Rotator Cuff Tear Size: Could It Be Influenced by the Presence of One or More Diseases Capable of Altering the Peripheral Microcirculation?

Background: To date, it is not well known which systemic pathologies most frequently afflict patients with rotator cuff tear (RCT) and whether the coexistence of two or more pathologies can affect the lesion size. Therefore, we analyzed our database relative to a large group of patients who recently underwent rotator cuff repair. Methods: A total of 527 patients with full-thickness RCT were enrolled. For each patient, we checked the presence of at least one of diabetes, venous system diseases, cardiovascular diseases, hypercholesterolemia, blood hypertension, thyroid diseases, and a smoking habit. Patients were subdivided according to risk factors into five groups, representing those who had zero, one, two, three, and four or more risk factors, respectively. Statistical analysis was performed. Results: In total, 37% of our patients had no risk factors; 28% had one risk factor (arterial hypertension, smoking habit, and hypercholesterolemia were the most frequent); 23% had two risk factors (the hypertension/hypercholesterolemia association was the most frequent); and 8% suffered from three pathologies (the diabetes/arterial hypertension/hypercholesterolemia association was the most frequent). Comparing the cuff tear severity in patients without and with at least one risk factor, we observed that tear size increased in those with at least one risk factor. Conclusions: A total of 63% of patients with rotator cuff tears were either smokers and/or had at least one pathology capable of altering the peripheral microcirculation. Hypertension and hypercholesterolemia were the most frequent. Tear severity significantly increased with the presence of at least one risk factor.
