Abstract — Editorial summary
This poster presents Arthro-BST mapping as a way to evaluate cartilage function across a joint surface. It combines a bovine enzymatic-degradation example, mapping around a naturally occurring focal defect and repeated measurements of human cartilage by several users. Electrical maps reflected matrix deterioration and regional differences, including relationships with meniscal coverage. The human mapping example showed an intraclass correlation of 0.87 between users. The work demonstrates the instrument’s measurement approach and laboratory applications, rather than proving early clinical diagnosis in an independent patient cohort.

Equipment used
Arthro-BST was used to map cartilage electromechanical function around a naturally occurring focal defect on a bovine humeral head and in a trypsin-treated bovine cartilage example. The handheld device measured streaming potentials during compression with its spherical indenter and calculated a local quantitative parameter. The focal-defect example used manual measurements at 30 surrounding locations.
