Quantitative Analysis of Surface Contouring with Pulsed Bipolar Radiofrequency on Thin Chondromalacic Cartilage

Figure 5

Photomicrographs of live/dead staining within the cartilage and underlying subchondral bone describing the (a) thermal penetration produced during treatment with B2 pattern and resultant cell viability with green dots indicating live chondrocytes, whilst red dots are dead chondrocytes. Representative image of caspase staining at (b) 24 hours post RFE treatment with blue dots showing nuclei of live chondrocytes whilst green dots labelled caspase-positive dead chondrocytes. Microscope magnification: 10x.
