Variability in knee radiographing: implication for definition of radiological progression in medial knee osteoarthritis.


OBJECTIVES (1) To assess reproducibility of medial knee joint space width (JSW) measurement in healthy subjects and osteoarthritic (OA) patients. (2) To define minimal relevant radiological change in knee JSW based on the reproducibility of its measurement. PATIENTS AND METHODS (1) Healthy volunteers: in the first part of the study, 20 knees of healthy… (More)
