Compartmentalization according to the whole organ magnetic resonance imaging score (WORMS) of the knee in osteoarthritis. Each region of interest (ROI) was defined as follows: ROIs on the femoral articular cartilage were divided into an anterior area 45° from the line (MFC1, LFC1), a middle area 45° posterior from the line (MFC2, LFC2), and a posterior area 45° to 90° posterior from the line (MFC3, LFC3). ROIs on the tibial articular cartilage were divided into an anterior (MT1, LT1) and posterior area (MT2, LT2). Left: medial compartment. Right: lateral compartment. MFC medial femoral condyle, MT medial tibia, LFC lateral femoral condyle, LT lateral tibia (Quoted from Proffen et al. [35])
