Core Viewpoint - The successful completion of the first HX robotic arm-assisted total knee arthroplasty at the Fourth Medical Center of the Chinese People's Liberation Army signifies a significant advancement in the clinical application of domestic orthopedic surgical robots, moving from "technological breakthroughs" to "clinical popularization" [1][4]. Group 1: Surgical Procedure and Patient Background - The patient, a 61-year-old woman, had a 10-year history of osteoarthritis in both knees, with worsening pain and limited mobility in the right knee over the past two years, necessitating surgical intervention [3]. - Previous treatments, including sodium hyaluronate injections, failed to alleviate her symptoms, leading to the decision to use the HX robotic arm for the surgery due to the high precision and functional recovery requirements [3]. Group 2: Technology and Innovation - The HX robotic arm, developed by Yuanhua Intelligent Technology's subsidiary, is the only domestic company that has achieved full-chain independent research and development of core components for orthopedic surgical robots [4]. - The system utilizes preoperative CT data for 3D reconstruction, quantifying lower limb alignment and osteotomy range to create a personalized surgical plan [6]. - During the surgery, the optical tracking system provided real-time navigation with sub-millimeter accuracy, ensuring that the osteotomy thickness, prosthetic angle, and limb alignment met physiological requirements [6]. Group 3: Clinical Outcomes and Implications - The HX robotic arm maintained prosthetic position accuracy within sub-millimeter levels, significantly reducing postoperative pain, prosthetic loosening, and revision risks, while enabling smaller incisions and less trauma for faster patient recovery [6]. - Since its establishment in 2018, Yuanhua Intelligent has adhered to an independent technology route, breaking the international monopoly on high-end surgical robot core components and addressing the industry's long-standing reliance on imports [6]. - The successful implementation of the HX robotic arm at a top-tier hospital not only validates its safety and effectiveness in complex clinical scenarios but also demonstrates the adaptability and clinical value of domestic high-end medical equipment [6].
