Derek F. Amanatullah, M.D., Ph.D.

Associate Professor of Orthopaedic Surgery

BioDerek F. Amanatullah, M.D., Ph.D., is an internationally recognized expert in hip and knee replacement. He helps patients with advanced arthritis and complex joint problems regain mobility and confidence. In addition to primary hip and knee replacements, he is frequently sought out for difficult revision surgeries, often fixing complications such as infection, instability, or persistent pain from prior procedures.

Dr. Amanatullah focuses on what truly lowers surgical risk: the skill, preparation, and coordination of the surgical team. He believes patients deserve care that relies on evidence and expert technique rather than placing the burden solely on weight or other patient factors. This patient-centered approach was highlighted by The New York Times.

As a researcher, he discovered an important new way certain infections can remain “hidden” in the body, shaping how surgeons diagnose and treat joint infections. His impact on the field earned him induction into The Knee Society, an honor held by fewer than 200 surgeons worldwide. Patients choose Dr. Amanatullah for his precision, innovation, and commitment to providing the safest, most effective joint care possible.
