Dr. David Mayman is one of a handful of national experts in computer navigation in hip and knee replacement surgery. He performs over 700 computer-navigated joint replacement surgeries a year. “I believe that in the future all joint replacement will be done with better tools," he says. "Computer guides give more consistent alignment, with no bigger incision.” Dr. Mayman studied human kinesiology in his native Canada, and trained in orthopedic sports medicine as well as joint-replacement surgery. His typical patient is an active 40-60 year old with an arthritic or pre-arthritic condition of the hip or knee, who wants to get back to previous activities - not just walk around the block. Whatever the patient’s age, Dr. Mayman is concerned with getting people back to their lives through minimally invasive surgery. As Co-Director of Computer Assisted Surgery at HSS, Dr. Mayman has a strong research background in computer navigation with a primary interest of incorporating new technologies into arthroplasty that can make it easy to achieve good surgical techniques, and therefore, good patient outcomes.
