Harlan C. Amstutz, M.D. is the founding director of the Joint Replacement Institute, Professor Emeritus and former Chief of Orthopaedic Surgery at the University of California at Los Angeles. Dr. Amstutz is recognized worldwide as a preeminent orthopaedic surgeon and researcher in the field of joint replacement.
Unlike conventional total hip replacement (THR), hip resurfacing is conservative in that the femoral head and neck of the hip joint are not removed nor is bone removed from the femur. In the case of surface replacement, less bone is also removed from the acetabulum as compared to conventional THR since no polyethylene liner is used.

Thomas Schmalzried, M.D.
Thomas P. Schmalzried, M.D., Associate Director of the Joint Replacement Institute at St. Vincent Medical Center, is a board-certified orthopaedic surgeon specializing in the diagnosis and treatment of diseases of the adult hip and knee, with a focus on total joint replacement. The author of over one hundred scientific manuscripts, he is a three-time recipient of the John Charnley Award for pioneering research in joint arthroplasty.
Schmalzried is on the editorial review board of several scientific journals and is the Joint Replacement Section Editor for Orthopedics Today, the most widely read orthopaedic periodical. He has served on the Board of Directors of the Western Orthopaedic Association (1996-97), the American Academy of Orthopaedic Surgeons (1998-2000), the Orthopaedic Research Society (2000-present) and the Association of Arthritic Hip and Knee Surgeons (2000-present).
Dr. Schmalzried attended Stanford University on a basketball scholarship and was a 3-year varsity letterman. He graduated in 1980 with honors and distinction, and was elected to membership in the Phi Beta Kappa academic society. Dr. Schmalzried attended UCLA Medical School and was elected to membership in the academic medical society, Alpha Omega Alpha. He did his internship in surgery and residency in orthopaedics at UCLA. In 1985-86, Dr. Schmalzried was a research fellow in joint replacement, sponsored by the National Institutes of Health (NIH). Following his residency at UCLA in 1990-1991, Dr. Schmalzried was the Hip and Implant Fellow at Harvard University and an Assistant in Orthopaedic Surgery at the Massachusetts General Hospital.
In addition to his academic pursuits, Dr. Schmalzried is a recognized expert in orthopedic managed care and he is a managing partner of California Orthopedic and Sports Medicine Associates, a specialty IPA and managed care consulting firm.
