Macaulay will oversee care at the Joint Replacement Center at New York-Presbyterian/Lawrence, as well as other orthopedic surgery programs. He will perform surgery there as well as at Presbyterian/Columbia University Medical Center and will also see patients in Bronxville, Tarrytown and Manhattan.
Macaulay is the director of the Center for Hip & Knee Replacement and co-chief of the division of hip and knee reconstruction at NewYork-Presbyterian Hospital/Columbia University Medical Center. At Columbia University College of Physicians and Surgeons, he is a professor of clinical orthopedic surgery and director of the clinical hip and knee fellowship.
“Our goal will be to enhance the already amazing care provided by NewYork-Presbyterian/Lawrence orthopedic surgeons by blending world-class surgeons and state-of the-art technology with the community feel of this Bronxville treasure, ” Macaulay said. “We want residents to have the best of both worlds close to their homes.”

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.
