Bethesda, Maryland (November 9, 2022) - Barry Waldman, MD, a joint replacement surgeon with The Centers for Advanced Orthopaedics (CAO) with expertise in hip, knee and shoulder replacements, has completed the first successful knee surgery using Medacta’s NextAR technology in the state of Maryland. NextAR is a revolutionary augmented reality-based surgical application for total knee replacements, first introduced to the United States in 2020.

NextAR’s technology platform is designed and engineered with artificial intelligence and machine learning that make pre-operative CT-based planning and analysis efficient and precise. Surgeons can visualize surgical actions and information in real time to improve the user and patient experience. The NextAR Augmented Reality Surgical Platform leverages patient-specific, unique real-time data to complement operative workflow more efficiently.

 “I am incredibly proud to be at the cutting-edge of next-generation surgical technology,” said Dr. Waldman. “Our goal at CAO is to offer our patients the highest quality care, and that includes through new and innovative approaches. NextAR is changing the way surgeons operate and I am honored to be the first to leverage this technology here in Maryland.”

 Dr. Waldman is an internationally renowned orthopaedic surgeon with nearly 30 years of experience. He practices at CAO’s OrthoMaryland care center, treating patients in Baltimore, Lutherville and Owings Mills, Maryland. Dr. Waldman specializes in hip, knee and shoulder surgery, with a special focus on minimally invasive joint replacement and arthritis surgery. He developed a minimally invasive hip replacement approach and minimally invasive knee and hip replacement systems. In addition to treating patients in private practice, Dr. Waldman is Director of the Center for Joint Preservation and Replacement at the Rubin Institute for Advanced Orthopaedics and serves as a Clinical Instructor of Orthopaedic Surgery at the Johns Hopkins School of Medicine, where he earned his medical degree and completed his internship and residency training.
