Arthroscopic foveal reattachment of triangular fibrocartilage complex: Inside-out technique at specific ulnocarpal anatomical landmarks.

This study evaluates the outcomes of arthroscopic triangular fibrocartilage complex (TFCC) foveal reattachment using an inside-out suture passing through the TFCC at specific ulnocarpal anatomical landmarks to grasp the radioulnar ligaments. Thirty-eight patients with a mean age of 36 years (range 19-54), diagnosed with TFCC injury with distal radioulnar joint (DRUJ) instability, underwent arthroscopic inside-out TFCC foveal reattachment using designated suture sites. At a mean follow-up of 32 months (range 26-44), pain score, range of motion, grip strength, Disabilities of the Arm, Shoulder and Hand (DASH) score, and Modified Mayo Wrist Score all showed significant improvement after surgery. The DRUJ stability was restored and the minimal clinically important difference threshold for the DASH score was achieved in all patients. Arthroscopic TFCC foveal reattachment using the inside-out technique at specific ulnocarpal anatomical landmarks provided reliable outcomes and could be considered as another straightforward procedure for treating TFCC injuries with DRUJ instability.Level of evidence: IV.
