Testing was performed at 0\u00b0, 20\u00b0, and 40\u00b0 of glenohumeral abduction with 30\u00b0 of external rotation under simulated balanced and unbalanced muscle loading conditions. Outcome measures included humeral rotational range of motion (ROM), superior humeral head translation, and subacromial contact pressure.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Mean graft thickness was 4.8\u2009\u00b1\u2009.2\u2009mm for xenografts and 2.1\u2009\u00b1\u2009.1\u2009mm for allografts (\n                      <jats:italic>P<\/jats:italic>\n                      \u2009&lt;\u2009 .001). Xenograft SCR preserved physiologic rotational ROM. In contrast, allograft SCR resulted in increased internal rotation at 20\u00b0 (\n                      <jats:italic>P<\/jats:italic>\n                      \u2009=\u2009.012) and 40\u00b0 of abduction (\n                      <jats:italic>P<\/jats:italic>\n                      \u2009=\u2009.001) and greater total ROM at 0\u00b0 and 40\u00b0 (\n                      <jats:italic>P<\/jats:italic>\n                      \u2009=\u2009.007) compared with the intact state. Massive tears significantly increased superior humeral translation at all angles (\n                      <jats:italic>P<\/jats:italic>\n                      \u2009&lt;\u2009.05). Xenograft SCR restored translation to near\u2010intact levels at 0\u00b0 and 40\u00b0, whereas allograft SCR showed persistently elevated translation at 0\u00b0 and 20\u00b0 (\n                      <jats:italic>P<\/jats:italic>\n                      \u2009&lt;\u2009.05). At all angles, superior translation was significantly lower with xenograft than allograft (\n                      <jats:italic>P<\/jats:italic>\n                      \u2009&lt;\u2009.05). Subacromial pressure was highest in the massive tear condition (\n                      <jats:italic>P<\/jats:italic>\n                      \u2009&lt;\u2009.001). Both grafts reduced pressure, however xenograft SCR resulted in lower values than allograft at 20\u00b0 (\n                      <jats:italic>P<\/jats:italic>\n                      \u2009=\u2009.003) and closely matched intact values at all angles.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>In a cadaveric model of irreparable rotator cuff tear, SCR using a thick porcine dermal xenograft more effectively restored shoulder biomechanics compared with a single\u2010layer HDA.

This cadaveric study suggests that a porcine dermal xenograft with sufficient thickness may provide superior restoration of glenohumeral stability and joint mechanics compared with a commonly used single\u2010layer HDA. These findings highlight the importance of graft thickness and mechanical integrity in optimizing SCR outcomes and may inform surgical decision\u2010making in clinical practice.<\/jats:p>\n
