An electrosurgical instrument includes a shaft, a flexible portion, and a head coupled to the shaft through the flexible portion and pivotably coupled to the flexible portion. The head includes a non-conductive surface and an electrically conductive surface. The flexible portion is configured to bias the non-conductive surface and the electrically conductive surface towards a tissue surface, such as cartilage. The non-conductive surface may include a material having a thermal conductivity less than or equal to about 30 W/m*K and/or a volume resistivity greater than or equal to about 1&#xd7;10ohm*cm. The non-conductive surface may include a ceramic such as Macor&#xae; ceramic, ZTA ceramic, and/or 99.5% alumina ceramic.
