Dr. Scott Hacker, M.D., M.S., F.A.A.O.S.
Dr. Scott Hacker is a board-certified, fellowship-trained orthopedic surgeon specializing in sports medicine, knee and shoulder surgery, cartilage restoration, arthritis treatment, and robotic-assisted joint replacement. A native San Diegan, Dr. Hacker returned to San Diego in 2003 after completing advanced orthopedic training and has since cared for athletes, active adults, and patients of all ages throughout the region.
Dr. Hacker’s practice focuses on advanced arthroscopic techniques, reconstructive surgery of the knee and shoulder, treatment of sports-related injuries, joint preservation, and alternatives to joint replacement when appropriate. He is certified as a Mako robotic joint replacement surgeon and has performed thousands of joint replacement procedures. He is also one of a select group of orthopedic surgeons with specialized experience in cartilage repair and restoration.
A unique part of Dr. Hacker’s background is his training in both engineering and medicine. He earned his undergraduate degree in bioengineering from the University of California, San Diego, graduating Magna Cum Laude, and later completed a master’s degree in bioengineering and orthopedic biomechanics at the UC San Diego Jacobs School of Engineering. His graduate work focused on the biomechanical properties of meniscal tissue, cartilage, and orthopedic structures. This engineering foundation continues to influence his approach to orthopedic surgery, joint mechanics, implant technology, cartilage preservation, and clinical innovation.
Dr. Hacker completed medical school at the University of California, Irvine School of Medicine, followed by general surgery and orthopedic surgery training at the University of Washington in Seattle. His residency training included experience at Harborview Medical Center, Seattle Children’s Hospital, the Veterans Administration Medical Center, and Virginia Mason Medical Center. He also completed an orthopedic research fellowship at UC San Diego.
After residency, Dr. Hacker was selected for the prestigious Orthopedic Sports Medicine Fellowship at the internationally recognized Steadman-Hawkins Clinic in Vail, Colorado. There, he trained under Dr. Richard Steadman and Dr. Richard Hawkins in advanced knee and shoulder surgery while caring for athletes and patients from around the world.
Dr. Hacker has extensive experience caring for athletes at every level, from high school and recreational athletes to collegiate, professional, and Olympic competitors. He has served as a Team Orthopedic Surgeon for the United States Olympic Team at the Olympic Training Center in Chula Vista, California. He was also previously affiliated with the Denver Broncos, Colorado Rockies, and U.S. Olympic Ski Team.
In addition to his surgical practice, Dr. Hacker is actively involved in orthopedic innovation and clinical research. He serves as a Principal Investigator at Horizon Clinical Research, where he helps evaluate new treatments, technologies, and applications in orthopedics. His consulting practice includes clinical trial design, medical monitoring, research oversight, and participation in regulatory submissions for device and drug approval.
Dr. Hacker continues to teach arthroscopic shoulder and knee surgery and serves as a clinical instructor for the San Diego Sports Medicine Fellowship Program. He is board certified by the American Board of Orthopedic Surgery and is a member of the American Academy of Orthopedic Surgeons.
Above all, Dr. Hacker and his team are committed to providing thoughtful, individualized orthopedic care. Their goal is to help patients understand their condition, review all appropriate treatment options, and return to the activities that matter most to them.
