An electrosurgical generator, having particular utility in surgical procedures on human joints, is provided with an output impedance in the range of 600 to 2,500 Ohms in order to efficiently transfer energy to the high impedance joint. The relatively high output impedance permits much lower power settings to be empolyed than are required by conventional electrosurgical generators so that little or no damage results in surrounding tissue. In the preferred embodiment, the output impedance range is 900 to 1,400 Ohms and is provided by an isolation transformer in which the turns ratio is selected to obtain the desired generator output impedance across the transformer secondary winding.
