Comparative Analysis of Radiological Evaluation and Early Functional Outcome of Total Knee Arthroplasty using Accelerometer-based Handheld Navigation System
Description
In this presentation, Dr. Nuthan Jagadeesh, a registrar at Wrightington Hospital, discusses a study on the effectiveness of a handheld navigation system, KneeAlign 2, compared to conventional instrumentation in total knee arthroplasty. The study focuses on the importance of accurate mechanical axis alignment for successful outcomes in knee surgeries and highlights the advancements in navigation technologies, particularly the handheld device, which offers a cost-effective alternative to robotics and computer navigation systems.
Dr. Jagadeesh outlines the study's methodology, noting a prospective design with two groups of patients: one receiving surgery with KneeAlign 2 and the other with standard methods. Key radiological parameters such as tibial alignment angle and femoral alignment angle were evaluated, showing significant improvements in the handheld navigation group. Although there was no difference in the functional outcomes measured by the Oxford Knee Score and Knee Society Score at a two-year follow-up, the handheld navigation system demonstrated superior accuracy in limb and implant alignment.
The presentation concludes with an emphasis on the advantages of using the handheld navigation system, including its patient-specific design, ease of use without the need for extensive preoperative preparation, and lower costs compared to traditional systems. Dr. Jagadeesh expresses gratitude and invites questions from the audience.
