In groups 1 to 3, the gluteus medius tendon was detached from the greater trochanter. Group 1 underwent no repair. In groups 2 and 3, repair was performed acutely during the index procedure immediately after tendon detachment, using intraosseous tunnels and 5-0 Prolene sutures; in group 3, an autologous fascia lata graft was incorporated as an onlay augmentation. At 4 weeks, animals were euthanized for biomechanical and histological evaluation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      All tendons failed at the tendon-bone interface.
