    Collapse Overview
    Dr. Dorr is a Professor of Clinical Orthopaedic Surgery in the Department of Orthopedic Surgery at the Keck School of Medicine of USC. He is an international leader in the field of joint replacement of the hip and knee and has contributed significantly to advances in treatment options. His pioneering research has aided in the design of widely used orthopaedic implants, as well as small incisions and the use of computer navigation for total hip replacement. An international speaker and writer, Dr. Dorr has authored a book on surgical techniques and numerous journal articles. He is a founding editor of the Journal of Arthroplasty, former editor-in-chief of Techniques in Orthopaedics and serves on the editorial boards of several other prominent journals. He is a founding member and past president of the Knee Society and the American Association of Hip and Knee Surgeons and the past president of the Hip Society. He has received the Humanitarian of the Year Award from the American Academy of Orthopaedic Surgeons for founding Operation Walk, a charitable organization that provides free hip and knee replacements in the United States and abroad. Honored as one of the Best Doctors in American for the past eight years, Dr. Dorr received his medical degree from the University of Iowa Carver College of Medicine and completed his fellowship training in orthopaedics/arthritis surgery at the Hospital for Special Surgery in New York.
