Comments: I am a retired surgeon and did my homework to find the best surgeon to do shoulder replacement. All the local orthopedists told me that they send their problems to Dr. Cheung. My experience could not have been better. I had a regional block for 3 days after surgery and had no significant pain. My return to function has been excellent and the whole experience was flawless with Dr Cheung. I cannot recommend her more highly. She is the best.
