My 79.8-year-old mother had a whole knee replacement surgery on her left leg with Dr. An two weeks ago, and she is walking with a cane already! Actually, she went grocery shopping yesterday, and then took a 30 minutes walk at the Queens Botanical Garden! Choosing Dr. An is the best decision we have ever made! My mother already reached out to Dr. An regarding the knee surgery on her right leg! Dr. An and his team are the true experts in the field, and they are extremely detail oriented! Dr. An is patient, kind, and truly care about his patient's well-being! Saying he is a GOOD Orthopedic surgeon is an understatement! He is one of the VERY BEST surgeons in NYC!
