The rotator cuff is responsible for many of the motions your shoulder performs. In this episode, NYU Langone orthopedic surgeon Joseph D. Zuckerman, MD, and primary care sports medicine doctor Dennis A. Cardone, DO, explain the muscles and tendons that make up the rotator cuff and some of the most common problems that can occur, including tendinitis, tendinosis, and full and partial tears. The doctors also talk through nonsurgical and surgical treatments and when each is appropriate.
