ONS Sports Medicine

What is Sports Medicine?

Sports medicine focuses on the diagnosis and treatment of injuries related to sports and exercise.

ONS sports medicine physicians have specialized medical training in the diagnosis and treatment  of injuries that occur during sports and exercise-related activity. After finishing a residency program in another specialty, such as orthopedic surgery or primary care, a sports medicine physician completes a fellowship program in sports medicine.

ONS sports medicine physicians have served as consulting team physicians to many professional teams including the Los Angeles Dodgers and New York Mets and they support local school athletic teams. Our sports medicine specialists treat athletes and non-athletes of all ages and have authored ground-breaking research papers.

Research studies done on athletic conditions and injuries by sports medicine physicians have led to important advances in treatments for orthopaedic conditions in people of all ages and backgrounds.
