A Workflow-Efficient Approach to Pre-and-Post Operative Assessment of Weightbearing 3D Knee Kinematics

Description

This presentation from the ISTA 2024 conference held in Nashville focuses on the evolution and practical application of knee kinematics examination technologies, highlighting their historical context and recent advancements. The speaker outlines their goal of demonstrating that a clinically practical knee kinematics examination is achievable, referencing key historical milestones dating back to 1836 and highlighting crucial advancements made during and after World War II.



The discussion includes a chronological study of various activities to assess knee movement, involving the use of modern imaging technology to capture kinematic data during exercises like lunging, sitting, and stair ascent. The examination process is designed to measure the dynamic movements of the knee after total knee arthroplasty, with a specific mention of the equipment used, including a digitally upgraded fluoroscopy system and the associated risks of X-ray exposure.



Results indicate that with an average exam time of approximately 7 minutes, which includes both dynamic and panoramic imaging, a comprehensive analysis of knee kinematics can be performed effectively. The speaker emphasizes that although the current methodology may yield more data than necessary for some activities, modifications can be made to optimize X-ray dose management while still obtaining meaningful kinetic data.



Ultimately, the core takeaway is that a standardized, practical approach to knee kinematics examinations is being developed, paving the way for improved clinical outcomes and facilitating future research, with anticipation for a follow-up comparison of this method against traditional techniques.
