Dear Colleagues and Friends,

It is a great honor and pleasure to welcome you to the 4th Congress of the World Association against Infection in Orthopaedics and Trauma (WAIOT), to be held on July 23–24, 2025, at the Pacifico Yokohama Conference Center, Japan.

This is the first time WAIOT will be held in Japan, and we are delighted to host this global meeting in Yokohama, Japan’s second-largest city, known for its rich history and international outlook. Since opening its port in 1859, Yokohama has symbolized innovation, cultural exchange, and openness—qualities we value in international medical collaboration. I sincerely hope this inspiring setting will enhance your experience and encourage many participants to join from around the world.

The theme of the congress, “Global Collaboration Against Musculoskeletal Infection: Innovation, Evidence, and Equity,” reflects the growing need for unified, multidisciplinary strategies to address complex challenges in orthopaedic and trauma-related infections. As these infections evolve in response to new technologies, antibiotic resistance, and demographic changes, collaboration across borders becomes essential.

The congress will feature renowned international speakers, interactive sessions, and state-of-the-art research on a wide range of topics including prevention, diagnosis, treatment, and digital innovations. We aim to create a dynamic environment where clinicians, researchers, and industry professionals can share knowledge and advance patient care together.

In addition to academic enrichment, I encourage you to explore the cultural beauty of Yokohama—whether strolling through the Minato Mirai district, enjoying local cuisine, or visiting its historic landmarks. We hope your time here will be both professionally rewarding and personally memorable.

I would like to thank the WAIOT leadership, scientific committee, organizing team, and our partners and sponsors for their dedication and support. This meeting is a reflection of our shared mission: to advance global standards in orthopaedic infection care and improve outcomes for patients worldwide.

Let us come together in Yokohama to exchange ideas, build partnerships, and shape the future of this vital field. I look forward to welcoming you in person.

Warm regards,
