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 from Chongqing, People’ s Republic of China, by NewsRx journalists, research stated, “Optimal sagittal a lignment of the femoral prosthesis is critical to the success of total knee arth roplasty (TKA). While robotic-assisted TKA can improve alignment accuracy, the e fficacy of default femoral alignment versus individualized alignment remains und er scrutiny.” The news correspondents obtained a quote from the research from Second People’s Hospital, “This study aimed to compare the differences in prosthetic alignment, anatomical restoration, and clinical outcomes between individualized femoral sag ittal alignment and default sagittal alignment in robotic-assisted TKA. In a pro spective randomised controlled trial, 113 patients (120 knees) underwent robotic -assisted TKA were divided into two groups: 61 with individualized femoral flexi on (individualized alignment group) and 59 with default 3-5° flexion (default al ignment group). The individualized alignment was based on the distal femoral sag ittal anteverted angle (DFSAA), defined as the angle between the mechanical and distal anatomical axes of the femur. The radiographic and clinical outcomes were compared. Despite similar postoperative femoral flexion angles between groups ( P = 0.748), the individualized alignment group exhibited significantly lower inc idences of femoral prosthesis extension and higher rates of optimal 0-3° prosthe sis flexion (9.8% vs. 27.1%, P = 0.014,78.7% vs. 55.9%, p = 0.008, respectively). The individualized alignment g roup also demonstrated more favourable changes in sagittal anatomy, with higher maintenance of postoperative anterior femoral offset within 1 mm (54.1% vs. 33.9%, P = 0.026) and posterior condylar offset within 1 mm and 2 mm (44.3% vs. 25.4%, p = 0.031,73.8% vs. 50.8%, p = 0.010, respectively). Although slight improvement in the Hospital for Special Surgery Knee Score (HSS) at three months was observed (P = 0.045), it did not reach a minimal clinically important difference.”
