From this cohort, 24 patients treated with the in-continuity technique and 24 treated with the margin disruption technique were included. Ten-year MRI findings (subscapularis Goutallier grade, tendon integrity, and supraspinatus tear progression) and clinical outcomes (active range of motion [ROM], visual analog scale [VAS] pain score, Subjective Shoulder Value [SSV], American Shoulder and Elbow Surgeons [ASES] score, and University of California, Los Angeles [UCLA] score) were compared. A subgroup analysis was performed to evaluate long-term structural outcomes according to early tendon healing quality assessed on 6-month MRI.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      A total of 48 patients were followed for a mean of 11.9 \u00b1 1.2 years. Radiologically, among patients confirmed to have an intact repair at 6 months, none progressed to a retear during long-term follow-up. However, during the 10-year follow-up period, supraspinatus tears developed in a higher proportion of patients in the margin disruption group (11\/24 vs 2\/24;\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = .003).
