Matt is the founder of GenuSurg and serves as the company's senior design engineer. Matt has authored numerous peer-reviewed journal publications relating to total and unicondylar knee arthroplasty, and in particular those that examine how patient, surgical technique, and implant factors have influenced outcomes of each procedure. Matt has an encyclopedic knowledge of past and contemporary knee arthroplasty systems, which is deeply rooted in his spending the past 2 decades examining retrieved implant collections at various sites around the country.
