A Study Evaluates the Effects of Electroacupuncture for Postoperative Pain Relief in Patients With Repair for TFCC Tears

Study Overview
=================
Brief Summary
-----------------
Triangular Fibrocartilage Complex (TFCC) is the main stable structure of the distal ulnar joint (DRUJ), and the damage of the triangular fibrocartilage complex is the most common cause of pain in the ulnar side of the wrist in the young athlete population. Once TFCC is injured, arthroscopic surgery is a common repair method. The postoperative analgesic method is generally oral or injection analgesic. In recent years, electroacupuncture(EA) has been widely used to relieve pain after surgery, and many studies have confirmed that it is effective. However, there is no evaluation of analgesic efficacy after arthroscopic repair of the TFCC. Therefore, it is hoped that the efficacy of electroacupuncture for analgesia after arthroscopic repair of the TFCC is demonstrated by this study. And, the investigators also hope the investigators can reduce the use of painkillers through electroacupuncture. Methods:It is expected that 30 patients will be randomly assigned to the following groups: electroacupuncture group(EAG), EA at points; non-point group (NPG), EA at non-points, control group (CG) without EA electroacupuncture group(EAG): EA at points after surgery non-point group (NPG): EA at non-points after surgery Control group: only injection painkiller were used before surgery

Acupoint selection: true acupoints: needles were inserted to Kunlun(BL60) and Sanyinjiao(SP6) contralateral to the operated leg and deqi sensation elicited at acupoints false point: the needles were inserted to Zusanli(ST36) and Shangjuxu(ST37) contralateral to the operated leg and deqi sensation elicited at acupoints Control group:only injection and oral painkiller were used before surgery Data collection: Record the time required for the first injection of analgesics The number of doses of injection painkiller used in 36 hours after surgery (count)
