When robots fail - The local experience with robotic-assisted joint replacement surgery

Abstract

Introduction: Robotic-assisted joint replacement surgery offers individualised planning and improved accuracy in implant positioning. However, problems may occur during planning and bone bed preparation. This study gathers the local experience in robotic-assisted joint replacement surgery, along with its possible problems and solutions. Methods: A 33-item questionnaire was sent out to via email to members of the Adult Joint Reconstruction Chapter of HKOA. Participants were invited to comment on four aspects of robotic-assisted joint replacement. The first part of the questionnaire looks into the general feedback and satisfaction. Remaining areas investigated the potential problems and corresponding solutions during the planning phase of the surgery and mechanical or software failures during surgery. Results: From our preliminary data, 10 surgeons participated in the survey. They were generally satisfied with roboticassisted surgery with a score of 8.13 of 10. They also gave positive response towards the accuracy (8.75 of 10) and ease of use (7.88 of 10) of robotic-assisted joint replacement surgery. Of the 10 participants, seven surgeons reported problems with operative plan, two surgeons reported problems with software, and six surgeons reported mechanical problems that interrupted surgery. Discussion: Despite bringing convenience to surgeons in achieving accurate, patient-specific joint replacement, roboticassisted surgery also brings in new technical problems that requires unique solutions. These problems may steepen the learning curve for surgeons who are new to the technology.
