Fig. 1From: Symptomatic bone marrow lesions induced by reduced bone mineral density in middle-aged women: a cross-sectional Japanese population studyRegional subdivision of the articular surfaces for the assessment of bone marrow lesions (BMLs). BMLs were assessed by the Whole-Organ MRI Scoring (WORMS) method. The patella, femur, and tibia were divided into medial (M) and lateral (L) regions. Region S represents the portion of the tibia beneath the tibial spines. The femoral and tibial surfaces were further subdivided into anterior (A), central (C), and posterior (P) regionsBack to article page
