The preliminary foam block model intended to mimic osteoporotic bone using a 0.12 g\/mL foam material. Half of the foam block models were first filled with injectable calcium phosphate bone substitute material (CP\u2010BSM), whereas the other half were not augmented with CP\u2010BSM. Each specimen was then instrumented with a threaded suture anchor. The same technique and process was performed in a matched cadaveric humeri model. Testing then consisted of a stepwise, increasing axial load protocol for a total of 40 cycles. If the anchor remained intact after cyclic loading, the repair was loaded to failure. The number of completed cycles, failure load, and failure modes were compared between groups.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Average pull\u2010out strength for suture anchor with CP\u2010BSM in the osteoporotic foam block model was significantly higher at 332.68 N \u00b1 47.61 compared with the average pull\u2010out strength of suture anchor without CP\u2010BSM at 144.38 N \u00b1 14.58 (\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .005).
