David J. Mayman, MD, is an orthopedic surgeon specializing in hip and knee replacement, recognized internationally for his expertise in computerized and robotic techniques for joint arthroplasty. He serves as Chief of the Adult Reconstruction and Joint Replacement Service at Hospital for Special Surgery (HSS) in New York and is Professor of Clinical Orthopedic Surgery at Weill Cornell Medicine. His practice focuses on patients with arthritis of the hip and knee, including many young, active individuals seeking to return to high levels of function through technology‑enhanced surgery.

Clinically, Dr. Mayman performs a high volume of hip and knee replacements each year, with a large proportion using computer navigation and robotic assistance to optimize implant positioning, alignment, and soft‑tissue balance. His specific expertise includes primary and revision hip and knee arthroplasty, unicompartmental knee replacement, and complex cases requiring precise kinematic analysis. He integrates advanced pre‑operative imaging and three‑dimensional planning with intra‑operative navigation to improve accuracy while promoting rapid recovery pathways.

In research, Dr. Mayman has led and collaborated on translational studies evaluating computer‑assisted and robotic techniques in joint replacement, focusing on biomechanics, ligament balancing, and long‑term outcomes compared with conventional methods. His work includes developing protocols that use robotic systems and 3‑D imaging to measure functional outcomes and reduce radiation exposure, with the overarching aim of refining technology to enhance safety, reproducibility, and patient satisfaction in hip and knee arthroplasty.
