The supraspinatus tendons were cut from the footprint to create a rotator cuff tear (RCT) on both shoulders, followed by immediate repair, with a 1\u00a0mm thick tendon stump remaining on the footprint. On one side, RCR was performed by attaching the medial rotator cuff to the GT over the footprint stump layer (enthesis preservation [EP] approach). On the other side, the footprint stump and enthesis were fully removed and the footprint was decorticated. The repair was performed by attaching the medial rotator cuff onto the spongy bone surface in the footprint area (enthesis removal [ER] approach). Twelve rabbits were sacrificed at 4, 8, and 12\u00a0weeks, of which 6 were used for histological analysis and 6 for biomechanical evaluation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Histological examination revealed that in the EP group, the native enthesis healed well with the reattached cuff tendon, and continuous collagen crossed the tendon\u2010tendon interface area at 12\u00a0weeks. However, in the ER group, there was only fibrous scar tissue formation at the tendon\u2010bone interface. Biomechanical testing revealed a significantly higher load to failure (\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .001) of the RC\u2010GT structure in the EP
