Evaluation of Cartilage Quality using Streaming Potential Maps

Abstract — Editorial summary

This poster investigated streaming-potential maps as indicators of cartilage health using two bovine degradation models. Interleukin-1α treatment was assessed during unconfined compression, while trypsin-treated tissue was examined during indentation. Biochemical assays documented matrix loss and damage, accompanied by changes in stiffness and electrical response. Alterations in peripheral potential gradients appeared before some central changes. The poster also describes an arthroscopic probe under development to acquire similar measurements directly from cartilage surfaces. The evidence concerns laboratory experiments and instrument development rather than a clinical outcome study.
