  1. * According to the Whole Organ Magnetic Resonance Imaging Score (WORMS), the knee joint is classified into tibiofemoral joint (including subspinous subregion, central and posterior, lateral and medial femoral subregions and lateral and medial tibial subregions) and patellofemoral joint (including anterior lateral and medial femoral subregions, and lateral and medial patellar subregions).
