Biographical details

Professor Johnson is a graduate of the University of Sydney where he also obtained a Masters and PhD degrees. He completed residency training in surgery at Colorado State University, and since then has worked in academia as an orthopaedic specialist in the USA and UK for a further 20 years. From 2000 to 2008, Ken was the Professor of Orthopaedics at Ohio State University, which has an international reputation for fracture management and joint replacement surgery.

In addition, Prof Johnson organizes the AO courses on fracture treatment in Columbus Ohio and Sydney and is a past president of AO VET (an international foundation dedicated to fracture treatment in animals). He recently returned to The University of Sydney as a Clinical Professor, Director of Orthopaedics and Chief of Surgery. He has specialist qualifications in surgery as a Diplomate of American College of Veterinary Surgeons, a Diplomate of European College of Veterinary Surgery, as well as being a Fellow of Australian College of Veterinary Scientists. Prof Johnson is the author of over 100 clinical and research publications on orthopaedics. He co-authored the textbook - ¿Atlas of Surgical Approaches to Bones and Joints in the Dog and Cat¿ together with Professor Donald Piermattei. In his spare time, Ken is an Editor in Chief of the international journal ¿ ¿Veterinary and Comparative Orthopaedics and Traumatology¿.
