                <jats:title>Methods<\/jats:title>\n                    <jats:p>Forty patients undergoing arthroscopic RCR for full\u2010thickness rotator cuff tears were enrolled and prospectively randomized to receive a screw\u2010type (19 patients) or coil\u2010type (21 patients) suture anchor for the medial row during repair. All repairs used a transosseous\u2010equivalent configuration with footprint anchors laterally. Marrow elements released during surgery were evaluated for 9 cytokine markers (insulin\u2010like growth factor 1, fibroblast growth factor 2, bone morphogenetic proteins 7 and 2, platelet\u2010derived growth factors AA and BB, epidermal growth factor, transforming growth factor beta1, and vascular endothelial growth factor). Postoperative computed tomography scans were performed at 6 months. Range of motion, strength, and validated patient\u2010reported outcome measures (Simple Shoulder Test, Single Assessment Numeric Evaluation, visual analog scale, and American Shoulder and Elbow Surgeons scores) were gathered before the operation and at 6 months and 1 year postoperatively.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Bone mineral density surrounding the coil\u2010type anchor was significantly greater than that surrounding the screw\u2010type anchor (\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .005). Bone mineral density values within the coil\u2010type and screw\u2010type anchors were comparable (\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .527); however, a larger amount of total bone mineral mass (in milligrams) was shown within the coil\u2010type anchor owing to its larger volume (\n                      <jats:italic>P<\/jats:italic>\n                      &lt; .01).

Postoperatively, no statistically significant difference was found between groups for clinical outcome measures at 6 months or 1 year. Retear and complication rates were similar between groups (\n                      <jats:italic>P<\/jats:italic>\n                      &gt; .05).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Both the coil\u2010type and screw\u2010type anchors can be reliably used for RCR and produce similar clinical outcomes.
