Clinical predictors of medial knee osteoarthritis progression over 2 years

The overall aim of this study was to identify risk factors for knee osteoarthritis (OA) structural disease progression. More specifically, we aimed to identify what personal factors (age, sex, obesity, co-morbidity, Herberden’s nodes, history of injury, manual occupation and medication use), radiographic findings (Kellgren and Lawrence (K&L) grade, joint space width, alignment) and activity limitations (self-reported physical activity and physical function) independently predict medial knee joint space narrowing (JSN) over 2 years in people with painful medial knee OA.
