Abstract
By a News Reporter-Staff News Editor at Robotics & Machine Learning Daily News Daily News – New research on Artificial Intelligenc e is the subject of a report. According to news reporting originating in Yunnan, People’s Republic of China, by NewsRx journalists, research stated, “The impact of extra-articular deformities (EADs) on lower limb alignment and collateral li gament integrity during total knee arthroplasty (TKA) poses significant challeng es, increasing surgical complexity. Our study aims to evaluate the influence of EADs on mechanical axis alignment and the risk of collateral ligament injury dur ing TKA using an AI-assisted surgical planning system, with the goal of minimizi ng ligament damage through precise and scientific planning.” The news reporters obtained a quote from the research from the Department of Ort hopedics, “A healthy volunteer underwent CT and MRI scans of the lower limbs. Th e scan images were imported into Mimics 20.0 software, and the reconstructed mod els were spatially aligned using 3-maticResearch 11.0 software. Using Unigraphic s NX9.0 software, 50 three-dimensional models of femoral lateral joint deformiti es with varying positions and angles were created. Finally, TKA was simulated us ing the AI JOINT preoperative planning system. The larger the deformity angle an d the closer it is to the knee joint, the more pronounced the deviation of the m echanical axis. During MA-aligned osteotomy, nine types of deformities can damag e the collateral ligaments. After adjusting the varus/valgus of the prosthesis w ithin a safe range of 3° and leaving a residual 3° varus/valgus in the lower lim b alignment, only the 25° varus and 25° valgus deformities located at 90% of the femoral anatomical axis remain uncorrected. For patients with osteoarthri tis and concurrent EAD undergoing TKA, using reconstructed 3D models of the coll ateral ligaments for preoperative planning helps visually assess collateral liga ment damage, providing a practical solution.”
