Role of physical activity in cartilage damage progression of subjects with baseline full-thickness cartilage defects in medial tibiofemoral compartment: data from the Osteoarthritis Initiative

摘要

Objective: To assess the association between physical activity and cartilage damage progression in medial tibiofemoral compartment ( MTFC) using 2-year follow-up magnetic resonance imaging ( MRI) in subjects with denuded areas of subchondral bone ( dABs) at the central weight-bearing medial femur ( cMF) at baseline MRI examination.
