Dr. Daniel Wiznia is an Assistant Professor of Orthopaedic Surgery and an Assistant Professor of Mechanical Engineering & Materials Science who specializes in reconstructive surgery of the hip and knee. He has expertise in total hip replacements, as well as in partial knee replacements and total knee replacement surgeries. He also specializes in revision hip and revision knee replacements.

Dr. Wiznia is from Connecticut, and he graduated from Amity High School in Woodbridge. He completed his bachelor’s degree in mechanical engineering at Yale University while working with several medical device startup companies. After graduation, he worked as a health care consultant for McKinsey & Company.

Dr. Wiznia received his medical degree with honors in research at Weill Cornell Medical College. He completed his orthopaedic surgery residency at Yale School of Medicine, followed by an adult reconstruction fellowship at New York University, Hospital for Joint Diseases at NYU School of Medicine. In addition, Dr. Wiznia completed an adult reconstruction fellowship at the Insall Scott Kelly Institute for Orthopaedics and Sports Medicine.

For complex cases, Dr. Wiznia performs robotic- and computer-navigated total joint replacement surgery, emphasizing minimally invasive and tissue-preserving procedures. When indicated, he utilizes patient-specific instruments and custom implants. He employs the surgical approach that is best for the patient, and is skilled in performing total hip replacements from either the anterior approach or the posterior approach. As a resident at Yale, Dr. Wiznia was mentored by Kristaps Keggi, MD, who is considered a pioneer in the anterior approach for total hip replacements.

In addition to his clinical work, Dr. Wiznia has developed research programs in total joint replacement, health care policy, and injury prevention. His findings have been reported in many professional peer reviewed publications, and his research has been presented at regional and national meetings. He is a member of the American Academy of Orthopaedic Surgeons, the American Association of Hip and Knee Surgeons, and the American Society of Mechanical Engineers.

Dr. Wiznia is a conservative physician who believes that less is more. He forms a partnership with his patients, explains his thoughts fully and works with them every step of the way. He takes time to talk to his patients about how he arrived at his diagnosis and explains all of the available treatment options. He manages conditions without surgery whenever possible. Dr. Wiznia’s ultimate goal is to return his patients to the activities they enjoy, with the intention of improving their quality of life.
