Number of subjects with lesions (%), significance of trend (p<0.01) tested with logistic regression, covariates included age, sex, BMI, family history of knee replacement, history of knee surgery or injury, WOMAC pain, stiffness and disability (bilateral) hip and ankle pain (bilateral), average daily wear time of accelerometer. BMEP = bone marrow edema pattern.
