Fig. 1From: Comparison of properties determined using electromechanical assessment (Arthro-BST™) with macroscopic and histological properties in symptomatic human articular cartilage of the hipCartilage tissue assessment. A The ICRS classification was used to assess the cartilage of the femoral head (see Table 1 for the definition of the grades). B Schematic drawing of the Arthro-BST. The Arthro-BST induces streaming potentials using 37 microelectrodes. C The Arthro-BST was used to assess the same points assessed by the ICRS classification. D Cartilage sections were made by cutting perpendicular to the same points assessed using the ICRS classification and Arthro-BSTBack to article page
