Dr. Miller: Rotator Cuff Surgery

I was in excruciating pain, waking up three times a night with a stabbing pain in my right shoulder that would not go away. I was fortunate to have Dr. Miller repair and make my shoulder better than new with a rotator cuff surgery . Best of all, I am totally pain free. My range of motion and strength are perfect. Dr. Miller is personable and is very empathetic. His surgical skills are of the highest caliber. ONS experience from pre op to full recovery was flawless. Thank You Dr. Miller.

Dr. Miller: Reverse Shoulder Replacement

Dr. Miller has performed two reverse shoulder replacements for me over a two & a half year period. Both  were extremely successful with no pain and a great range of motion. There is nothing I wish to physically do that I cannot. He is to be lauded for his competence, professionalism, warmth and superb patient skills. (comment from Health Grades)

Dr. Kowalsky: Shoulder

I was so pleased with Dr. Kowalsky‘s professionalism. He was very thorough and spoke to me in “real talk” so that I understood what was going on with my shoulder. I also liked the fact that he told me if I had any questions or problems to feel free and call the office. I called him about a medication I was taking and his nurse got right back to me. I highly recommend Dr. Kowalsky. (comment from Health Grades)

Dr. Delos: ACL and Meniscus

Dr. Delos is not only an exceptional doctor, but he is caring and compassionate. My daughter had a torn ACL and Meniscus and was scheduled to compete in Disney. Dr. Delos worked with her to assure she could take the mat and compete prior to her surgery. He was factual but understanding of the opportunity she had in going to Disney. I would recommend him to EVERYONE in need of his specialty. (comment from RateMD) 

Dr. Delos: Knee Replacement

Young, innovative, and on the cutting edge of his specialty. Dr. Delos replaced both my knees and I had wonderful results with minor pain, minimized by his phenomenal anesthesia formula. Best of all, the lack of external stitching (using medical glue instead) eased the healing process and left no ugly scarring. I could not ask for better results. Highly recommended by HSS and deservedly so. Thanks Dr. Delos. (comment from RateMD)

Dr. Cunningham: Shoulder and Knee

Dr. Cunningham has been my doctor for many years and has done a successful meniscus repair 6-7 years ago. More recently he helped me with a stiff shoulder 3 years ago, (advising excellent stretching exercises that worked) and has been very helpful with my knee and ankle problem. On my latest visit he was very effective in assessing the problem with my knee by recommending and administering a cortisone shot (which had excellent results) and laying out a plan for the next six months so I can return to golf. As I age he is an important medical partner. (F.B.)

He was a nice person too. – (Patient satisfaction survey)

Dr. Cunningham: Knee

Cos Cob resident J.M. was 24 when he was playing basketball with friends and tore his ACL. An x-ray at Stamford Hospital indicated no broken bones but Jason was advised to see an orthopedist. The next day, he visited James Cunningham, MD. A physical examination determined he had most likely ruptured his ACL. An MRI confirmed the diagnosis. “An avid basketball player and all-round athlete, J.M. was a good candidate for an ACL reconstruction,” said Dr. Cunningham who, in the surgery last April, used part of his patient’s patellar tendon to reconstruct the ACL. The surgery also included work on a partially torn meniscus. The surgery lasted an hour and a half and J.M. went home later the same day. His recovery was steady and his pain was managed with Advil. After five days he began a physical therapy program, which he followed three days a week for the first month and gradually reduced over the following few months. His knee regained full flexibility and before long he returned to playing basketball with his friends. (J.M.)
