Global Orthopaedics at Johns Hopkins

Global Orthopaedics at Johns Hopkins (GO-JH) is an initiative to improve orthopaedic care across the world. We aim to promote safe, timely, accessible and affordable orthopaedic surgical care to achieve global health equality. We plan to do this by building partnerships in research, education and patient care within Johns Hopkins, nationally and internationally.

Hear from Our Alumni

"Hopkins has a robust global presence in every specialty, including orthopedic surgery. This was one of the reasons I chose to complete my orthopedic training at Hopkins. As part of my elective and research time in residency I spent six weeks in Kenya during my PGY3 year and another 3 weeks in Bangladesh during my PGY4 year. Both experiences were incredible and have continued to fuel my passion for global orthopedics. Only a handful of training programs offer the same caliber of international exposure and resources to trainees – this makes Hopkins an excellent and unique place to train for the globally minded surgeon."

Hear from Our Alumni

“Providing care in a LMIC is the practice of medicine in its purest form. Free from insurance companies, EHRs and the general bureaucracy of modern medical institutions. It is as fulfilling as it is reinvigorating. As a surgeon, it gives you a holistic perspective and level of humility that cannot be understood until you experience it for yourself.”

- James Mackenzie M.D.
