Cartilage Streaming Potentials Measured with an Arthroscopic Medical Device Correlate with Site-specific Biochemical and Biomechanical Properties of Equine Articular Cartilage

Abstract — Editorial summary

This conference study compared Arthro-BST measurements with mechanical and biochemical properties at corresponding sites in two equine stifle joints. After electromechanical mapping, cartilage disks and rings were analysed for stiffness, permeability, glycosaminoglycans, collagen and collagen crosslinks. The instrument distinguished tibial plateau cartilage from femoral condyles and trochleae. Streaming potentials correlated with collagen quantity and mature crosslink content. Regional differences in mechanical properties and composition helped explain the electrical maps. The study provides laboratory evidence connecting probe measurements with cartilage function across joint surfaces.
