You are already at one of the premier knee shops in the USA. HSS is at the forefront of modern knee replacements.

Most implants and robots are tied together. The CORI robot is from Smith & Nephew which means you are likely to get a Journey II implant. The Journey II is made of oxidized zirconium and is allegedly biocompatible.

I have a magical surgeon. He is the primary inventor of the Superpath method of minimally invasive hip replacement surgery and is one of the developers of the CORI robot. Four years ago he replaced my left hip and six months ago he replaced my right knee. Both times I had no post surgery pain.

He is even the only, or one of the few, surgeons who does many bicruciate retaining implants (BCR). In 99+% of knee replacements, the surgeon removes the ACL; in many if not most the surgeon also removes the PCL. In a BCR both are retained and protected. It is a more complex procedure but it means I still have all my natural ligaments. My surgeon has been doing them for at least a decade and there is a video of him doing one at a 2020 orthopedic innovations conference.

If I couldn't have gone to Dr. Chow, HSS along with Mayo would have been my surgery selection of choice. It was an HSS surgeon at the Florida office who did Lindsey Vonn's partial knee after which she was able to compete and even win international skiing competitions.

You are in great hands.
