Characterization of Connective Tissue Using Streaming Potential Maps

Abstract — Editorial summary

This presentation explored relationships between matrix composition and electromechanical behaviour in cartilage and meniscus. Interleukin-1α-treated cartilage was compared with controls using biochemical assays, mechanical tests and spatial streaming-potential maps. Degradation reduced glycosaminoglycan content, increased collagen damage and lowered both stiffness and electrical response. Peripheral electrical changes appeared early. Separate meniscus measurements showed regional variation and substantially lower responses than articular cartilage. The work illustrates how spatial electrical mapping can characterize connective-tissue function and support development of an arthroscopic assessment approach.
