Book appointment

As an orthopedic surgeon specializing in shoulder, hip and knee arthroscopy and reconstruction, Dr. Sunny Cheung brings a high level of orthopedic care to Newport Beach Orthopedics. In addition to attending Harvard undergrad, he completed an orthopedic sports surgery fellowship at University of California, San Francisco where he gained expertise in the latest procedures in cartilage, tendon and ligament restoration. Dr. Cheung’s research has appeared in many national and international publications, and he has written for orthopedic textbooks both in the United States and
internationally. He has also taken part in many research projects, and has presented his findings on rotator cuff pathology at the American Academy of Orthopedic Surgeons annual meeting.

Dr. Cheung believes most orthopedic problems can be treated non-operatively and that surgery is the last resort. Nothing is more satisfying to him than seeing a patient recover from an orthopedic injury and feels fortunate to be in a field where we have the technology to restore patients back to their full potential.
