Biography
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. His clinical interest also includes revision hip and knee surgery for the treatment of failed joint replacement due to infection, loosening, or recurrent dislocation.
Dr. Choo 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 is also a 2023 Castle Connolly Top Doctor.

5 Star Review on HealthgradesPatient
“I had been suffering when walking for three year ,because of pain from arthritis. Finally, I couldn’t walk even one block. I decided to get an anterior hip replacement. Dr. Choo was my surgeon. He always answer my questions kindly and patiently. In the hospital, everyone was so kind and took care of me so well. After surgery, I recovered so quickly. My X ray 2 week after looked very good. Actually after surgery I didn’t need much medication for my pain. Now, after only about a month, I can walk smoothly. I am amazed. I thank God for giving my life again through Dr. Choo’s help. Dr. Choo has terrific skills as a surgeon. He is also very kind and thoughtful.”
5 Star Review on HealthgradesPatient
“My recent anterior hip replacement surgery was so successful that here I am, 6 weeks later, back to my normal active routine. It's as if I never had a hip issue. I can attest to this fabulous achievement since I can compare it to the posterior procedure used on my other hip several years ago. The recovery time has been one third the length of that operation. Dr. Choo's surgery follow-up phone calls and office visits give me total confidence in him as a person as well as a highly skilled professional. “
5 Star Review on HealthgradesPatient
“I met Dr Choo when I wanted to start physical therapy for advanced arthritis in my right hip. Dr Choo reassured me that PT is a first good step whether or not you have hip replacement & he said while hip replacement was medically indicated in my case , it was my decision on when & how to proceed. After PT & a year of normal life, my arthritis advanced & I decided to move forward with right anterior hip replacement at ONS. Dr Choo's professionalism is very reassuring & he takes time to fully explain the medical condition, medical treatment, anterior hip replacement process & recovery including anesthesia. I was confident with Dr Choo & am thrilled with the result and the pre and post surgery process. The ONS team is fantastic & Dr Choo is wonderful. I am 2 weeks after surgery and navigating easily with a cane & no pain. I enthusiastically recommend Dr Choo and regard him as an expert, trusted medical provider. He is simply the best!! “
