摘要

全膝关节置换术（TKA）的成功取决于恢复正确的关节对齐和假体定位。虽然机器人辅助系统提高了初级TKA的精度，但由于骨质流失、软组织挛缩和金属伪影等挑战，它们在翻修TKA中的应用受到限制。本文提出了一种无图像机器人导航技术，用于修正TKA，消除了术前成像的需要，并允许术中灵活性。在记录解剖标志和植入物移除后，系统根据骨骼和软组织状况重新评估解剖结构进行迭代调整。与传统的运河参考方法不同，这种方法将组件相对于关节线对齐，从而实现个性化定位。实时反馈指导准确的骨切割和软组织平衡。一个案例示例说明了该过程。需要进一步的研究来证实长期的临床益处。

Surgical Technique for Imageless Robotic-Assisted Revision Total Knee Arthroplasty

Success in total knee arthroplasty (TKA) depends on restoring proper joint alignment and implant positioning. While robotic-assisted systems enhance precision in primary TKA, their use in revision TKA is limited due to challenges like bone loss, soft tissue contractures, and metal artifacts. This manuscript presents an imageless robotic navigation technique for revision TKA, eliminating the need for preoperative imaging and allowing intraoperative flexibility. After registering anatomical landmarks and implant removal, the system reassesses anatomy for iterative adjustments based on bone and soft tissue conditions. Unlike traditional canal-referenced methods, this approach aligns components relative to the joint line, enabling individualized positioning. Real-time feedback guides accurate bone cuts and soft tissue balancing. A case example illustrates the procedure. Further studies are needed to confirm long-term clinical benefits.

期刊介绍： Arthroplasty Today is a companion journal to the Journal of Arthroplasty. The journal Arthroplasty Today brings together the clinical and scientific foundations for joint replacement of the hip and knee in an open-access, online format. Arthroplasty Today solicits manuscripts of the highest quality from all areas of scientific endeavor that relate to joint replacement or the treatment of its complications, including those dealing with patient outcomes, economic and policy issues, prosthetic design, biomechanics, biomaterials, and biologic response to arthroplasty. The journal focuses on case reports. It is the purpose of Arthroplasty Today to present material to practicing orthopaedic surgeons that will keep them abreast of developments in the field, prove useful in the care of patients, and aid in understanding the scientific foundation of this subspecialty area of joint replacement. The international members of the Editorial Board provide a worldwide perspective for the journal''s area of interest. Their participation ensures that each issue of Arthroplasty Today provides the reader with timely, peer-reviewed articles of the highest quality.
