BACKGROUND The disorders of the long head of the biceps (LHB) are a common cause of shoulder pain. Among all surgical treatments used to resolve LHB tendon disorders, tenodesis is one of the most frequent.The literature describes many arthroscopic and open surgical techniques, but there is still no general consensus on the standard of care.The purpose of this paper is to describe the clinical and functional outcomes of our totally intra-articular "Needle-Anchor" arthroscopic tenodesis technique applied to isolated LHB tendinopathy. MATERIALS AND METHODS We present a case study of 60 patients with an isolated LHB tendon disorder, treated with our totally intra-articular Needle-Anchor arthroscopic technique between 2011 and 2013.All patients were assessed preoperatively with University of California, Los Angeles (UCLA) and Constant-Murley (CS) shoulder scores and the visual analogue scale (VAS) for subjective pain assessment. Imaging studies were performed through magnetic resonance imaging. Patients were reevaluated with a follow-up at 3 and 12 months with VAS, UCLA, and CS scores.Statistical analysis was performed with the Mann-Whitney score where values of P
