This week, Dr. Michelle Collie sits with Dr. Andrew Green, Chief, Division of Shoulder and Elbow Surgery at University Orthopedics to discuss the rotator cuff. What is a rotator cuff, what is its purpose, and how do we injure it? Dr. Green shares these answers, talks about the changes in the rotator cuff as we age, and gives advice on how to take care of your shoulder to prevent some of the most common injuries.
