The function of the long head of the biceps tendon (LHBT) in the glenohumeral joint generates controversy among researchers. For some, the tendon does not have a significant function in the shoulder, while others consider it acts as a depressor of the humeral head and a stabilizer of the joint. These functions may be enhanced in cases of rotator cuff injuries, where compensatory hypertrophy and/or instability of the LHBT can occur, which can also be a source of pain. One of the imaging techniques used for diagnosing these injuries is ultrasound. Initially, G. Walch proposed tenotomy of the LHBT in massive rotator cuff tears to improve pain and, in some cases, shoulder function. Currently, many authors advocate tenotomy of the LHBT as an adjunct to rotator cuff repair to avoid postoperative pain. However, there is no evidence that this procedure improves the clinical outcomes of isolated rotator cuff repair. Based on the pathophysiology of the LHBT associated with rotator cuff injuries and the current trend to perform tenotomies in conjunction with cuff repair, the objectives of this doctoral thesis project were: To compare the clinical and imaging outcomes of arthroscopic rotator cuff repairs with and without LHBT tenotomy. To analyze the position and cross-sectional area of the LHBT in the bicipital groove using ultrasound in cases with and without tenotomy.
