  1. Data are mean ± standard error The significance between groups is shown based on ANCOVA with adjustment for age. The differences are based on group0-group1, group1-group2 and group0-group2. * = p < 0.05. Group0 = control subjects, Group1 = mild OA subjects, Group2 = severe OA subjects. MFC = medial femoral condyle, LFC = lateral femoral condyle
