 During arthroscopic rotator cuff infraspinatussupraspinatus repair, biceps tendon lesions are frequently encountered. However, the most optimal treatment of the diseased long head of the biceps LHB tendon during rotator cuff repair remains a topic of debate: tenotomy or tenodesis. The hypothesis is that there is no difference in functional outcome between LHB tenotomy and LHB tenodesis when performed in adjunct to arthroscopic rotator cuff repair.
