Arthroscopic-Assisted Inside-Out Foveal Reattachment of Triangular Fibrocartilage Complex

The dorsal and palmar radioulnar ligaments are the deep components of the triangular fibrocartilage complex (TFCC), which provides stability to the distal radioulnar joint (DRUJ). In patients with DRUJ instability, arthroscopic procedures are currently focused on reattachment of the deep components of the TFCC to the fovea of the ulnar head. TFCC-foveal reattachment can be performed either by using the transosseous technique with creation of a bone tunnel or by suturing to a bone anchor. Most previous studies of the TFCC suture method have used an outside-in technique. We herein present an arthroscopic inside-out TFCC-foveal reattachment technique with a bony anchor for the treatment of DRUJ instability. This technique has novel advantages, including less exposure, less soft-tissue dissection, and greater ease of TFCC suturing. This procedure may thus be considered another good option for the treatment of TFCC injury with DRUJ instability.
