About

Luigi Zanna is an orthopedic surgeon and researcher whose work centers on advanced surgical techniques for knee arthroplasty, with a particular focus on restoring mechanical alignment and optimizing component positioning in complex cases. His major contributions include pioneering the use of accelerometer-based navigation systems in total knee arthroplasty for patients with extra-articular deformities, a challenging subset where traditional alignment methods often fall short. His landmark 2019 paper on this topic has garnered 37 citations, underscoring its influence in the field. More recently, Zanna has advanced robotic-assisted unicompartmental knee replacement, demonstrating that setting tibial component rotation based on femoral landmarks—rather than relying solely on tibial bony anatomy—achieves more congruent knee kinematics. This 2023 work, though still accumulating citations (9 to date), represents a significant step toward personalized, image-based surgical planning. Zanna’s research bridges the gap between navigation technology and clinical outcomes, offering reproducible solutions for deformity correction and implant longevity. His achievements highlight a commitment to precision and innovation, making him a notable voice in the evolution of computer-assisted orthopedic surgery.
