Patients included those with a synthetic patch inserted as an interposition graft for large and\/or irreparable rotator cuff tears with a minimum 2-year follow-up. Standardized assessment of shoulder pain, function, range of motion, and strength was performed preoperatively, at 6 and 12 weeks, and at 6 months and \u22652 years. Radiograph and ultrasound were performed preoperatively, at 6 months, and \u22652 years.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>At a mean of 36 months, 58 of 68 eligible patients were followed up, and 53 of 58 (90%) patches remained in situ. Three patches failed at the patch-tendon interface, while 1 patient (2 shoulders\/patches) went on to have reverse total shoulder replacements. Patient-ranked shoulder stiffness ( P &lt; .001), frequency of pain with activity and sleep ( P &lt; .0001), level of pain at rest and overhead ( P &lt; .0001), and overall shoulder function improved from bad to very good ( P &lt; .0001) by 6 months. Supraspinatus (mean \u00b1 SEM: 29 \u00b1 16 N to 42 \u00b1 13 N) and external rotation (39 \u00b1 13 N to 59 \u00b1 15 N) strength were the most notable increases at the \u22652-year follow-up ( P &lt; .0001). Passive range of motion also improved by 49% to 67%; forward flexion, from 131\u00b0 to 171\u00b0; abduction, from 117\u00b0 to 161\u00b0; external rotation, from 38\u00b0 to 55\u00b0; and internal rotation, from L3 to T10 ( P &lt; .0001) preoperatively to \u22652 years. The most improvement in passive range of motion occurred between 12 months and \u22652 years. The mean (SD) Constant-Murley score was 90 (12), while the American Shoulder and Elbow Surgeons score was 95 (8).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>At 36 months postoperatively, patients who had synthetic patches used as tendon substitutes to bridge irreparable rotator cuff defects reported less pain and greater overall shoulder function as compared with preoperative assessments. They demonstrated improved range of passive motion and improved strength. The data support the hypothesis that the technique of using a synthetic PTFE patch to bridge a large and\/or irreparable tear has good construct integrity and improves patient and clinical
