Patellofemoral Kinematics during Different Loaded Dynamic Activities: An In-vivo Pilot Study

Description

This presentation by David Williams focuses on a pilot study investigating patellofemoral kinematics through in vivo techniques at the Musculoskeletal Biomechanics Research Facility. It outlines the limitations of conventional optical motion capture for measuring patellofemoral movements and introduces a novel approach using biplane video X-rays, which allow for non-invasive, high-speed imaging and analysis of bone motion. The study involved comparing kinematics during different dynamic activities—stair ascent, a lunge, and the stance phase of level gait—using custom-developed imaging protocols. Initial results indicated variability in kinematics across activities, highlighting the importance of examining multiple movements to better understand and improve patellofemoral interventions. The use of advanced imaging technology and a plan to include a larger, more diverse sample in future studies were also discussed. The session concluded with an opportunity for audience questions, delving into details about the volunteers and the safety of radiation exposure during the imaging process.
