Objective: This study retrospectively evaluates the functional outcomes of patients with triangular fibrocartilage complex (TFCC) foveal injuries treated arthroscopically with knotless double-row suture anchor repair.
Materials and Methods: Fourteen consecutive patients with Atzei type 2/3 TFCC foveal lesions were retrospectively analyzed. All were of working age and had an average follow-up of 15 months. Arthroscopic repair was performed using a knotless double-row suture anchor repair with monotunnel foveal anchorage. One suture fixed the volar radioulnar ligament, while the other secured the dorsal radioulnar ligament to the
fovea. Outcomes assessed included range of motion (ROM), grip strength, the Mayo Wrist Score, and the Disabilities of the Arm, Shoulder, and Hand (DASH) score.
Results: Improvements in pain and strength were observed. The Mayo Wrist Score results were rated as excellent or good. The average DASH score improved from 62 preoperatively to 8 postoperatively. Comparative grip strength was 80% of the contralateral side.
Conclusions: Arthroscopic repair of Atzei type 2/3 lesions using a double-row suture anchor repair with monotunnel ligament anchorage yields good outcomes, improving ROM, restoring stability, and achieving partial or total recovery of strength. Careful attention should be given to suture passage through the TFCC and screw fixation in the metaphysis to minimize complications.
