  1. Female population: Mean age 63.93 ± 7.05; Mean age at surgery 65.41 ± 6.94; Mean age at menopause 51.27 ± 1.95; Mean BMI 27.73 ± 4.24; Mean duration of symptoms 22.67 ± 20.93 months. Full-thickness rotator cuff tears were classified into the numbers of tendons torn: small lesions (< 1 cm of tear and < 1 tendon involved); medium lesions (1–3 cm of tear and 1 tendon involved); large (3–5 cm of tear and 2 tendons involved); massive (> 5 cm of tear and > 2 tendons involved). Partial-thickness rotator cuff tears were graded in a binary fashion as either grade 1 (less than 50% torn) or grade 2 (more than 50% torn) and according to the side torn (either articular or bursal)
