Patients were categorized as nonsmokers (1172 patients); former smokers stratified by cessation duration of &lt;1 year, 1 to &lt;3 years, 3 to &lt;5 years, and \u22655 years (454 patients); or current smokers (276 patients). After 1:1:1 propensity score matching based on age, employment status, tear size, and fatty infiltration, the records of 276 patients per group were analyzed. The visual analog scale, Subjective Shoulder Value, American Shoulder and Elbow Surgeons score, University of California at Los Angeles score, and range of motion were used to compare functional outcomes. Six-month postoperative magnetic resonance imaging assessed structural integrity using the Sugaya classification.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      At the 2-year (range, 23-27 months; mean, 24.5 \u00b1 1.0 months) follow-up evaluation, clinical scores and range of motion had significantly improved (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt; .001 for all) in all groups without significant intergroup differences.
