About

Dr. Nao Shibanuma is a leading orthopedic surgeon and researcher specializing in the precision and outcomes of robotic-arm assisted joint arthroplasty. Her work focuses on total hip arthroplasty (THA) and total knee arthroplasty (TKA), with a particular emphasis on improving implant placement accuracy and early postoperative recovery. Dr. Shibanuma’s major contributions include demonstrating that robotic-arm assisted THA can achieve precise cup positioning even in complex cases like developmental dysplasia of the hip (DDH), a finding supported by 34 citations. She has also shown that robotic THA offers superior early clinical recovery compared to image-based navigated THA (28 citations) and identified key factors—such as surgical approach and pelvic tilt—that influence cup placement accuracy (28 citations). In knee surgery, her work reveals that robotic-arm assisted TKA reduces tibial bone resection without increasing flexion contracture risk. With over 95 total citations across her most-cited papers, Dr. Shibanuma’s research is shaping the future of computer-assisted orthopedics, providing critical evidence for surgeons adopting robotic technologies to enhance patient outcomes.
