Meet your surgeon
Dr. Hayk Stepanyan, MD.
Raised in Yerevan, Armenia, and in Los Angeles since his teens, Dr. Stepanyan is a board-certified, dual fellowship-trained orthopedic surgeon. He focuses on minimally invasive, muscle-sparing hip and knee replacement, robotic-assisted MAKO surgery, and anatomic and reverse shoulder replacement, alongside arthroscopy and sports medicine — with a special interest in orthopedic trauma and fracture care.
His goal is simple: improve your quality of life and return you to the activities you enjoy. Outside the OR, you'll find him exercising, traveling and spending time with his family.
Board certified by the American Board of Orthopaedic Surgery. Dr. Stepanyan operates at Adventist Health Glendale, Glendale Memorial Hospital, Adventist Health White Memorial and White Memorial Montebello, Providence Saint Joseph Medical Center and Avalon Surgery Center.

Special interests
Less invasive.
More you.
Modern joint replacement is changing what recovery looks like. Dr. Stepanyan's work centers on three ideas.
Robotic-assisted precision.
Minimally invasive technique.
Outpatient joint replacement.
Whether one of these approaches is right for you is a conversation for your consultation — every plan starts with your joint, your health and your goals.
Patient stories
In their words.
“He told me he wouldn't let go of my hand until my left knee was healed and I could walk again. Now I am healed — I can resume my life as before.”
“Dr. Stepanyan stands out for his compassion, honesty and his expertise. Thank you for your exceptional dedication to your patients.”
“I had the pleasure of having Dr. Stepanyan as my surgeon regarding my shoulder. He is very attentive and takes very good care of his patients.”
