A Prospective Randomized Study Comparing the Interference Screw and Suture Anchor Techniques for Biceps Tenodesis

Background:Several methods are used to perform biceps tenodesis in patients with superior labrum-biceps complex (SLBC) lesions accompanied by a rotator cuff tear. However, limited clinical data are available regarding the best technique in terms of clinical and anatomic outcomes.Purpose:To compare the clinical and anatomic outcomes of the interference screw (IS) and suture anchor (SA) fixation techniques for biceps tenodesis performed along with arthroscopic rotator cuff repair.Study Design:Randomized controlled trial; Level of evidence, 2.Methods:A total of 80 patients who underwent arthroscopic rotator cuff repair with SLBC lesions were prospectively enrolled and randomly divided according to the tenodesis method: the IS and SA groups. Functional outcomes were evaluated with the visual analog scale (VAS) for pain, American Shoulder and Elbow Surgeons (ASES) score, Simple Shoulder Test (SST), Constant score, Korean Shoulder Score (KSS), and long head of the biceps (LHB) score at least 2 years after surge...
