About

Rob Pettitt is a pioneering figure in the field of surgical robotics, with a focused expertise in orthopaedic biomechanics and computer-assisted surgery. His most notable contribution is the development of a surgical robot for cementless total hip replacement, a groundbreaking achievement that directly linked preoperative imaging with intraoperative precision. In 1993, Pettitt and his team demonstrated the feasibility of this approach through 26 successful robot-assisted operations, laying the foundation for modern computer-integrated orthopaedic surgery. This work, which has garnered 42 citations, showcased how robotic systems could dramatically enhance the accuracy of bone preparation and implant placement—a critical factor in the long-term success of cementless hip prostheses. Pettitt’s research effectively merged medical imaging, robotics, and surgical planning, addressing a key challenge in orthopaedics: the need for reproducible, sub-millimeter precision in joint replacement. His contributions remain influential, cited as early proof-of-concept for robotic systems that are now integral to many orthopaedic practices worldwide. For students and researchers, Pettitt’s work exemplifies how interdisciplinary engineering can directly transform patient outcomes in surgery.
