“Through research and diverse surgical experiences, I have seen how navigation can be used to improve patients’ outcomes following total joint replacement,” explained Dr. Vigdorchik.
“Intellijoint’s core technology has enabled a new era of surgical navigation by providing highly accurate and cost-effective measurements for implant positioning developing and commercializing smart navigation for total joint replacements, and limb length, maintaining efficiency of my workflow, respecting my implant preferences, all without the need for radiation from a CT scan or an increase in operative time.”
According to the company, “Dr. Vigdorchik has years of surgical experience with navigation and robotics and adopted Intellijoint HIP over three years ago for most of his surgical cases. Dr. Vigdorchik is fellowship trained in Adult Reconstruction and Joint Replacement at Hospital for Special Surgery, and an assistant professor of orthopedic surgery at Weill Cornell Medical College. He specializes in all types of hip surgery from hip preservation to hip resurfacing, hip replacement, and revision.”
“The need for the next generation of surgical navigation is evident through the exceptional growth and global adoption we are experiencing,” said Armen Bakirtzian, CEO and co-founder of Intellijoint Surgical. “We are excited to partner with Dr. Vigdorchik to develop new technologies and educate orthopedic surgeons on how to effectively integrate them into their practices.”
Dr. Vigdorchik told OTW, “From the beginning, Intellijoint Surgical has been focused on creating a navigation system that seamlessly integrates into my surgical workflow and provides me with a highly accurate, intraoperative measurement tool for implant positioning, leg length, and offset, making my hip replacements surgeries more reproducible. The company’s commitment to deliver improved outcomes to my patients without the need of additional radiation through X-rays or a CT scan, and without adding significant time, cost or difficulty to my procedure, is what excited me about Intellijoint HIP.”
“This improved clinical experience, combined with my passion for research and education, is what drew me to expanding my role to Scientific Advisory Board member given Intellijoint’s investment and dedication to evidence-based clinical research and development initiatives to help advance the field of hip and knee replacement surgery.”

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.
