In this episode, Robin sits down with Dr. Aaron Hofmann, an orthopedic surgeon whose four decades of innovation in large joint reconstruction have shaped the field in ways still felt today. Dr. Hofmann shares his journey from growing up on a small farm in Medina, North Dakota, to becoming a pioneering force in cementless fixation and knee system design. He reflects on how a childhood spent fixing everything himself, from farm equipment to electrical systems, laid the foundation for a career defined by mechanical thinking and creative problem solving.

The conversation covers the development of the ultracongruent insert, the asymmetric tibial component, and the Natural Knee system, tracing how each innovation grew directly out of clinical challenges Dr. Hofmann encountered in practice. He also shares the story of Operation Walk Utah, the humanitarian chapter he founded to bring total joint replacement to underserved patients in El Salvador, and how the constraints of that work, limited inventory, minimal instruments, and improvised solutions, directly informed the design philosophy behind Total Joint Orthopedics.

Together, Robin and Dr. Hofmann explore how TJO's universal knee, the Klassic® Knee System, with its single-instrument tray system, is built around the principle that less is more and addresses the challenges of ASCs. Dr. Hofmann discusses 10-year clinical outcomes, kinematic studies, and ongoing bone ingrowth research. The episode closes with a look ahead, and Dr. Hofmann's view on the future of orthopedics – making excellent care simpler, more accessible, and available to far more of the world's patients.
