Population-based applications and validation- Cheryl Liu

Description

In this presentation, Cheryl Liu from Stryker addresses a group of surgeons about the quest to improve patient outcomes through innovations in knee implant design and robotic placement. She begins by discussing the importance of measuring patient-reported outcomes, specifically using the "forgotten joint score," which assesses how well patients can ignore their affected joint during daily activities. Liu explores the variability in natural knee kinematics across individuals, emphasizing that a one-size-fits-all approach is inadequate due to individual differences in anatomy and soft tissue response.



The talk progresses through a journey of research and development, explaining how Stryker has conducted high-speed biplane studies to analyze the kinematics of knee movements in a diverse group of elderly subjects. Liu highlights the need for physical testing and the creation of virtual models that can simulate natural knee movements. Throughout the discussion, she underscores the efforts made to develop a library of subject-specific kinematic models that capture the nuances of natural knee function.



By demonstrating the results from various testing methods, including physical and virtual cadaveric tests, Liu proposes that these models may help better understand how different implant designs could restore natural knee function. She concludes by affirming the importance of population-based validation in addressing clinical questions and improving knee implant designs, thanking her colleagues and academic collaborators for their support and contributions.
