Electroacupuncture Improves Pain and Wrist Functionality in Patients Undergoing Rehabilitation Therapy After Arthroscopic Repair for Triangular Fibrocartilage Complex (TFCC) Tears.

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. And, the postoperative goal is to restore the function of the forearm and the mobility of the wrist joint. Therefore, rehabilitation treatment is the key. However, postoperative patients often delay rehabilitation therapy due to pain, resulting in stiffer wrist joints. In recent years, electroacupuncture(EA) has been widely used to relieve pain after surgery, and many studies have confirmed that it is effective. And it is already an alternative to postoperative pain relief. The investigators hope that by electroacupuncture, the investigators can help patients reduce pain, increase joint mobility, and make patients willing to start rehabilitation therapy, reduce joint stiffness, and restore wrist function as soon as possible, which will help patients return to work and normal life early.
