A pain alleviation method as well as cartilage sparring or repairing method in the intraoperative as well as perioperative time of treatment device are disclosed herein. Pain maybe alleviated by applying a pulsed radio frequency (PRF) signal in the intraarticular as well as intrabursal or intracapsular area of a joint, while controlling the fluids in the joint area using suction. A device for carrying out the method includes a PRF electrode, a suction device, removing the fluids in the intraarticular and/or intracapsular and/or intrabursal area of a joint. The PRF electrode and suction device maybe collocated in a flexible tube that maybe applied through a cannula. PRF signal is applied to the electrode for approximately 10 minutes at 2 Hz with a pulse width of approximately 10 ms and approximately 55 V at approximately 42 degrees or similar setting.
