Background: Sarcopenia is the loss of muscle mass and consequent loss of muscle function with aging. Its prevalence can reach up to 24% in the population over 65 years. Currently, it is considered an independent risk factor for falls and fractures, disability, postoperative complications, and mortality. Rotator cuff tears are known to be influenced by systemic diseases such as diabetes mellitus, hypercholesterolemia, thyroid disease, and osteoporosis. This study aimed to evaluate the prevalence of sarcopenia in patients with and without rotator cuff tears to determine if it can be considered a risk factor for this condition. Methods: This is a prospective case-control study. Between May 2017 and May 2018, 106 patients were evaluated and divided into two groups. Group 1 (cases) included 53 consecutive patients with chronic symptomatic full-thickness rotator cuff tears (mean age, 72 ± 5 years), and group 2 (controls) included 53 age- and sex-matched patients (mean age, 71 ± 6 years). The sarcopenic index was evaluated using three measurements: skeletal muscle mass, grip strength of the dominant side and gait speed. Rotator cuff pathology was evaluated with MRI in all patients.Results: No significant differences were found in baseline data and demographic factors between the groups, except for the smoking habit (p = 0.02). The prevalence of sarcopenia was not significantly different between the groups, nor were gait speed, grip strength, and skeletal muscle mass index (p = 0.15, 0.99, and 0.9, respectively).Conclusion: The prevalence of sarcopenia in patients with rotator cuff tears was similar compared with an age- and sex-matched control population. Thus, with these results, we are not able to consider sarcopenia as an independent risk factor for rotator cuff tears.
