Twelve specimens were randomly assigned to the 2 repair groups (6 per group). A 1 \u00d7 2\u2010cm defect was created at the insertion site of the infraspinatus tendon. Two anchors were implanted 1 cm apart in the anatomic insertional area of the infraspinatus tendon. After preconditioning to 10 N, each construct was cycled between 10 and 180 N for up to a maximum of 2,500 cycles at a rate of 33 mm\/second using a materials testing machine. The number of cycles to 5\u2010 and 10\u2010mm gap formation at the repair site and mode of failure were recorded. Clinically, 10\u2010mm gap formation defines complete fixation failure. Data were evaluated using an analysis of variance with significance 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                      Mattress suture fixation had significantly higher number of cycles to 10\u2010mm failure compared with the PLLA device (\n                      <jats:italic>P<\/jats:italic>\n                      = .015).
