By a News Reporter-Staff News Editor at Robotics & Machine Learning Daily News Daily News – New research on Musculoskeletal Diseas es and Conditions - Osteoarthritis is the subject of a report. According to news reporting originating from London, United Kingdom, by NewsRx correspondents, re search stated, “Pre-operative planning in total hip arthroplasty (THA), involves utilizing radiographs or advanced imaging modalities, including computerized to mography (CT) scans, for precise prediction of implant sizing and positioning. T his study aimed to compare Three-Dimensional (3D) versus Two-Dimensional (2D) pr e-operative planning in primary THA with respect to key surgical metrics, includ ing restoration of the horizontal and vertical Center of Rotation (COR), combine d offset, and leg length.” Our news editors obtained a quote from the research from University College Lond on (UCL) Hospitals NHS Foundation Trust, “This study included 60 patients underg oing primary THA for symptomatic hip osteoarthritis, randomly allocated to eithe r robotic-arm-assisted or conventional THA. Digital 2D templating and 3D plannin g using the robotic software were performed for all patients. All measurements t o evaluate the accuracy of templating methods were conducted on the pre-operativ e CT scanogram, using the contralateral hip as a reference. Sensitivity analyses explored differences between 2D and 3D planning in patients who had supero-late ral or medial osteoarthritis patterns. Compared to 2D templating, 3D templating was associated with less medialization of the horizontal COR (-1.2 versus -0.2 m m, P = 0.002) and more accurate restoration of the vertical COR (1.63 versus 0.3 mm, P<0.001) with respect to the contralateral side. Furt hermore, 3D templating was superior for planned restoration of leg length (+0.23 versus -0.74 mm, P = 0.019). Sensitivity analyses demonstrated that in patients who had medial osteoarthritis, 3D planning resulted in less medialization of ho rizontal COR and less offset reduction. Conversely, in patients who had supero-l ateral osteoarthritis, there was less lateralization of horizontal COR and less offset increase using 3D planning. Additionally, 3D planning showed superior rep roducibility for stem, acetabular cup sizes, and neck angle, while 2D planning o ften led to smaller stem and cup sizes. Our findings indicated higher accuracy i n the planned restoration of native joint mechanics using 3D planning.”
