Abstract
Standard treatment for individuals with end-stage knee osteoarthritis (OA) is total knee arthroplasty (TKA), of which approximately 50% of patients will need a second TKA procedure within 10 years. Coordination and loading patterns of TKA patients have been identified in laboratory settings; however, data from an individual’s real-world environment must be collected to aid in the reduction of repeat TKA procedures. The goal of this project is to determine relationships between real-world performance and movement patterns in healthy individuals. Participants will perform 6-minute walk tests on indoor level surface, outdoor paved surface and unpaved surface, while wearing a wireless inertial-based gait system. We hypothesize that there will be greater variability on the unpaved surface than on the indoor surface. Initial data has indicated that distal shank acceleration was 51% more variable on the outdoor unpaved surface than the indoor level surface. Data also indicated greater variability in knee flexion angle (KFA) on the outdoor unpaved surface than the indoor level surface. This project will provide a foundation for future projects focusing on the prevention of repeat TKA procedures.
