Our lunch symposium at the 46th SICOT Orthopaedic World Congress in Kyoto, held from September 29 to October 1, 2026, was very well attended. It was a pleasure for us to bring together leading experts and enthusiastic participants for an interactive discussion on complex revision surgeries of the hip and acetabulum. Special thanks go to our outstanding speakers – Prof. Roman Pfeifer, M.D., and Prof. Hans-Christoph Pape, M.D., from the University Hospital of Zurich; Prof. Marc Hanschen, M.D., from TUM Klinikum Rechts der Isar and Prof. Nobuhiko Sugano, M.D., from the Kawanishi City Medical Center in Osaka – who shared their experiences and valuable insights with us.
