About

Sergio Romagnoli is an orthopedic surgeon and researcher whose work centers on advancing robotic-assisted total knee arthroplasty (RA-TKA), with a particular focus on the ROSA Knee System. His research addresses critical questions in joint replacement surgery, including the accuracy of bone cuts in both coronal and sagittal planes, and the practical challenges of integrating new technology into the operating room. Romagnoli’s studies have demonstrated that robotic systems can achieve high precision in alignment and component sizing, while also showing that surgical time can be rapidly reduced as surgeons progress through the learning curve—a key finding for encouraging adoption of RA-TKA. Though his most-cited papers are recent (2025), they have already accumulated several citations, signaling growing interest in his work. His contributions are particularly valuable for surgeons and trainees seeking evidence-based guidance on the implementation of robotic tools in total knee arthroplasty, and his findings help bridge the gap between technological promise and clinical reality.
