Hirotsugu Muratsu

About

Hirotsugu Muratsu is a leading orthopedic researcher specializing in total knee arthroplasty (TKA), with a focused expertise in robotic-assisted surgical techniques and intraoperative soft tissue balance. His work bridges the gap between advanced robotics and clinical outcomes, particularly in achieving optimal ligament tension during knee replacement surgery. Muratsu’s most cited paper (2023, 16 citations) compares handheld robotic systems to conventional alignment guides for bi-cruciate stabilized TKA, demonstrating superior prosthetic orientation and limb alignment with robotic assistance. This study has become a key reference for surgeons adopting less invasive robotic tools. Earlier, he developed a pioneering robotic tensor device (2013, 3 citations) that enables real-time, precise measurement of soft tissue balance during TKA—a critical factor in preventing postoperative knee laxity and reducing revision surgery rates. Though his citation counts are modest, Muratsu’s contributions are foundational in the niche field of robotic orthopedics, directly influencing surgical practice by providing objective, data-driven methods for ligament balancing. His work is particularly valuable for researchers and clinicians seeking to enhance TKA outcomes through technological innovation, positioning him as a key figure in the evolution of computer-assisted knee surgery.
