Evaluation of an Arthroscopic Probe for the diagnosis of Cartilage Degradation

Abstract — Editorial summary

This poster describes evaluation of a microelectrode-based arthroscopic probe for cartilage assessment. A controlled mechanical setup and manual measurements were used to examine electrical signals during indentation, including an enzymatic degradation model and a naturally occurring focal defect. Trypsin treatment reduced the mapped diagnostic response without an obvious surface change. Electrical mapping also helped identify the extent of impaired tissue around a defect. The work demonstrates laboratory sensitivity to matrix deterioration and explains how the probe derives a functional parameter from multiple electrical signals.
