Larry Dorr

Dr. Lawrence D. Dorr is medical director of the Dorr Arthritis Institute at Centinela Hospital Medical Center in Inglewood, California. He is a world leader in hip and joint replacement surgery and research. His research has aided in the design of widely used orthopedic implants.

Dorr has performed more than 4,000 hip and knee replacements in the past decade alone. His career as an orthopedic surgeon and clinical professor at the University of Southern California and other Los Angeles hospitals and clinics has earned him the reputation as one of the top surgeons and researchers in his field. He lectures internationally and publishes six to 10 scientific articles each year.

In 1994 Dorr started Operation Walk, an international mission in which operating crews travel to developing countries to perform knee and hip replacements and teach native doctors how to perform the operations. His team has traveled to Russia, Nepal, China, India, the Philippines, Cuba, Nicaragua, Peru, and beyond—helping more than 850 people. They perform two missions a year in California to operate on uninsured patients. Dorr received the 2005 Humanitarian of the Year Award from the American Academy of Orthopedic Surgeons for his work with Operation Walk.

Dorr was born in Storm Lake, Iowa, the son of a Methodist minister. He attended high school in Des Moines and graduated from Cornell in 1963 with a B.A. in English. One of his Cornell professors and mentors, Dr. Francis Pray, had a total hip replacement and today walks on a hip Dorr designed. While at Cornell, Dorr was a member of the 1961 conference championship football team.

Dorr received an M.S. degree in 1965 and an M.D. in 1967, both from the University of Iowa. He received Cornell’s Distinguished Achievement Award in 2003 and currently serves on the Cornell College Board of Trustees. Dorr provided the vision for Dimensions: The Center for the Science and Culture of Healthcare.
