Board Certified Orthopaedic Surgeon Sports Medicine & Total Joint Arthroplasty

Sunny C. Cheung, MD
Sunny C. Cheung, MD

As an orthopaedic surgeon specializing in shoulder, hip and knee arthroscopy and reconstruction, Dr. Sunny Cheung brings a high level of orthopaedic care to Newport Beach orthopaedics. In addition to attending Harvard undergrad, he completed an orthopaedic 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 orthopaedic 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 Orthopaedic Surgeons annual meeting.

Dr. Cheung believes most orthopaedic 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 orthopaedic injury and feels fortunate to be in a field where we have the technology to restore patients back to their full potential.
