Synopsis

Keywords: Osteoarthritis, MSKEarly hip osteoarthritis is clinically hypothesized to include alterations in joint motion and bone remodeling. This study investigated the relationships between lower-limb joint kinetics and bone remodeling, measured via positron emission tomography. Our results suggest that greater hip flexion and internal rotation loading and more uniform knee abduction loading are associated with bone remodeling and may serve as early biomechanical biomarkers for hip OA.
