Among them, 82 of 92 patients who met the inclusion and exclusion criteria were available for follow-up. Fascia lata autografts augmented with LARS ligament (LARS with PET; Corin Group) were used in 43 patients (LARS group), and fascia lata autografts with PP mesh augmentation were used in 39 patients (mesh group). Clinical outcomes were evaluated preoperatively and at a final follow-up by a visual analog scale for pain score and range of motion along with the American Shoulder and Elbow Surgeons (ASES) score, University of California, Los Angeles (UCLA) score, and Constant-Murley score (CMS). Radiological outcomes were assessed according to the rotator cuff arthropathy and acromiohumeral distance stages. Graft integrity and muscle fatty infiltration were evaluated by magnetic resonance imaging.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      Both groups showed significant improvement in clinical and radiological outcomes at the final follow-up.
