Meet your surgeon

Dr. Hayk Stepanyan, MD.

Raised in Yerevan, Armenia, and in Los Angeles since his teens, Dr. Stepanyan focuses on joint preservation, arthroscopy and minimally invasive replacement of the shoulder, hip and knee — 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.

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.
