respectively; P = .007) between the stiff and nonstiff groups. Preoperatively, the stiff group showed significantly worse forward flexion (95.9\u00b0 \u00b1 23.6\u00b0 vs 147.7\u00b0 \u00b1 4.2\u00b0, respectively; P &lt; .001), external rotation (17.4\u00b0 \u00b1 10.1\u00b0 vs 51.6\u00b0 \u00b1 12.1\u00b0, respectively; P &lt; .001), and internal rotation (L5 vs L2, respectively; P &lt; .001) and lower KSS (52.1 \u00b1 13.8 vs 66.3 \u00b1 13.5, respectively; P &lt; .001) and UCLA scores (18.7 \u00b1 4.8 vs 22.5 \u00b1 4.5, respectively; P &lt; .001) than the nonstiff group. However, these differences became insignificant from 3 months postoperatively for forward flexion ( P &gt; .05) and KSS ( P &gt; .05) and UCLA scores ( P &gt; .05), from 1 year postoperatively for external rotation ( P &gt; .05), and at the last follow-up for internal rotation ( P &gt; .05). A multiple logistic regression analysis revealed that only mediolateral tear size (odds ratio, 1.043; P = .014) and type 2 tendon involvement (odds ratio, 4.493; P = .003) were independent predictors of a retear.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>RCTs concomitant with shoulder stiffness showed a smaller mediolateral tear size, anterosuperior tendon involvement, and less severe fatty infiltration preoperatively and better repair integrity postoperatively than RCTs without stiffness.
