S/P Anterior Capsulorarrhaphy Anterior ETAC
The principle of electrothermally-assisted capsulorrhpahy (ETAC) is to apply enough heat to "loose" capsuloligamentous tissue to cause shrinkage of collagen fibrils through unwinding of the collagen triple helix. Disruption of hydrogen bonds transforms the tissue into a denatured state. ETAC can be applied using one of two sources of heat: laser or radiofrequency. The thermal energy is applied arthroscopically to tissue at a temperature of 65 degrees C.
