Denis Nam, M.D., a board certified orthopedic surgeon specializing in hip and knee reconstruction, replacement, revision, partial knee replacement and minimally invasive surgery, will now be offering his experience and talent at Midwest Orthopaedics at Rush (MOR).
Denis Nam, M.D. Joins Midwest Orthopaedics at Rush

As indicated in the December 6, 2016 news release, Dr. Nam received his Bachelor of Arts degree in economics and pre-medicine from Yale University and his medical degree from Northwestern University Feinberg School of Medicine. He performed his residency in orthopedic surgery, followed by his adult reconstruction and joint replacement fellowship at Hospital for Special Surgery. He then went on to complete his Master of Science degree in Clinical Research and Investigation at Washington University School of Medicine, St. Louis, Missouri. He has a special interest in clinical outcomes research following hip and knee replacement, the implementation of new technologies and surgical techniques in total joint replacement, implant wear in total joint replacement and partial knee replacement.
Asked what he is excited about as far as this new position, Dr. Nam told OTW, “I’m most looking forward to joining an outstanding group of physicians and team members who are committed to providing excellent patient care, while also pursuing clinical research to improve patient outcomes.”
“I intend to focus primarily on clinical outcomes following total knee arthroplasty, in particular to determine the impact of component alignment on knee function and stability. We have several ongoing projects that will utilize both radiographic and gait analyses to hopefully quantify patient-reported knee stiffness and stability, with the hopes of improving outcomes through focused rehabilitation protocols and implant design.”

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.
