Construct failure often occurs at the suture-tendon interface.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Purpose\/Hypothesis:<\/jats:title>\n                    <jats:p>The purpose of this study was to compare the biomechanical properties of 3 types of rotator cuff repair (RCR): a nonaugmented transosseous-equivalent (TOE) repair, a conventional patch\u2013augmented TOE repair, and a TOE repair augmented with a polyethylene terephthalate (PET) patch that directly interlocks with the underlying tendon across its entire interface. It was hypothesized that interlocked patch augmentation of RCR is biomechanically superior to conventional TOE.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Study Design:<\/jats:title>\n                    <jats:p>Controlled laboratory study.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>A total of 18 ovine infraspinatus tendons were detached, repaired (with TOE), and tested in 3 groups (n = 6): (1) nonaugmented TOE, (2) conventional patch\u2013augmented TOE, and (3) interlocked patch\u2013augmented TOE. In the second group, a commercial synthetic polyester patch was attached to the tendon via No. 2 FiberWire sutures and laterally attached to the humerus using No. 2 FiberWire sutures and 2 knotless anchors. In the third group, an interwoven patch-tendon interface was created using a microblade to push the fibers of the patch directly into the underlying tissue and to the humerus as described above. Each specimen underwent cyclic loading, followed by pull-to-failure testing. Ultimate tensile strength, cyclic and linear stiffness, peak-to-peak elongation, and gap formation were measured.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      Direct patch interlocking resulted in significantly higher tendon purchase during pull to failure (587 \u00b1 109 N vs 222 \u00b1 48 N and 211 \u00b1 52 N) as well as cyclic stiffness testing (44 \u00b1 3 N\/mm vs 25 \u00b1 2 N\/mm and 29 \u00b1 2 N\/mm) compared with the conventional patch\u2013augmented and nonaugmented TOE, respectively (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt; .0001 for all comparisons).
