More Than 20 Years Navigation of Knee Surgery With the Orthopilot Device

Abstract Navigation of knee surgery was born in Grenoble (France) in the mid-1990s. The first total knee arthroplasty (TKA) was implanted on a human being on January 1997 and a prospective randomized study comparing computer-assisted TKA and conventional technique finished in March 1999. The results were published, leading to marketing of the Orthopilot device. In March 2001 we carried out the first high tibial osteotomy for genu varum deformity and in January 2008 we implanted for the first time a UniKA with a “light” software. The aim of this chapter is first to present the Orthopilot device and the operative technique, then the evolution of the software in order to use it for osteotomies around the knee, UniKA, and revision of Uni to TKA. Second, results of these techniques are presented, and finally, the usefulness of navigation is discussed.
