Dr. Samer S. Hasan MD, PhD, FAAOS


Dr. Samer Hasan is an Orthopaedic Surgeon specializing in treating shoulder and elbow conditions at Mercy Health-Cincinnati SportsMedicine and Orthopaedic Center (CSMOC) in Cincinnati, Ohio. He specializes in treating the full spectrum of shoulder and elbow conditions, both nonoperatively and with surgery as needed. He has been the regional go-to specialist for complex shoulder conditions, including revision shoulder replacement, rotator cuff repair, shoulder instability surgery, and for the evaluation and treatment after failed shoulder surgery. Dr. Hasan’s overriding goal is to provide compassionate and skillful evidence-based care to each and every patient presenting with a shoulder or elbow problem.

He has been a full-time orthopaedic surgeon since 2000. He is a core faculty member of the ACGME accredited sports medicine fellowship at CSMOC and co-director of the American Shoulder and Elbow Surgeons (ASES) accredited Cincinnati Shoulder and Elbow Fellowship. In addition, he is a Clinical Instructor in the Department of Orthopaedic Surgery at the University of Cincinnati College of Medicine and Chief of Orthopaedic Surgery at The Jewish Hospital. He is a fellow of the American Academy of Orthopaedic Surgeons (AAOS) and holds a Certificate of Added Qualification in Sports Medicine.

Dr. Hasan was the first shoulder and elbow surgeon in Greater Cincinnati to be invited into ASES (2006) and has been an active member of the American Shoulder and Elbow Surgeon and various other orthopaedic subspecialty societies. He has served on multiple committees and task forces for both ASES and AAOS, including Educational and Technology Committees. He is also a long-time member and consultant for Best Doctors. He is a reviewer for multiple orthopaedic journals and is a member of the Editorial Boards for Arthroscopy and for Orthopedics Today. In 2018 he was designated as one of a handful of “Elite” reviewers for the Journal of Bone and Joint Surgery, widely regarded as the leading orthopaedic journal worldwide.

He has authored over 60 peer reviewed manuscripts and book chapters and has co-edited two textbooks, one on disorders of the biceps tendon and another one on reverse shoulder arthroplasty. He has given over 200 invited lectures, including lectures and surgical instruction on 4 continents. For nearly two decades he has participated in multicenter clinical research trials and collaborated with industry on shoulder prosthesis design, surgical techniques and education.

Dr. Hasan maintains a very busy shoulder and elbow tertiary referral practice. He sees several thousand patients in the clinic and performs 450-600 shoulder and elbow surgeries annually. Through 2019 Dr. Hasan had performed over 1600 prosthetic shoulder arthroplasties, far and away the most of any shoulder replacement surgery in the Tri-state Area, as well as nearly 2000 arthroscopic rotator cuff repairs. His experienced clinical team includes Sushma Nagar, PA-C, Stephanie Cavanaugh, ATC, and his long-time medical secretary DeAnna Perkins.

When not engaged in orthopaedic practice and education Dr. Hasan enjoys playing tennis, downhill skiing, and traveling. He has visited nearly 40 countries on 6 continents and managed to drive on all 6 continents between August 2015 and December 2019. He lives with his wife and two teenage children in a 107 year-old home in East Walnut Hills.
