About Me

Dr. James Gladstone is Chief of the Sports Medicine Service and Associate Professor of Orthopedic Surgery at the Icahn School of Medicine at Mount Sinai. He is a leading expert in the treatment of sports injuries, in particular, those of the knee and shoulder. His clinical practice is dedicated to helping individuals recover from injury as comfortably and expeditiously as possible. His approach is conservative by nature and whenever possible injuries are treated non-operatively. Dr. Gladstone is well versed in the benefits of physical therapy, and other non-operative modalities, and has an excellent working relationship with many physical therapists. When surgery is required, Dr. Gladstone uses the most advanced techniques in arthroscopic and other sports medicine procedures to ensure the best outcomes in the fastest time possible.

Dr. Gladstone graduated from Dartmouth College and Tufts University School of Medicine. He did his Orthopedic residency at the New York Orthopaedic Hospital of Columbia Presbyterian’s College of Physicians and Surgeons. He then did a Sports Medicine fellowship at the American Sports Medicine Institute in Birmingham, Alabama under the tutelage of Drs. James Andrews and William Clancy. During fellowship, he developed a keen understanding of the art and science of sports medicine, the treatment of high-level athletes and the most cutting-edge techniques in sports medicine surgery. Following fellowship, he joined the Department of Orthopedic Surgery at Mount Sinai where he helped develop the Division of Sports Medicine and has stayed at the forefront of his field by teaching medical students, residents, and fellows.

Dr. James Gladstone is the Medical Advisor to the US Men’s Davis Cup tennis team and orthopedic consultant for the US Open tennis tournament and NFL Officials. He currently serves as the team physician for ASA College and 4 area public high school football teams.

Dr. Gladstone remains actively involved in sports medicine research and regularly lectures and teaches at industry courses and meetings across the country. He is widely published, particularly in the area of rotator cuff surgery and anterior cruciate ligament reconstruction. He is currently involved in several clinical studies, one of which was an FDA Phase II study, where he was the principal investigator on a novel method of transplanting cartilage cells for chondral injuries in the knee joint.

He is a fellow of the American Academy of Orthopaedic Surgeons (AAOS), and a member of the Society of American Shoulder and Elbow Surgeons (ASES), the American Orthopaedic Society for Sports Medicine (AOSSM), and the International Cartilage Repair Society (ICRS).

Dr. Gladstone has a specific clinical interest in rotator cuff injuries, shoulder instability (dislocations, labral tears), ACL and meniscal injuries to the knee and articular cartilage restoration. He treats children as young as eight years old and adults of all ages. His goal is to provide patients with the best understanding of their condition to enable them to participate fully in the decision-making process. His paramount focus will always remain to provide his patients with the highest quality of care through the duration of treatment whether non-operative or surgical.
