Sixty patients with end-stage knee osteoarthritis were randomized to receive either robotic arm-assisted total knee arthroplasty (raTKA; n=28) or conventional manual total knee arthroplasty (cmTKA; n=32). Outcomes of interest included postoperative pain measured by Visual Analog Scores (VAS), functional recovery assessed by Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores, active and passive range of motion (aROM, pROM), imaging evaluations of component alignment, and inflammatory markers such as C-reactive protein (CRP) and erythrocyte sedimentation rate. Outcomes were assessed at 1 and 3 days postoperatively, and at 1, 3, and 12 months. Overall, the results of the study revealed that raTKA provided better functional recovery and more accurate prosthesis positioning without additional pain or trauma compared to cmTKA. The findings suggest that raTKA may improve the precision and outcomes of TKA.
