Cigarette smoking intensifies tendinopathy of the LHBT. A microscopic study after arthroscopic treatment

Smoking has a damaging effect on the musculoskeletal system, which was presented by authors in the rotator cuff and Achilles tendons studies; however, there are a lack of data about the effect of smoking on disorders of the long head of the biceps tendon (LHBT), particularly at the microscopic level. The purpose of this study was to investigate the effect of the tobacco smoking on the histopathologic alterations of the LHBT. Thirty-six patients with preoperatively diagnosed tendinopathy of the LHBT were referred to the Orthopaedics Department. All patients underwent arthroscopic treatment with further macroscopic and microscopic evaluation of biceps tendon samples. The active and former smokers were characterised by more advanced degenerative process of the tendinous tissue; moreover, it was intensified in the group of former smokers. Subjects who smoke more than 20 cigarettes per day also had more advanced microscopic alterations. The most severe microscopic alterations occurred in the former smokers who used tobacco for more than 20 years. However, the non-smokers group revealed moderate degeneration in all LHBT samples. Tobacco smoking is an important risk factor of the LHBT disease, which essentially intensifies the degeneration of the tendinous tissue.
