The analyses are stratified by ipsilateral cartilage status at baseline (missing value for medial compartment for two knees and lateral compartment for one knee).
Numbers are n if not otherwise stated.
↵* Missing value for two knees for the lateral compartment.
↵† Poisson regression (using generalised estimating equations) adjusted for age, sex, body mass index, physical activity level, and mechanical axis at baseline.
BML, bone marrow lesion.
