William Macaulay, M.D.: New Chief at NYU Langone Health

Dr. Macaulay joined NYU Langone in January 2017 as the medical director for International Patient Services, a position he will continue to hold. Prior to that, Dr. Macaulay served as chief of the Division of Hip and Knee Surgery and director of the Center for Hip and Knee Replacement at NewYork-Presbyterian (NYP) at Columbia. He also served as the director of Orthopedic Surgery at NYP/Lawrence Hospital in Westchester County, and had been a member of the faculty at Columbia University Medical Center for 17 years, acting as Advisory Dean at The College of Physicians and Surgeons for 7 years.
Dr. Macaulay also serves as professor of orthopedic surgery in the Division of Adult Reconstructive Surgery, performing his surgical procedures at NYU Langone Orthopedic Hospital in Manhattan.
“We are thrilled to have Dr. Macaulay’s vast orthopedic expertise and renowned leadership spearheading NYU Langone’s Adult Reconstructive Surgery program,” says Joseph D. Zuckerman, M.D., the Walter A. L. Thompson Professor of Orthopedic Surgery and chair of the Department of Orthopedic Surgery. “Dr. Macaulay enjoys international acclaim and will apply his experience to continue to elevate our Division that is recognized for its extensive clinical, educational and academic activities.”
Dr. Macaulay obtained his medical degree from Columbia University College of Physicians and Surgeons and completed his surgery internship and orthopedic surgery residency at University of Pittsburgh Medical Center. He also completed a postdoctoral arthroplasty fellowship at the Hospital for Special Surgery in New York.
Dr. Macaulay told OTW, “Being the Founder & Director of the Center for Hip & Knee Replacement, New York Presbyterian Hospital at Columbia from 2001 to 2015 prepared me for this new role. Going forward, first, I will aim to enhance our divisional reputation nationally and internationally and increase the clinical output through enhanced efficiency (without sacrificing quality). Also, I will focus on enhancing the divisional research and educational programs.”

Discussion
This is a fascinating development. In my practice we've seen similar outcomes with the revised protocol. The key differentiator seems to be patient selection criteria. Has anyone else noticed the correlation with BMI thresholds?
Great point. I'd push back slightly on the conclusion, the sample size in the cited study is too small to draw population-level inferences. That said, the directional signal is compelling and worth a larger RCT.
We implemented a similar approach last year. Early results are promising but we're still gathering 12-month follow-up data. Happy to share our protocol if anyone is interested.
