Patients were divided into 2 groups of 40 cases each. In group 1, standard repair was performed; in group 2, microfractures of the greater tuberosity were performed to enhance tendon repair. Clinical outcome was assessed with the Disabilities of the Arm, Shoulder and Hand (DASH) score and normalized Constant score. Tendon integrity was assessed with magnetic resonance imaging. Multivariate analysis was performed to determine which predictors were independently associated with the outcome. Significance was set at\n                      <jats:italic>P<\/jats:italic>\n                      &lt; .05.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The mean follow\u2010up was 28.1 \u00b1 3\u00a0months. Seven patients were lost to follow\u2010up (2 in group 1 and 5 in group 2). Comparison between groups did not show significant differences for baseline characteristics. The mean DASH score was 28.6 \u00b1 21.3 points in group 1 and 23.3 \u00b1 20.1 points in group 2. Although the difference was not statistically significant, the confidence interval included a 10\u2010point value (minimal clinically important difference) in favor of the microfracture group. The difference in the Constant score between groups was not significant. The tendon healing rate was 52.6% in group 1 and 65.7% in group 2, without a significant difference between groups. Subgroup analysis for tear size showed that group 2 had a significantly greater healing rate than group 1 for large tears (\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .040).
