Triangular fibrocartilage complex (TFCC) is an important structure for stability of distal radioulnar joint (DRUJ) and shock absorption of ulnocarpal joint. Recent studies on anatomy and biomechanics of TFCC have revealed that the deep fiber of distal radioulnar ligament plays a key role in stabilizing the DRUJ. Clinicians should evaluate the presence of the instability of DRUJ or ulnar impaction syndrome. If necessary, combined TFCC foveal repair and ulnar shortening osteotomy should be performed. This article introduces the authors’ preferred procedure of arthroscopic TFCC repair with satisfactory clinical outcomes.
