Hoag Orthopedic Institute Celebrates 10th Anniversary

  • Posted On:

Hoag Orthopedic Institute (HOI) will officially celebrate its 10th anniversary this November. In 10 years, HOI has grown into the largest orthopedic hospital on the west coast, earning many national accolades affirming its high quality of care. HOI has performed more than 148,00 procedures since 2010 and is the highest volume provider of joint replacements in California for the past eight years.

Established in 2010 through a unique partnership between Hoag Memorial Hospital Presbyterian and a group of visionary Orange County orthopedic physicians, HOI is a specialty hospital that focuses exclusively on orthopedics.

In its 10 year history, HOI has grown to include a specialty hospital in Irvine, two medical clinics in Orange County and ambulatory surgery centers located in Newport Beach, Mission Viejo, and Orange. Most recently HOI has expanded operations to Los Angeles County with a fourth ambulatory surgery center in Marina del Rey.

Four Orange County orthopedic surgeons, Carlos Prietto, M.D., James Cailloutte, M.D., Robert Gorab, M.D., and Alan Beyer, M.D, were the principle forces to organize and build HOI. In 10 years, HOI’s medical staff has grown to more than 80 orthopedic surgeons and a medical staff of more than 300.

“Every single employee and physician contributed to HOI’s incredible patient outcomes, accomplishments and successes,” says Robert Gorab, M.D., chief medical officer of Hoag Orthopedic Institute. “HOI has delivered outstanding results because the HOI team is outstanding.”

At its inception, HOI’s vision was to become a trusted leader in orthopedics both locally and nationally. HOI’s vision was realized over the course of 10 years, after earning several prestigious awards including recognition as the number one orthopedic hospital in Orange County for hip and knee replacement by U.S. News and World Report as well as Press Ganey’s “Pinnacle of Excellence” and “Guardian of Excellence” awards. Additionally, the Centers for Medicare & Medicaid Services (CMS) has awarded HOI a five-star patient experience rating for five consecutive years.

HOI received Consumer Reports’ highest rating for hip and knee surgery and was ranked first place by Nerd Wallet for knee and hip procedures. HOI has also received the highest possible rankings from Becker’s Hospital Review for orthopedic programs and its low readmission rates. HOI was recognized as a top performer in the treatment of fragility fractures and bone healthcare by the American Orthopaedic Association. Moreover, its unique and effective model of care was profiled in a case study authored by researchers from Harvard Business School.

“HOI began with a vision to create a new model of musculoskeletal care to deliver exceptional outcomes with a commitment to continuous improvement, transparency and value,” added Jennifer Mitzner, CEO of HOI. “I’m truly honored to be a part of what Hoag Orthopedic Institute has become and the impact HOI has had on the community.”

HOI routinely gives back to the community, providing charitable care, volunteering for local high school sporting events, offering free community lectures and educational events. Additionally, Dr. Alan Beyer and Dr. Jonathon Kaplan provide free sports medicine advice on the HOI sponsored weekly radio show “Doctor in the Dugout” on KLAA-AM.
