Dr. Kevin Choo
Kevin J. Choo, MD, is a board-certified orthopedic surgeon who specializes in primary hip and knee replacement for the treatment of degenerative osteoarthritis, inflammatory arthritis, avascular necrosis, hip dysplasia, and post-traumatic arthrosis. He is fellowship-trained in direct anterior hip replacement, the use of computer- and robotic-assisted technology, and partial knee replacement. Dr. Choo specializes in opioid-sparing protocols, rapid recovery surgical techniques, and outpatient total hip and total knee replacements.
Dr. Choo completed his undergraduate education at Stanford University. He then earned his medical degree from the University of Chicago and completed his internship and residency at UCSF (University of California- San Francisco). He received fellowship training in Adult Reconstruction and Joint Replacement at the Rothman Institute in Philadelphia, PA. Dr. Choo has presented and published on such topics as the biology of bone healing, the reduction of opioid use after orthopedic surgery, periprosthetic joint infection management, and partial joint replacement. Dr. Choo was named an Emerging Leader by the American Orthopaedic Association (AOA). He is a reviewer for the Journal of the American Association of Orthopaedic Surgeons (JAAOS) and the Journal of Orthopaedic Trauma (JOT). He has been a Castle Connolly ‘Top Doctor’ since 2022.
Dr. Choo serves as a co-director of Arthroplasty at Greenwich Hospital.
Dr. Choo grew up in Buffalo, NY and was an avid musician and athlete. He was selected to the county, regional, and All-State Orchestras for classical trombone. He was an All-State and Academic All-American in lacrosse, and played lacrosse at Stanford University, where he served as team captain. He enjoys cooking, photography, running/cycling, and spending time with his family.
