Abstract
By a News Reporter-Staff News Editor at Robotics & Machine Learning Daily News Daily News-New research on Surgery-Arthroplasty is the subject of a report. According to news reporting originating from Sydney , Australia, by NewsRx correspondents, research stated, "Robotic tools have been developed to improve planning, accuracy and outcomes in total knee arthroplasty (TKA). The purpose of this study was to describe and illustrate a novel techniq ue for assessing the patellofemoral (PFJ) in TKA using an imageless robotic plat form." Our news editors obtained a quote from the research, "A consecutive series of 30 R-TKA was undertaken by a single surgeon utilising the described technique. at echnique to dynamically assess the PFJ intraoperatively, pre- and post-implantation was developed. A full set of data from 9 cases was then collected and reViewed for analysis. A series of dynamic PFJ tracks collected intra-operatively pre-and postimplantation are presented. Furthermore, a full assessment of PFJ ove r and under-stuffing through a 90° arc of flexion is illustrated. Finally, a pre-and post-centre of rotation for the PFJ was defined and measured. The describe d technique was defined over a series of 30 R-TKA using the described robotic pl atform. Nine cases were analysed to determine what data could be measured using the robotic platform. Intra-operative real-time data allowed a visual assessment of PFJ tracking through a range of motion of 0°-90° flexion pre- and post-impla ntation. PFJ over and under-stuffing was also assessed intra-operatively through a range of motion of 0°-90° flexion. Post-operative analysis allowed a more det ailed study to be performed, including defining a pre- and post-implantation cen tre of rotation (COR) for the patella. Defining the COR allowed the definition o f a patella plane. Furthermore, patella mediolateral shift in full extension, an d end flexion could be measured. Intra-operative assessment of the PFJ in TKA is challenging. Robotic tools have been developed to improve measurement, accuracy of delivery and outcomes in TKA."
