  1. Significant values are in [bold].
  2. Linear regression analysis is performed with bone marrow lesion scores in the whole joint, medial tibial plateau (MTP), and lateral tibial plateau (LTP) as dependent variables, and age, females, body mass index, loss of the knee extension angle, knee flexion angle, radiographic femorotibial angle, and bone mineral density (BMD) at the MTP, LTP, and metaphysis were independent variables. β: the standardized regression coefficient.
